Estimating the term…
A speed change controlling apparatus in which the mode of driving force transmission is depends upon the roll angle of a vehicle body. When a roll angle is within a range from a second roll angle, which corresponds to a full bank state, to a first roll angle, speed change operation is carried out by soft speed change control in which variation of the driving force with respect to time is smaller than that by normal speed change control. If the roll angle is within another range from the first roll angle to a third roll angle, then normal speed change is carried out and if the roll angle is within a further range from an uprightly standing state to the third roll angle, then speed change operation is executed by direct speed change. When the roll angle is greater than the second roll angle, speed change is inhibited.
A speed change controlling apparatus for a motorcycle which includes an engine adapted to generate driving force for the motorcycle, the speed change controlling apparatus disposed between said engine and a driving wheel and adapted to carry out speed change for the driving force of said engine to transmit the resulting driving force to the driving wheel, roll angle detection device for detecting a roll angle of the motorcycle, and a control section adapted to control said speed change controlling apparatus in response to a predetermined speed changing request but control said speed change controlling apparatus not to carry out normal speed change control when the roll angle exceeds a first roll angle, wherein:
