An electronic control system for a clutch on a motorcycle includes a sensor configured to measure a parameter indicative of a performance or speed of the motorcycle. The sensor is configured to provide an input signal corresponding to the parameter to a computer control system, which includes a microprocessor and memory. The microprocessor and memory are configured to manipulate the input signal and the microprocessor is configured to output a control signal that controls an actuator that is configured to manipulate a position of the clutch.

Electronics control of motorcycle clutch

A motorcycle includes a front wheel drive train that supplies power to a front wheel and a rear wheel drive train that supplies power to a rear wheel. The front wheel drive train is configured to drive the front wheel at a selected rate that is faster than a rate at which the rear wheel drive train drives the rear wheel. Driving the front wheel at the selected faster rate relative to the rear wheel provides enhanced steering capabilities in soft terrain, as the front wheel pulls the motorcycle in a direction that the front wheel is pointed.

All wheel drive motorcycle with enhanced soft terrain capabilities

An all wheel drive motorcycle includes an internal combustion engine having an output shaft extending from the engine. A back wheel drive train is coupled to the output shaft with either a first chain or a first shaft. The first chain or the first shaft couples to a rear wheel drive sprocket or a rear wheel drive gear that couples to the first chain or first shaft, respectively. The motorcycle includes a front wheel drive train that extends from the output shaft to a universal joint that is positioned on the motorcycle within a range of about plus or minus ten degrees of perpendicular to the steering axis of rotation of the front fork where the front fork supports and retains the front wheel. The universal joint and the output shaft are coupled together with either a second drive chain or a second drive shaft. The universal joint includes a stub shaft having a front wheel drive sprocket engaging a front wheel drive chain where the front wheel drive chain also engages a front axle sprocket that supplies a drive force to the front wheel.
