The designers at Moto Guzzi were aiming the V1000 Convert at the US police motorcycle market and were the first to produce a big capacity automatic motorcycle with shaft drive. Moto Guzzi increased the pushrod-operated V-twin's bore and stroke to give a displacement of 949 cc (57.9 cu in), and replaced manual gearbox with a torque converter ...
The original Servi-Cycle design had the engine drive the rear wheel by belt, with no transmission or clutch, requiring the engine to be shut off while the cycle is at rest. [8] In 1941, a pedal-operated clutch was added. [10] By 1950, Simplex added a belt-type automatic transmission.
Underbone and miniature motorcycles often have a three to five-speed foot-shift lever, but the clutch is automatic (usually a centrifugal clutch). This type of clutchless (no manual clutch) transmission still must have the gears shifted manually by the rider, and the system is commonly known as a semi-automatic transmission.
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
An early example of a semi-automatic motorcycle transmission was the use of an automatic centrifugal clutch in the early 1960s by the Czechoslovakian manufacturer Jawa Moto. [83] Their design was used without permission in the 1965 Honda Cub 50 , which resulted in Jawa suing Honda for patent infringement and Honda agreeing to pay royalties for ...
The Honda CM450A is a motorcycle made by Honda in 1982 and 1983. It was based on the CB400 and CM400 models (1978–1981), especially the CM400A Hondamatic (1980–1981). It had a 447 cc (27.3 cu in) SOHC parallel twin engine with two carburetors and a two-speed transmission with a torque converter. It was not a full automatic, however, because ...
Clay Ridley began experimenting with automatic transmissions in motorcycles in 1995, when building them for his sons as a hobby. [2] Although the vast majority of cars and light trucks sold in the U.S. use automatic transmissions, no two-wheeled vehicles larger than a scooter did, and so to capitalize on that market, he and his son Jay founded the Ridley Motorcycle Company in 1997, which ...
The 1400GTR is fitted with a keyless ignition, KIPASS (Kawasaki's Intelligent Proximity Activation Start System), [3] which means that no key is needed to start the bike as long as the rider is carrying the coded transponder—typically in a pocket. From launch the 1400GTR had the option of an anti-lock braking system (ABS).
