The Honda CBR600RR is a 599 cc (36.6 cu in) sport bike made by Honda since 2003, part of the CBR series . The CBR600RR was marketed as Honda's top-of-the-line middleweight sport bike, succeeding the 2002 Supersport World Champion 2001–2006 CBR600F4i , which was then repositioned as the tamer, more street-oriented sport bike behind the technically more advanced and uncompromising race-replica CBR600RR. It carried the Supersport World Championship winning streak into 2003, and on through 2008 , and won in 2010 and 2014 .
61-511: Honda's previous 600-class sport bike, the CBR600F4i , was considered a balance of practicality and performance, as capable as other Supersport-racing 600s, but a more docile and comfortable street bike relative to the competing Kawasaki Ninja ZX-6R , Suzuki GSX-R600 , and Yamaha YZF-R6 . When introduced in 1999, the CBR600F "fought off racier contenders on the track while still managing to be
122-600: A 0 to 97 kilometres per hour (0 to 60 miles per hour) time of 3.36 seconds and a quarter mile time of 11.03 seconds at 199.66 kilometres per hour (124.06 miles per hour). The CBR600F4 was produced between 1999 and 2000. Known as the CBR600F-X in Europe, it was the last of the CBR600 series of Honda sport bikes to be fuelled by carburettors . An all-new aluminium-alloy twin-spar frame which reduced frame weight
183-618: A 14 kg (33 lb) weight reduction (compared with previous ABS model) for a wet weight of 196 kg (433 lb). Some of the new features on the SP model are semi-active Öhlins Electronic Control suspension (S-EC), Brembo monobloc four-piston front brake calipers, titanium fuel tank and a 13:1 compression ratio. Also adding an even more exotic limited production "SP2" variant with Marchesini forged wheels and with larger valves of which 500 units will be sold. The CBR1000RR Fireblade received some electronic updates for 2019. The traction control
244-462: A 5 mm (0.20 in) increase over the 954. Accommodating the longer swingarm was another reason the CBR1000RR power plant shared nothing with the 954. Shortening the engine compared to the 954 meant rejecting the conventional in-line layout. Instead, engineers positioned the CBR1000RR's crankshaft, main shaft and countershaft in a triangulated configuration, with the countershaft located below
305-503: A comfortable and good handling sport bike for the street. Motor Cycle News said a Japanese source at Honda said that CBR600RR sales in Europe and the UK will end after the 2016 model year due to the redesign costs necessary to comply with Euro4 emissions regulations, which will come into effect on January 1, 2017. Sales of CBR600RRs in other markets are unaffected. The 2021 CBR600RR was released on 21 August 2020. Unlike previous models, it
366-508: A computer control unit to ensure the correct balance of front and rear brake use and also controlled when the ABS should engage. The system was designed to be as unobtrusive as possible by delaying the engagement of the ABS until the last possible moment. Combined ABS was not made available on the production 2008 CBR600RR. On September 5, 2008, Honda introduced a revised CBR600RR for the 2009 model year. Combined ABS became available as an option under
427-474: A corresponding reduced stroke. The engine had a completely new cylinder block, head configuration, and crankcase with lighter pistons. A new ECU had two separate revised maps sending the fuel and air mixture to be squeezed tight by the 12.3:1 compression ratio. Ram air was fed to an enlarged air box through two revised front scoops located under the headlamps. Honda made a very focused effort to reduce and centralize overall weight. A lighter, narrower die-cast frame
488-475: A deeper engine oil pan, sleeker tail fairings, seat and tail-light, and a revised engine cylinder head, netting about a 3.7 kilowatts (5 metric horsepower; 5 horsepower) gain over 1995–1996 models. The capacitor-discharge ignition (CDI) and ram-air system were also revised to allowed for smoother power curve over the 1995–1996 models, which could sometimes be jerky. The last made 1998 models were supplied with another revised engine cylinder head which resulted in
549-508: A fine-tuned ram-air system to increase torque. It also gets a new Showa "Big Piston Fork" and retuned rear shock in a new bodywork. The model continued unchanged through the 2017 model year. Motorcycle.com said that while the CBR600RR's performance specifications, particularly the horsepower, were "pretty tame even for the middleweight class", and it lacked the newest technologies like cornering ABS, traction control and mobile apps , it remained
