*The camshaft lift is 5.6mm, which is different from the actual valve lift. *When installing, check for interference with the pistons and other components due to the amount of lift.
This is the original profile type X high camshaft that fits both Japanese and Taiwanese BWS125.
The lift is the same as ADVANCEPro Type Y camshafts, but the overlap angle is reduced compared to the Y camshafts to match the valve diameter, as most users in this class use stock heads or mid size valves. The target displacement is set to the optimum lift and overlap for displacements between 156cc and 180cc.
It depends on the characteristics of the engine, but if the overlap angle of CYGNUS 4V engine is increased, the amount of blowout will be increased and the torque in the low and mid range will be decreased, making it difficult to ride on the street. The lift is determined by the valve diameter, port diameter, displacement and other data, and the overlap angle is set to a profile that can secure enough torque at mid-speed, which is the most important for street use. The Type X has been designed to have the best response with the most torque in the mid range by setting the overlap angle against the amount of lift, and the cam profile has been changed to have the best high rpm response.
ADVANCEPro currently offers 4 different profiles of camshafts to suit a wide range of displacement tuning applications.
Type N for 125cc Type X 156-180cc Type Y 180-220cc Type Z 220-300cc
