The Honda VFR1200F is the 7th generation Honda sport touring motorcycle from the VF and VFR line motorcycles powered by a transverse mounted V4 engine.The VFR1200F has several new technologies including the first dual clutch transmission offered on a motorcycle.
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.
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 ...
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 ...
The VTX1300 engine had a cable-operated clutch, instead of the hydraulic clutch of the VTX1800. [7] The 1300 engine used an air injection system and catalytic converters, similar to the bigger engine, as well as a lean fuel-air mixture to control emissions. [24]
The MT-09 is the first Yamaha motorcycle since the XS750 and XS850 to be powered by inline-three engines. Both are shaft-driven motorcycles produced from 1976 to 1981. In 2017, the MT-09 was updated with fully adjustable suspension, traction control, antilock brakes, slipper clutch, LED headlights, and updated styling. [2]
In the early 1960s, Jawa invented the first automatic clutch for motorcycles. The centrifugal clutch was designed for Jawa 250/559 and 350/360. Because the clutch has been patented worldwide by Jawa and it was copied in the Honda 50 Cub motorcycle, Honda had to retreat, pay a fine, and pay a license fee for each motorcycle sold.
This unit was an early semi-automatic transmission, based on the design of a conventional manual transmission, which used a servo-controlled vacuum-operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch ...