610-481: A longer lever arm in the rear suspension for superior traction under acceleration and more progressive suspension action. Longer than the corresponding unit on the CBR954RR (585 mm (23.0 in) compared to 551 mm (21.7 in)) the CBR1000RR's 34 mm (1.3 in) longer swingarm made up 41.6 percent of its total wheelbase. The CBR1000RR's wheelbase also increased, measuring 1,405 mm (55.3 in);
671-426: A major revision with new bodywork, fully adjustable inverted front forks, disc brakes with radial-mounted four-piston calipers, and a new aluminum frame, swingarm and rear shock. The midrange power was also increased. These changes along with additional refinements to the engine and exhaust system brought CBR600RR's wet weight down by 10.0 kg (22 lb), and dry weight by 4.1 kg (9 lb). The 2006 model

#1732786552652732-455: A more practical streetbike", as described by Motorcyclist , "one golf club that acts like a whole bag." With the successor 2003 CBR600RR, Honda shifted to a more aggressive, less compromising strategy in the "churning dogfight that was the middleweight class at the time", Honda's CBR-RR Project Leader Hiroyuki Ito said, "We developed the RR in a completely different way from any model in the past. In
793-687: A new computer-controlled butterfly valve . The chassis was likewise all-new, including an organic-style aluminum frame composed of Gravity Die-Cast main sections and Fine Die-Cast steering head structure, inverted fork, Unit Pro-Link rear suspension, radial-mounted front brakes, and a centrally located fuel tank hidden under a faux cover. Additionally, the Honda Electronic Steering Damper (HESD) debuted as an industry first system which aimed to improve stability and help eliminate head shake while automatically adjusting for high and low speed steering effort. A longer swingarm acted as
854-498: A performance oriented "SP" variant. For 2017, with the 25th anniversary of the Fireblade, Honda has updated its flagship CBR (SC77) with new bodywork and features such as throttle-by-wire and traction control for the first time that works with selectable ride modes. A retuned engine which now produces a claimed 189 hp (141 kW) and 153.2 hp (114.2 kW) at the rear wheel, a 10 hp increase, titanium muffler and
915-527: A rear hugger, single seat cover, and an LCR sticker kit as well as combined braking and ABS . The CBR600F shares most of the components with the CB600F Hornet naked bike , such as inverted front forks, though longer by 50 millimetres (2.0 inches) and aluminium mono-backbone frame. It is wrapped in a multi-layered full fairing that lowers drag and protects the rider from wind-blast, as well as new instruments, handlebars and fuel tank. It also retains
976-536: A similar relaxed seating position to minimise rider fatigue. The 2011 CBR600F also shares the engine of the highly revised CB600F model that was released in April 2007. This engine is a detuned version of that which is available in the 2007 CBR600RR, giving a maximum output power of approximately 76 kilowatts (103 metric horsepower; 102 horsepower) at 12,000 rpm and 65 newton-metres (47.9 pound force-feet) of torque at 10,500 rpm. All specifications are claimed by
1037-652: A slight power gain. In 1999, it was replaced by the CBR600F4. In 1996 and 1998, the F3 was also sold in 'Smokin' Joe's Replica' versions in the United States, Canada, and Australia (1998 only). Cycle World tested the F3's acceleration from 0 to 97 kilometres per hour (0 to 60 miles per hour) at 3 seconds and 0 to 402 metres (0 to 1 ⁄ 4 mile) at 10.9 seconds at 201.62 kilometres per hour (125.28 miles per hour). Motorcycle Consumer News recorded
1098-504: A smaller version, called CBR500F , was offered. The subsequent models are designated as CBR600F2, F3, F4, and F4i respectively. In 2011, Honda released a more modern model with the same name. The original CBR600F, along with the CBR750F and CBR1000F were Honda's first inline four-cylinder, fully-faired sport bikes. The style was said to be influenced by a brief European trend toward a smooth and completely enclosed fairing such as in
1159-560: A smaller, lighter rear caliper. The 2006 model carried over to the 2007 model year mostly unchanged except for color options. An all-new ninth-generation RR (SC59), the CBR1000RR was introduced at the Paris International Motorcycle Show on September 28, 2007, for the 2008 model year. The CBR1000RR was powered by an all-new 999 cc (61.0 cu in) inline-four engine with a redline of 13,000 rpm. It had titanium valves and an enlarged bore with
