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.
In 1879, Milton Reeves invented a CVT (then called a variable-speed transmission) for use in sawmilling. In 1896, Reeves began fitting this transmission to his cars, [31] and the Reeves CVT was also used by several other manufacturers. The 1911 Zenith Gradua 6HP motorcycle used a pulley-based Gradua CVT.
The Aprilia Mana 850 is an automatic transmission motorcycle made by Aprilia from 2007 to 2016.. The Mana has an 839.3 cc (51.22 cu in) 90° V-twin engine with a continuously variable transmission (CVT).
The NuVinci CVT system has a small number of parts. [5] [6] Most CVTs have lower mechanical efficiency than competitive conventional transmissions.Since any CVT may allow a power plant, human or motorized, to operate at (or closer to) its speed of optimal efficiency, output torque or output power, the NuVinci CVT may improve a system's overall efficiency or performance compared to a ...
A continuously variable transmission (CVT) can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.
As of the 2020 model year, all Spyder models are equipped with a semi-automatic transmission and Ryker models are equipped with fully automatic continuously variable transmissions (CVT). The manual transmissions follow the standard motorcycle design: a left-foot-actuated shifter and a left-hand-actuated clutch. [6] The semi-automatic ...
Honda DN-01 transmission controls. The electronic controls allow the motorcycle to be operated in three modes: Drive, Sport and Manual. In Drive and Sport, it functions much like a CVT scooter, with infinitely variable gearing upshifted and downshifted automatically for what the system determines to be optimal performance.
At the rear of the swingarm, a centrifugal clutch connects the transmission to a simple integral gear-reduction unit. There is no clutch of any kind between the CVT and the crankshaft; it is engaged via a centrifugal clutch at the rear pulley in the same fashion as Vespa Grande, Bravo, and variated Ciao model, as well as Honda Camino/Hobbit ...
