72-525: The Royal Enfield Himalayan is an adventure touring motorcycle manufactured by Royal Enfield . It was revealed in February 2015 and launched in early 2016. Pierre Terblanche led the design team during Himalayan's development. The Himalayan was conceived by CEO Siddhartha Lal , as an adventure touring , or dual sport motorcycle. The Himalayan differs considerably from the other motorcycles offered by Royal Enfield – most of which are various incarnations of
144-640: A century, caused Royal Enfield to cut production by 4,000 motorcycles in November 2015, followed by a shutdown of the plants in Thiruvottiyur and Oragadam on 1 December, as well as the company offices in Chennai. Production resumed at 50% capacity on 7 December and operations at both plants were back to normal on 14 December. Royal Enfield announced its first takeover of another company in May, 2015 with
216-810: A dealership in Milwaukee, Wisconsin, with the intention to offer three bikes, the Bullet 500 , Classic 500 and Continental GT 535 Cafe Racer as they feel this engine size represents an under-served market. The dealership will be Royal Enfield's first company-owned store in the U.S., according to Rod Copes, president of Royal Enfield North America. The company wants to establish about 100 dealerships in American cities starting with Milwaukee. Later in August 2015, parent-business Eicher announced its entry in Indonesia as
288-563: A friction wheel set against the rim should scale fairly linearly with wheel size, almost as if it were rolling along the ground itself) but are unsuitable for off-road use, and must be kept properly tensioned and clean of road dirt to avoid slipping or jamming. Most speedometers have tolerances of some ±10%, mainly due to variations in tire diameter. Sources of error due to tire diameter variations are wear, temperature, pressure, vehicle load, and nominal tire size. Vehicle manufacturers usually calibrate speedometers to read high by an amount equal to
360-560: A lower ground clearance at 200mm (compared to 220mm of the Himalayan). Royal Enfield (India) Royal Enfield is an Indian multinational motorcycle manufacturing company, headquartered in Chennai . The Royal Enfield brand, including its original British heritage, is the oldest global motorcycle brand in continuous production. The company operates manufacturing plants in Chennai , India . The first Royal Enfield motorcycle
432-936: A maximum speed above 50 km/h (31 mph) (or a cylinder capacity, if powered by a heat engine , of more than 50 cm (3.1 cu in)). European Union Directive 2000/7/EC, which relates to two- and three-wheeled vehicles, provides similar slightly relaxed limits in production. There were no Australian Design Rules in place for speedometers in Australia before July 1988. They had to be introduced when speed cameras were first used. This means there are no legally accurate speedometers for these older vehicles. All vehicles manufactured on or after 1 July 2007, and all models of vehicle introduced on or after 1 July 2006, must conform to UNECE Regulation 39. The speedometers in vehicles manufactured before these dates but after 1 July 1995 (or 1 January 1995 for forward control passenger vehicles and off-road passenger vehicles) must conform to
504-569: A much cruder time/distance resolution – typically one pulse/display update per revolution, or as seldom as once every 2–3 seconds at low speed with a 26-inch (660 mm) wheel. However, this is rarely a critical problem, and the system provides frequent updates at higher road speeds where the information is of more importance. The low pulse frequency also has little impact on measurement accuracy, as these digital devices can be programmed by wheel size, or additionally by wheel or tire circumference to make distance measurements more accurate and precise than
576-513: A new lineup of cruiser motorcycles on 6 November 2020 named the Meteor. It replaced the Thunderbird 350 and 350X series which were discontinued earlier that year. It uses a 349 cc single cylinder engine featuring a single overhead camshaft system (SOHC), and a completely new engine with fewer moving parts than the 346 cc. A 648 cc, air cooled version of the bike has been revealed named
648-426: A new rear sub-frame, 17 inch alloy wheels, and a 140mm telescopic fork front suspension, while reducing the stroke value of the rear suspension to 150mm. The bike features a minimalistic design with a smaller 11 litre fuel tank while retaining the round LED headlamp and flat-style handlebar, common amongst its three variants. Speedometer A speedometer or speed meter is a gauge that measures and displays
720-570: A part of its global strategy in the mid-sized (250–750 cc) motorcycle segment, initially starting retail operations from a dealership in Jakarta. From April to September 2015, Royal Enfield's domestic sales were 50% higher than the previous year, despite a declining motorcycle market in India. The Royal Enfield Bullet has the longest and unchanged production run of any motorcycle having remained continuously in production since 1948. The Bullet marque
792-576: A particular ambient temperature and road surface. There are slight differences between the different standards, for example in the minimum accuracy of the equipment measuring the true speed of the vehicle. The UNECE regulation relaxes the requirements for vehicles mass-produced following type approval. At Conformity of Production Audits the upper limit on indicated speed is increased to 110 percent plus 6 km/h (3.7 mph) for cars, buses, trucks, and similar vehicles, and 110 percent plus 8 km/h (5.0 mph) for two- or three-wheeled vehicles that have

The factory-custom bobber based on the same platform as the new Continental GT 650. A limited edition Shotgun was launched at the Motoverse 2023 with an attractive blue-and-black color scheme. Later on the production version was revealed which had the same specifications as the Motoverse edition except
936-445: A power output of 24.5 bhp at 6,500 rpm (18.02 KW) and a maximum torque of 32 Nm at 4,000-4,500 rpm. The engine also includes an oil cooler, a first among motorcycles manufactured by Royal Enfield India. The bike employs electronic fuel injection and the engine is mated to a 5-speed constant mesh transmission. This engine has a single overhead camshaft, thereby moving away from the traditional pushrod design that had been used by
1008-408: A rotating flexible cable driven by gearing linked to the vehicle's transmission . The early Volkswagen Beetle and many motorcycles, however, use a cable driven from a front wheel. Some early mechanical speedometers operated on the governor principle where a rotating weight acting against a spring moved further out as the speed increased, similar to the governor used on steam engines. This movement
1080-673: A speedometer, which was usually fitted to locomotives . The electric speedometer was invented by the Croat Josip Belušić in 1888 and was originally called a velocimeter. The speedometer was originally patented by Josip Belušić (Giuseppe Bellussich) in 1888. He presented his invention at the 1889 Exposition Universelle in Paris . His invention had a pointer and a magnet, using electricity to work. German inventor Otto Schultze patented his version (which, like Belušić's, ran on eddy currents) on 7 October 1902. Many speedometers use
1152-461: A standard tire is "185/70R14" with diameter = 2*185*(70/100)+(14*25.4) = 614.6 mm (185x70/1270 + 14 = 24.20 in). Another is "195/50R15" with 2*195*(50/100)+(15*25.4) = 576.0 mm (195x50/1270 + 15 = 22.68 in). Replacing the first tire (and wheels) with the second (on 15" = 381 mm wheels), a speedometer reads 100 * ((614.6/576) - 1) = 100 * (24.20/22.68 - 1) = 6.7% higher than the actual speed. At an actual speed of 100 km/h (60 mph),
1224-624: A suitable motorcycle for its army to patrol the country's border. In 1952 the Royal Enfield Bullet was chosen as the most suitable bike for the job. In 1954, the government ordered 800 in units of the 350 cc model. In 1955, the Redditch company partnered with Madras Motors in India to form 'Enfield India' to assemble, under licence , the 350 cc Royal Enfield Bullet motorcycle in Madras (now called Chennai). The tooling
1296-441: A typical motor vehicle gauge. However, these devices carry some minor disadvantages in requiring power from batteries that must be replaced every so often in the receiver (and sensor, for wireless models), and, in wired models, the signal is carried by a thin cable that is much less robust than that used for brakes, gears, or cabled speedometers. Other, usually older bicycle speedometers are cable driven from one or other wheel, as in
1368-448: Is also used for a variety of other purposes by the ECU or full-vehicle control system, e.g. triggering ABS or traction control, calculating average trip speed, or increment the odometer in place of it being turned directly by the speedometer cable. Another early form of electronic speedometer relies upon the interaction between a precision watch mechanism and a mechanical pulsator driven by

1800-538: Is sold. European Union member states must also grant type approval to vehicles meeting similar EU standards. The ones covering speedometers are similar to the UNECE regulation in that they specify that: The standards specify both the limits on accuracy and many of the details of how it should be measured during the approvals process. For example, the test measurements should be made (for most vehicles) at 40, 80 and 120 km/h (25, 50 and 75 mph), and at
1872-637: Is taking proactive steps to ensure the quality of its adventure motorcycle, the Royal Enfield Himalayan". In 2022 its ex-showroom price in India started at ₹ 2.14 lakh (US$ 2,600).