1220-580: Is also enhanced, giving the throttle plates more quick reaction to the rider's inputs. For 2020, the CBR1000RR is updated along with a new name (CBR1000RR-R) for the SP model which is race inspired, with redesigned bodywork and new engine based on technologies used in RC213V MotoGP bike. The CBR1000RR was awarded Cycle World's International Bike of the Year for 2008–09 by the world's moto-journal communities as well as journalists. The 2009 CBR1000RR won
1281-522: Is now 14,200 rpm, 700 rpm higher than the previous year's F4. To increase the bike's pulling capabilities at high speeds, the fifth and sixth gears have been shortened slightly, and the rear sprocket was enlarged from 45 teeth to 46, also adding one additional clutch plate for greater durability to now totalling eight. The oiling holes in the camshafts have been enlarged by 0.5 millimetres (0.02 inches) (to 2.5 millimetres (0.10 inches)), and piston ring friction has been decreased to aid cooling at

#17327865526521342-463: Is now separated from the wheelie control, meaning both systems can be controlled independently. The dashboard now has a three-position ‘W’ setting, alongside the Power, Engine Braking and Honda Selectable Torque Control (HSTC) traction settings. The ABS settings has also been tweaked, giving less intervention above 120 km/h (75 mph) and giving 15% more deceleration. The ride-by-wire throttle motor
1403-421: Is smaller with a new dual-bulb configuration. The F4i had a new dash layout with a large analogue tachometer. The new LCD digital display had a speedometer, odometer, clock, engine temperature read-out, amber shift light, and trip meters. The single largest change aside from the styling is the addition of high-pressure 50 pounds per square inch (340 kilopascals) PGM-FI (programmed fuel injection ) system, thus
1464-543: Is sold only in Japan and Oceania. Updated equipment include a TFT instrument panel and reworked bodywork. For the 2007 model year, the CBR600RR competed with the Ducati 749 , a completely redesigned Kawasaki Ninja ZX-6R, Suzuki GSX-R600, Triumph Daytona 675 , and Yamaha YZF-R6. Shootout comparisons by motorcycle magazines consistently awarded the CBR600RR first place in the super sport class. Major print and online publishers said
1525-590: The 2019 season , the Honda engines were replaced by a Triumph 765 cc (46.7 cu in) straight-three engine . Honda CBR600F4i The Honda CBR600F is a CBR series 600 cubic centimetres (36.6 cubic inches) inline four-cylinder sport bike motorcycle made by Honda Motorcycles . The first model of the CBR600F was sold from 1987 to 1990 and is known in the US as the Hurricane . In Austria and Mexico,
1586-686: The Ducati Paso . The CBR600F2 was produced from 1991 to 1994. It was introduced to replace the original CBR600F Hurricane, and for its time, was considered one of Honda's most modern and innovative sport bikes. Development of the CBR600F2 began in early 1989. Hurricane LPL Ishikawa led the development of the new motorcycle, known internally as MV9 but also called the F2, an alphanumeric that led to its official name: CBR600F2. The F2's development began with meetings to discuss concepts and sketches for
1647-401: The 2006 CBR600RR. The handling of the new bike was sharpened by its 22 mm (0.87 in) shorter wheelbase, as well as by the designer's focus on strict mass centralization. Despite the shorter wheelbase, the 2007 model's swingarm was 5 mm (0.20 in) longer than that of the 2006, made possible by the more compact dimensions of the new bike's engine. The suspension of the 2007 model
1708-731: The 7th generation of the CBR series of motorcycles that began with the CBR900RR in 1992. The Honda CBR1000RR was developed by the same team that was behind the MotoGP series. Many of the new technologies introduced in the Honda CBR600RR , a direct descendant of the RC211V , were used in the new CBR1000RR such as a lengthy swingarm , Unit Pro-Link rear suspension , and Dual Stage Fuel Injection System (DSFI). The seventh-generation RR (SC57),
1769-562: The CBR600 won eight out of twelve titles since its introduction in 2003, and ten manufacturers' crowns since 2003. Michael Dunlop holds the supersport lap record at the Isle of Man TT on a CBR600RR. In the 2010 season , with the introduction of the four-stroke Moto2 class in the MotoGP World Championship , the engines for the class were based on the CBR600RR, with a maximum power of 150 bhp (110 kW). Starting in
1830-793: The CBR600F4i was also released in Europe and Australia (2001 & 2002 only) in two 'Rossi Replica' versions. In 2011, Honda released the new CBR600F model built in Italy for the European markets that was not released in America. It continues the legacy of the CBR-F line. To honour the German rider Stefan Bradl , Honda Germany launched a special edition of the CBR600F, called CBR600F LCR. It featured an Arrow titanium exhaust, Progrip handlebar grips,
