■ T-REV α system utilizes the STD solenoid valve mechanism to maintain moderate back torque (engine brake) when the acceleration is off, while emphasizing the smooth feeling of acceleration, eliminating the weak of engine brakes (street use).
Warning: Engine brakes are reduced, so please be careful when you use engine brakes. Please be careful with the mounting direction. Reverse installation may cause serious problems such as oil leakage. If installed in the opposite direction, the blow-by gas will not come out from the crankcase, and the oil seal may be directly connected to severe troubles, such as the gasket may come out, so please install it by a professional company
