Transmission

The VFR1200F is available with either a conventional sequential manual transmission, or an automatic dual clutch transmission (DCT),[12] both of which are mated to shaft final drive. The DCT version, known is some markets as the VFR1200FD, has dual clutches, one operating 1st, 3rd and 5th gears, the other operating 2nd, 4th and 6th gears. The dual clutches are able to switch quickly between gears and can operate in one of three modes: 'D', which is a fuel-efficient fully automatic mode; 'S', a sports automatic mode, which changes gear at higher engine speeds; and manual mode, in which the rider changes gear using paddles fitted to the handlebars. This gearbox is the first of its type fitted to a large capacity motorcycle, although dual clutch transmissions are already used in automobiles. Unlike the continuously variable transmission installed on scooters, which use a pulley, the DCT gearbox retains engine braking as with a conventional manual transmission.