1891-550: The CBR600RR had a powerful engine and class-leading light weight. For the 2008 model year, the CBR600RR continued to compete with the Ninja ZX-6R, a revised GSX-R600, Daytona 675, and a R6. Even with no technical changes from the 2007 model, the CBR600RR continued to win middleweight shootouts at by Sport Rider , Motorcycle-USA, and Motorcycle.com. As of 2015, in the Supersport World Championship,

1952-703: The H4 bulbs in the predecessor. The headlights are dual multi-reflector units covered by a one-piece clear polycarbonate lens. The turn indicator stalks are shorter, and the rear-view mirrors are now positioned higher and closer to the rider. The elimination of carburetors allowed for a slightly larger air box and a larger 4.8 US gallons (18.2 litres; 4.0 imperial gallons) fuel tank. And a fuel consumption of 36.7 miles per US gallon (6.41 litres per 100 kilometres; 44.07 miles per imperial gallon). In 2001 and 2002, in recognition of Honda's association with MotoGP champion Valentino Rossi and its 500th motorcycle Grand Prix victory,
2013-471: The Honda CBR1000RR, was the successor to the 2002 CBR954RR. While evolving the CBR954RR design, few parts were carried over to the CBR1000RR. The compact 998 cc (60.9 cu in) in-line four was a new design, with different bore and stroke dimensions, race-inspired cassette-type six-speed gearbox, all-new ECU -controlled ram-air system, dual-stage fuel injection, and center-up exhaust with
2074-452: The RC211V. Honda said that the use of its new 'Hollow Fine Die Cast' frame technology, in which sand casting molds were given a ceramic interior coating, made it possible to reduce the thickness of the five-piece aluminum frame from 3.5 mm to 2.5 mm. The 2003 model carried over to 2004 technically unchanged, with only the addition of an oxygen sensor. In 2005, the CBR600RR received
2135-450: The earlier model, and less weight. Changes for 2006 included: A revised front fairing design, new rear suspension with new linkage ratios 135 mm, along with a new chassis geometry, and a new lighter swingarm. A new intake and exhaust porting (higher flow, reduced chamber volume). A higher compression ratio (from 11.9:1 to 12.3:1). The cam timing was revised. Intake valve lift was increased from 8.9 mm to 9.1 mm. Double springs for
2196-410: The engine and front wheel for a large radiator. Engineers solved this problem by giving the RR a modest cylinder incline of 28°, and moving the oil filter from its frontal placement on the 954 to the right side of the 1000RR engine. This allowed the RR's center-up exhaust system to tuck closely to the engine. The eighth generation RR (SC58) was introduced in 2006 and offered incremental advancements over
2257-505: The fairing mid-sections that enhance stability and reduce noise emission levels by now totally enclosing the clutch and gearbox. Although all of these changes involved the addition of some materials, the overall weight of the 2009 CBR600RR remained the same as the 2008 model. This was achieved through weight savings in the engine, exhaust, and the chassis. The CBR600RR carried over for the 2010, 2011 and 2012 model years. The 2013 CBR600RR includes new 12-spoke wheels, revised ECU settings, and
2318-434: The final testing of this model. The CBR600F4i was produced from 2001 to 2006. The upgraded F4i is a modified F4 with numerous engine, chassis and bodywork changes. The 2001 US F4i had a new subframe which raises the seat by 5 mm (0.2 in) that allows for more under-seat storage room and improved two-tier seat. The new tail unit has less padding and a higher perch for the pillion passenger. The F4i's taillight
2379-450: The frame and was separated from the sides of the fairing by a large gap which Honda said was for air management purposes. The tail-section was similarly smaller and sharper-edged, riding atop a heavily restyled under-seat muffler. On June 9, 2008, Honda revealed a CBR600RR prototype that had an all new braking system branded as Combined ABS which integrated combined braking , anti-lock braking , and brake-by-wire systems. Combined ABS used
2440-440: The front end. The suspension has also been tweaked with less high-speed damping and a little more low-speed damping with the shock and fork being more street-bias. Additional engine changes include a lighter camshaft sprocket and increased valve spring pressure (two springs per intake valve) which allow for higher revving. There are new piston rings that slide with less friction and increased internal engine oil flow. Redline