2736-476: The United Kingdom later that year. Electronic Fuel Injection and ABS became standard in 2017. The 2021 model got significant upgrades such as the Tripper navigation system powered by Google Maps (same unit offered in new Meteor ) and a redesigned jerrycan mount. Upon its introduction, the Himalayan was praised for its good suspension and off-road ability, while some criticism was directed to
2808-424: The accuracy of these signals and result in inaccurate speed readings. Typical bicycle speedometers measure the time between each wheel revolution and give a readout on a small, handlebar-mounted digital display. The sensor is mounted on the bike at a fixed location, pulsing when the spoke-mounted magnet passes by. In this way, it is analogous to an electronic car speedometer using pulses from an ABS sensor, but with
2880-674: The average error, to ensure that their speedometers never indicate a lower speed than the actual speed of the vehicle, to ensure they are not liable for drivers violating speed limits. Excessive speedometer errors after manufacture can come from several causes, but most commonly is due to nonstandard tire diameter, in which case the error is: Percentage error = 100 × ( 1 − new diameter standard diameter ) {\displaystyle {\mbox{Percentage error}}=100\times \left(1-{\frac {\mbox{new diameter}}{\mbox{standard diameter}}}\right)} Nearly all tires now have their size
2952-441: The car's wheel or transmission. The watch mechanism endeavours to push the speedometer pointer toward zero, while the vehicle-driven pulsator tries to push it toward infinity. The position of the speedometer pointer reflects the relative magnitudes of the outputs of the two mechanisms. A virtual speedometer is a computer-generated tool that displays the current speed of a vehicle or object. The virtual speedometer typically calculates

Royal Enfield produce a range of accessories for the Himalayan, including a crash guard, bash plate, headlight guard, top rack and top box. Various of aftermarket suppliers have also entered the market, widening the range of such products. The Himalayan has a half-duplex split cradle frame. Suspension
3168-403: The cup, which itself produces another magnetic field. The effect is that the magnet exerts a torque on the cup, "dragging" it, and thus the speedometer pointer, in the direction of its rotation with no mechanical connection between them. The pointer shaft is held toward zero by a fine torsion spring . The torque on the cup increases with the speed of rotation of the magnet. Thus an increase in
3240-443: The end of 2019, the team numbered 155 and carries out the full spectrum of design and development activities, from concept generation and clay design to engineering design, prototyping and validation. Royal Enfield currently sells motorcycles in more than 50 countries. Royal Enfield surpassed Harley-Davidson in global sales in 2015. In August 2015, Royal Enfield Motors announced it is establishing its North American headquarters and
3312-435: The instantaneous speed of a vehicle. Now universally fitted to motor vehicles , they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. Other vehicles may use devices analogous to the speedometer with different means of sensing speed, eg. boats use a pit log , while aircraft use an airspeed indicator . Charles Babbage is credited with creating an early type of
3384-550: The legislated error in speedometer readings is ultimately governed by the United Nations Economic Commission for Europe (UNECE) Regulation 39, which covers those aspects of vehicle type approval that relate to speedometers. The main purpose of the UNECE regulations is to facilitate trade in motor vehicles by agreeing on uniform type approval standards rather than requiring a vehicle model to undergo different approval processes in each country where it
3456-406: The motorcycle speedometers described above. These do not require battery power, but can be relatively bulky and heavy, and may be less accurate. The turning force at the wheel may be provided either from a gearing system at the hub (making use of the presence of e.g. a hub brake, cylinder gear, or dynamo) as per a typical motorcycle, or with a friction wheel device that pushes against the outer edge of
