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.
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.
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.

Variomatic is the continuously variable transmission (CVT) of the Dutch car manufacturer DAF, originally developed by Hub van Doorne. [1] It is a stepless, fully- automatic transmission , consisting of a V-shaped drive-belt, and two pulleys , each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle ...
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears.
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 transmission has three mode settings: Sport, Touring, and Rain.
