Abstract
The dual clutch transmission (DCT) for motorcycles that provides direct response to throttle operations without interruption of traction at shift was developed and installed on the VFR1200F.This system has two separate hydraulic circuits for two clutches to provide individual controls. Weak creep control at departure, deceleration adaptive shift-down control, predictive cornering shift control, and other controls were developed to achieve the advanced performances in the vehicle departure and the shift change characteristic that are demanded for motorcycles. With those performances, riders can enjoy the pleasures of riding without depending on rider’s skills. Compact design of this DCT system has made it possible to share the same crankcase raw casting materials with manual transmission (MT) type which is developed in parallel, and this design has enabled the installation on the common frame with MT system.