3528-580: The object's speed based on the distance it travels over time. Such speedometers are programmed using programming languages such as HTML, CSS, and Javascript. The program uses the mobile device's GPS module. Consistent use of the GPS module on mobile devices can result in faster battery drain. Furthermore, virtual speedometers calculate speed by measuring the distance and time between two points using GPS signals. However, various environmental factors such as weather conditions, terrain, and obstructions can interfere with
3600-417: The output shaft or (in transaxles) differential crown wheel, or a toothed metal disk positioned between a magnet and a magnetic field sensor . As the part in question turns, the magnets or teeth pass beneath the sensor, each time producing a pulse in the sensor as they affect the strength of the magnetic field it is measuring. Alternatively, particularly in vehicles with multiplex wiring, some manufacturers use
3672-544: The previous Australian design rule. This specifies that they need only display the speed to an accuracy of ±10% at speeds above 40 km/h, and there is no specified accuracy at all for speeds below 40 km/h. All vehicles manufactured in Australia or imported for supply to the Australian market must comply with the Australian Design Rules. The state and territory governments may set policies for
SECTION 50
#17328010594903744-521: The pulses coming from the ABS wheel sensors which communicate to the instrument panel via the CAN Bus . Most modern electronic speedometers have the additional ability over the eddy current type to show the vehicle's speed when moving in reverse gear. A computer converts the pulses to a speed and displays this speed on an electronically controlled, analogue-style needle or a digital display . Pulse information
3816-749: The purchase of a UK motorcycle design and manufacturing firm, Harris Performance Products , that had previously developed the chassis of the Royal Enfield Continental GT Cafe Racer. Harris work with the UK-based part of Royal Enfield's development team, who are based at the UK Technology Centre at Bruntingthorpe Proving Ground in Leicestershire. The team was established in January 2015, and moved into their new, purpose-built facility in May 2017. By
3888-410: The relatively low power output of the engine. The motorcycle also has longer intervals between servicing and oil changes . The early Himalayan suffered some production issues. It was noted that the quality of parts was not up to the mark and in 2017 some users filed lawsuits to either demand compensation or return the bike for refund. The company responded and in 2018 it was reported that "Royal Enfield
3960-400: The rim (same position as rim brakes, but on the opposite edge of the fork) or the sidewall of the tire itself. The former type is quite reliable and low maintenance but needs a gauge and hub gearing properly matched to the rim and tire size, whereas the latter requires little or no calibration for a moderately accurate readout (with standard tires, the "distance" covered in each wheel rotation by
4032-400: The speed of the car will twist the cup and speedometer pointer against the spring. The cup and pointer will turn until the torque of the eddy currents on the cup are balanced by the opposing torque of the spring, and then stop. Given the torque on the cup is proportional to the car's speed, and the spring's deflection is proportional to the torque, the angle of the pointer is also proportional to
4104-424: The speed, so that equally spaced markers on the dial can be used for gaps in speed. At a given speed, the pointer will remain motionless and point to the appropriate number on the speedometer's dial. The return spring is calibrated such that a given revolution speed of the cable corresponds to a specific speed indication on the speedometer. This calibration must take into account several factors, including ratios of
4176-402: The speedometer will indicate 100 x 1.067 = 106.7 km/h (60 * 1.067 = 64.02 mph), approximately. In the case of wear, a new "185/70R14" tire of 620 mm (24.4 inch) diameter will have ≈8 mm tread depth, at legal limit this reduces to 1.6 mm, the difference being 12.8 mm in diameter or 0.5 inches which is 2% in 620 mm (24.4 inches). In many countries
