GEAR-PS-SWT-PUSH-PULL This system is a standalone unit, which can be fitted to a motorbike-powered car. When the driver pulling a lever calls for an up-shift, the shift rod then sends a signal to the control box, which then initiates a spark cut by breaking the supply to the coil or coils. This means the driver does not need to use the clutch on the up-shift. Due to the way the system controls the smooth spark cut means that the driver will barely notice the up-change, not only can this be done under full power but also in mid corner which significantly reduces time because the driver can concentrate on the circuit rather than the gear change.