2501-559: The front, and a single-piston caliper and a 220 mm (8.7 in) disc at the rear. Hidden below the steering head was an updated version of the Honda Electronic Steering Damper (HESD) system, which was also available on the CBR1000RR . The smaller, sharper-edged new front upper fairing was dominated by the large central ram-air duct which fed the airbox through an opening in the steering head section of
Honda CBR600RR - Misplaced Pages Continue
2562-446: The higher rev ceiling. Spring pressures on the intake and exhaust valves have been increased to avoid valve float . Also, there are now two valve springs (inner and outer) on the intake side instead of the single item that resides on the exhaust side. The F4i's new bodywork carries a more racy look and provides a 3% reduction in drag. It also houses a new dual headlight front cowl design which uses 40% brighter H7 bulbs compared to
2623-425: The injectors add up to 3.7 kilowatts (5 metric horsepower; 5 horsepower) over the non-injected F4. The weight of the road wheels was reduced. The brake disc carriers moved out closer to the brake calipers to reduce weight and to improve rigidity. But stopping power still was not on par with other bikes in the class. There is additional bracing on the steering head for more response, better feedback and feel from
2684-432: The intake valves were implemented. The engine RPM redline was increased from 11,250rpm to 12,200rpm. A larger rear sprocket was fitted (from 41 to 42 teeth). New exhaust system. The disk brakes were changed with a larger diameter 320 mm (13 in) front brake discs but thinner at 4.5 mm (0.18 in) as well as a larger 220 mm (8.7 in) rear brake discs but thinner at 4.5 mm (0.18 in) Along with
2745-590: The main shaft, dramatically shortening the engine front to back, and moving the swingarm pivot closer to the crankshaft. This configuration was first successfully introduced by Yamaha with the YZF-R1 model in 1998 and inspired superbike design in the following years. Positioning this compact engine farther forward in the chassis also increased front-end weight bias, an effective method of making high-powered liter bikes less wheelie prone under hard acceleration. This approach, however, also provided very little space between
2806-492: The manufacturer unless otherwise specified. The best-known song by American singer-songwriter David Wilcox , "Eye of the Hurricane", refers to this motorcycle. Honda CBR1000RR The Honda CBR1000RR , marketed in some countries as the " Fireblade " (capitalized as FireBlade until the 2000s ), is a 999 cc (61.0 cu in) liquid-cooled inline four-cylinder superbike , introduced by Honda in 2004 as
2867-451: The model (CBR600RA). Other changes included updates to the engine such as changes to its pistons, cylinder head and exhaust that Honda claims will increase torque delivery between 8,000–12,000 rpm with a 3.5% increase in torque at 10,000 rpm. The CBR600RR's engine also received a new high resistance valve lifter and a popup valve system inherited from the CBR1000RR. It looks were the same as last year apart from some extra mouldings added to
2928-614: The model designation 'F4i'. In a number of countries, the bike was sold in both the 'normal' and 'Sport' variants, the Sport having a two-part seat, no pillion grab rail, and no main stand (though the main stand mounting holes remained). Fuel injection allows for more precise fuel metering and delivery over a wider rpm range, while providing better throttle response and reducing emissions. The fuel injectors reside one per cylinder, and are aspirated through four 38 millimetres (1.5 inches) throttle bodies. Each injector has four nozzles, and together
2989-500: The new motorcycle. A few months later, an F2 prototype was produced. Painted black, the bike looked faster and sleeker than the more blocky first generation bike, and test results were superior: few motorcycles in the 1990s had the performance ability of the F2. The CBR600F3 was the third generation of the CBR600F series. Replacing the F2, the F3 was produced from 1995 to 1998. It had a modified engine, ram-air intake, and cartridge front forks. The 1997 and 1998 models also came with
3050-448: The past Honda has always developed a roadbike, then modified it for racing. But with the RR, we first built a prototype racer, then gave it to the production department." Rotating an aging model down to the next tier of a product line as it is overshadowed by a model with the latest technology is common practice among sport bike manufacturers including Buell , Ducati , Honda, Kawasaki , Suzuki , Triumph , and Yamaha . The 2003 CBR600RR
3111-409: The primary focus of the redesign. The result was a 9.1 kg (20 lb) reduction in dry weight over the 2006 model, from a claimed 163.7 kg (361 lb) to 154.7 kg (341 lb). Tested weights without fuel were 182–182 kg (401–402 lb). In redesigning the CBR600RR for lighter weight and increased performance, Honda's engineers started with the engine. The completely new engine