4248-413: The strength of increased demand for its motorcycles. This was followed in 2017 by the inauguration of another new factory of a similar size to the facility at Oragadam (capacity 600,000 vehicles per year) at Vallam Vadagal. The original factory at Tiruvottiyur became secondary, and continues to produce some limited-run motorcycle models. Flooding , produced by the heaviest rainfall in Chennai in over
4320-402: The tail shaft gears that drive the flexible cable, the final drive ratio in the differential , and the diameter of the driven tires . One of the key disadvantages of the eddy current speedometer is that it cannot show the vehicle speed when running in reverse gear since the cup would turn in the opposite direction – in this scenario, the needle would be driven against its mechanical stop pin on

#17328010594904464-479: The tolerance of speed over the posted speed limits that may be lower than the 10% in the earlier versions of the Australian Design Rules permitted, such as in Victoria. This has caused some controversy since it would be possible for a driver to be unaware that they are speeding should their vehicle be fitted with an under-reading speedometer. The amended Road Vehicles (Construction and Use) Regulations 1986 permits
4536-439: The tyres are manufactured by Pirelli (MT-60). The motorcycle has a 300 mm disc with a dual piston floating caliper at the front and a 240 mm single piston caliper disc at rear. The instrumentation console for this motorcycle is also modeled anew. It includes an analog speedometer and tachometer , with a digital display for the odometer, gear position indicator, trip-meter and Ambient temperature gauge. Also included
4608-549: The use of speedometers that meet either the requirements of EC Council Directive 75/443 (as amended by Directive 97/39) or UNECE Regulation 39. The Motor Vehicles (Approval) Regulations 2001 permits single vehicles to be approved. As with the UNECE regulation and the EC Directives, the speedometer must never show an indicated speed less than the actual speed. However, it differs slightly from them in specifying that for all actual speeds between 25 mph and 70 mph (or
4680-416: The vehicle is in motion, a speedometer gear assembly turns a speedometer cable, which then turns the speedometer mechanism itself. A small permanent magnet affixed to the speedometer cable interacts with a small aluminium cup (called a speedcup ) attached to the shaft of the pointer on the analogue speedometer instrument. As the magnet rotates near the cup, the changing magnetic field produces eddy current in
4752-710: The vehicles' maximum speed if it is lower than this), the indicated speed must not exceed 110% of the actual speed, plus 6.25 mph. For example, if the vehicle is actually traveling at 50 mph, the speedometer must not show more than 61.25 mph or less than 50 mph. Federal standards in the United States allow a maximum 5 mph error at a speed of 50 mph on speedometer readings for commercial vehicles. Aftermarket modifications, such as different tire and wheel sizes or different differential gearing, can cause speedometer inaccuracy. Starting with U.S. automobiles manufactured on or after 1 September 1979,
4824-423: The zero position. Many modern speedometers are electronic . In designs derived from earlier eddy-current models, a rotation sensor mounted in the transmission delivers a series of electronic pulses whose frequency corresponds to the (average) rotational speed of the driveshaft , and therefore the vehicle's speed, assuming the wheels have full traction. The sensor is typically a set of one or more magnets mounted on
4896-550: Was also used to create the Royal Enfield Guerrilla 450 , which was launched in 2024. The Himalayan's engine was designed and produced by Royal Enfield 'from the ground up' and shares little to no parts with other contemporaries in the company's line-up. The engine, named the LS410 indicating its long-stroke ratio, is a unit-construction 411 cc single-cylinder, oil-cooled 4-stroke SOHC engine. The motor generates
