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 ...
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 ...
Quickshifter on a BMW S1000RR motorcycle. 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 [ 1 ] and allow for faster gear shifting (usually shifting in less than 50 milliseconds) and is thus a ...
An automatic transmission with a manumatic function provides a greater level of control by allowing the driver to request an upshift or downshift at a specific time. This is usually achieved using "+" and "-" positions on the gear selector or with paddle-shifters mounted beside the steering wheel.
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 Honda automobile torque converter had a lockup, leading the company to sell the original Hondamatic (which had just two forward gear ratios) as a three-speed. The true three-speed H3 was launched in 1979. In 1982 Honda introduced a four-speed fully-automatic (called Hondamatic Full-Auto), followed by a fully-automatic three-speed in 1983 ...