#17327865526523172-455: The rear wheel width increased to 140 millimetres (5.5 inches) with new three-spoke wheels. The F4 was fitted with Honda's HISS electronic engine immobiliser system. The phrase "Dedicated to Super Evaluators Dirk Vandenberg and Josef Boyd " are embossed in raised letters on the inside of the F4's upper fairing; the dedication to two of Honda R&D's senior product developers who were killed during
3233-517: Was based on technologies used in the Honda RC211V MotoGP bike, and was given a similar appearance. It was the first Honda to use Unit Pro-Link rear suspension, a variant on the single rear shock absorber with the upper mount connected to the rear swingarm subframe to help isolate undesirable forces transmitted to the steering head. It also was the first to use Honda's Dual Stage Fuel Injection (PGM-DSFI): both were taken directly from
3294-454: Was carried over almost unchanged from the 2006 bike, with the same 41 mm (1.6 in) inverted fork in front, and Honda's Unit Pro-Link rear suspension configuration damping the rear wheel. The new three-spoke cast aluminum wheels were also lighter than those on the 2006 bike, which further contributed to the enhanced performance of the suspension. The brakes had dual radial-mount four-piston calipers and twin 310 mm (12 in) discs at
3355-441: Was formed using a new technique which Honda claimed allowed for very thin wall construction and only four castings to be welded together. Almost every part of the new bike was reengineered to reduce weight, including the sidestand, front brake hoses, brake rotors, battery, and wheels. In order to improve stability under deceleration, a slipper clutch was added, with a center-cam-assist mechanism. The Honda Electronic Steering Damper
3416-543: Was redesigned for quicker removal when preparing the motorcycle for track use. The muffler cover was also redesigned for improved appearance. The twelfth-generation Fireblade celebrated its 20th anniversary, revised for 2012, featuring Showa 's Big Piston suspension technology, Showa balance-free shock, further improved software for the combined ABS, new 12-spoke wheels, aerodynamic tweaks, an all LCD display and other minor updates. Retuned engine for additional power, modified rider position along with new windscreen. Also added
3477-447: Was revised as well. Another significant change was the exhaust system, which was no longer a center-up underseat design. The new exhaust was a side-slung design in order to increase mass centralization and compactness while mimicking a MotoGP-style. On September 5, 2008, Honda announced the tenth generation of the RR as a 2009 model. The bike remained much the same, in terms of engine, styling, and performance. The only significant addition
3538-409: Was smaller and lighter than its predecessor, the designers having used careful positioning of all internal components to achieve reductions in the motor's length, width, and height, as well as reducing weight by 2 kg (4.4 lb) compared to the 2006 model's powerplant. Horsepower increased to about 105 hp (78 kW) measured in independent tests. The frame was lighter and more compact than
3599-507: Was the introduction of the optional factory fitted Combined ABS (C-ABS) system originally showcased on the CBR600RR Combined ABS prototype . New, lightweight turn signals were also added. On September 4, 2009, Honda announced the eleventh generation of the RR as a 2010 model. Honda increased the diameter of the flywheel for more inertia. This improved low-rpm torque and smoother running just off idle. The license plate assembly
3660-400: Was unchanged from the 2005 model. On September 6, 2006, Honda revealed an all new CBR600RR for the 2007 model year. The CBR600's most radical redesign since the introduction of the RR in 2003 is highlighted by a whole new engine, frame, and bodywork that results in a smaller, lighter, more-powerful CBR600RR with a class-leading power-to-weight ratio and unparalleled performance. Weight was
3721-550: Was used, and the engine crankcase was designed to share the swingarm pivot. Through a reduction of internal friction and weight, combined with larger valves, shorter stroke and a bigger bore , higher maximum engine operating revolutions were enabled. The spark plug caps had ignition coils built into them. Slightly larger carburettor were fitted, and the oil cooler was now located by the oil filter. A new suspension had larger 43 millimetres (1.7 inches) forks and used Fireblade parts. The dual front disc brakes were upgraded, and
