Torque Spring-Hard- Stage6 Yamaha Aerox / BWs

Description

Stage6 torque springs, available in 3 different strengths.
Pressure on the belt is one of the key factors in a transmission. If the spring is too soft, the belt might slip and rub against the side of the pulley. If the spring is too hard, the belt will be kept from moving. In both cases, you will lose power to the rear wheel, so don’t forget to check on them!
