Quickshifter
A quickshifter (or quick shifter) is a device that eliminates the need to use the clutch or throttle when shifting gears on a manual transmission. This can increase the safety and comfort of the vehicle and allow for faster gear shifting (usually shifting in less than 50 milliseconds) and is thus a popular performance enhancement for motorcycles. Working mechanism Almost all quickshifters work on the same basis, a sensor detects the gear shift action, a microcontroller (CPU) processes the data (and calculates the timing) and cuts off ignition momentarily, resulting in a reduction of the load at the transmission allowing the new gear to slip (and engage) into place. However the method of sensing and reducing the load can vary. Sensor Most gearshift sensors work by measuring the pressure change (push or pull) on the shift rod. However, some sensors use a strain gauge, which is more expensive but may be more reliable and free from false readings due to vibrations since it has no ...

Clutchless Gear Shifting
A semi-automatic transmission is a "theoretical" multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input would be required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo, while still requiring the driver to manually shift gears.

Motorcycle Transmission
A motorcycle transmission is a transmission created specifically for motorcycle applications. They may also be found in use on other light vehicles such as motor tricycles and quadbikes, go-karts, offroad buggies, auto rickshaws, mowers, and other utility vehicles, microcars, and even some superlight racing cars. Manual gearing Most manual transmission two-wheelers use a sequential gearbox. Most motorcycles (except scooters) change gears (of which they increasingly have five or six) by a foot-shift lever. On a typical motorcycle, either first or second gear can be directly selected from neutral, but higher gears may only be accessed in order – it is not possible to shift from second gear to fourth gear without shifting through third gear. A five-speed of this configuration would be known as "one down, four up" because of the placement of the gears with relation to neutral, though some motorcycle gearboxes and/or shift mechanisms can be reversed so that a "one up, four down" sh ...

Kawasaki Ninja ZX-10R
The Kawasaki Ninja ZX-10R is a motorcycle in the Ninja sport bike series from the Japanese manufacturer Kawasaki, the successor to the Ninja ZX-9R. It was originally released in 2004 and has been updated and revised throughout the years. It combines an ultra-narrow chassis, low weight, and radial brakes. In 2004 and 2005 the ZX-10R won ''Best Superbike'' from '' Cycle World'' magazine, and the international Masterbike competition. Components Engine Kawasaki engineers used a stacked design for a liquid-cooled, inline four-cylinder engine. The crankshaft axis, input shaft, and output shaft of the Ninja ZX-10R engine are positioned in a triangular layout to reduce engine length, while the high-speed generator is placed behind the cylinder bank to reduce engine width. With a bore and stroke of , the ZX-10R engine's one-piece cylinder, and crankcase assembly reduces weight and increases rigidity.

KTM Duke 390
The KTM 390 Duke and RC 390 are displacement single-cylinder engine motorcycles assembled by Bajaj Auto, and KTM Asia Motorcycle Manufacturing, Inc. (KAMMI) for the Austrian manufacturer KTM. The bikes were developed under a joint program of Bajaj and KTM engineers, in which the concept was developed in Austria, while everything else, including design and final product development, was done in India by Bajaj. The 390 Duke standard debuted at the 2012 EICMA show in Milan, Italy, and went on sale in India and the Philippines in 2013 and in the US in 2015. The RC 390 sport bike was presented at EICMA the following year. After the Duke's initial release, KTM CEO Stefan Pierer announced plans to export the 390 Duke to the US for 2014. Bajaj said eventually the bike will be sold in 80 countries worldwide. Pierer said in December 2015 that KTM and Bajaj plan to replace the 125, 200, and the 390-series Duke and RC lines in 2017, based on all new platforms, in part tarnavo meet Euro IV ...

Kawasaki Ninja H2
The Kawasaki Ninja H2 is a " supercharged supersport"-class motorcycle in the Ninja sports bike series manufactured by Kawasaki, featuring a variable-speed centrifugal supercharger. Its namesake is the 750 cc Kawasaki H2 Mach IV, an inline triple that was introduced by Kawasaki in 1972 to "disrupt what it saw as a sleeping motorcycle market". Its Ninja H2R track-only variant is the fastest and most powerful production motorcycle on the market, producing a maximum of and with ram-air. The H2R has 50% more power than the fastest street-legal motorcycles, while the street-legal Ninja H2 has a lower power output of – with ram-air. Design Kawasaki selected the literbike platform for its top-of-the-line Ninja H2 model, rather than continuing with the higher-displacement Ninja ZX-14 hyperbike. '' Cycle World'''s Kevin Cameron explained that the literbike class is "the center of the high-performance market", attracting the best development in racing, with the bes ...

Throttle
A throttle is the mechanism by which fluid flow is managed by constriction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term ''throttle'' has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a ''throttle'' (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft. For a steam locomotive, the valve which controls the steam is known as the regulator. Internal combustion engines In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. For a gasoline engine, the throttle most commonly regulates the amount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Stability Control
Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology that improves a vehicle's stability by detecting and reducing loss of traction ( skidding). When ESC detects loss of steering control, it automatically applies the brakes to help steer the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer. Some ESC systems also reduce engine power until control is regained. ESC does not improve a vehicle's cornering performance; instead, it helps reduce the chance of the driver losing control of the vehicle. According to the U.S. National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety in 2004 and 2006 respectively, one-third of fatal accidents could be prevented by the use of the technology. In Europe the el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Control (automotive)
Launch control is an electronic aid to assist drivers of both racing and street cars to accelerate from a standing start. Motorcycles have been variously fitted with mechanical and electronic devices for both street and race. Popular automobiles with launch control include the BMW M series, certain marques of the Volkswagen Group with Direct-Shift Gearbox (most notably the Bugatti Veyron), Porsche 911 (sport+ mode), Panamera Turbo, Alfa Romeo with TCT gearbox and certain General Motors products. Mitsubishi also incorporated launch control into their Twin Clutch SST gearbox, on its "S-Sport" mode, but the mode is only available in the Evolution X MR and MR Touring (USDM). The Jaguar F-Type includes launch control. The Nissan GT-R has electronics to control launch but the company does not use the term "launch control" since some owners have equated the term with turning off the stability control to launch the car, which may void the warranty of the drivetrain. One version of Nis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-lock Braking System
An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle. ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practiced by skillful drivers before ABS was widespread. ABS operates at a much faster rate and more effectively than most drivers could manage. Although ABS generally offers improved vehicle control and decreases stopping distances on dry and some slippery surfaces, on loose gravel or snow-covered surfaces ABS may significantly increase braking distance, while still improving steering control. Since ABS was introduced in production vehicles, such systems have become increasingly sophisticated and effectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Control
A traction control system (TCS), also known as ASR (from german: Antriebsschlupfregelung, lit=drive slippage regulation), is typically (but not necessarily) a secondary function of the electronic stability control (ESC) on production motor vehicles, designed to prevent loss of traction (i.e., wheelspin) of the driven road wheels. TCS is activated when throttle input and engine power and torque transfer are mismatched to the road surface conditions. The intervention consists of one or more of the following: *Brake force applied to one or more wheels *Reduction or suppression of spark sequence to one or more cylinders *Reduction of fuel supply to one or more cylinders *Closing the throttle, if the vehicle is fitted with drive by wire throttle *In turbocharged vehicles, a boost control solenoid is actuated to reduce boost and therefore engine power. Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylinder ...
