Compatible models Cygnus X-SR (FI car): BF91 | Cygnus X/Cygnus X-SR (FI car): 1YP all models | Cygnus 5S9 Free length: 115mm Outer diameter: 62.3mm Load when used: 374N Special surface treatment & WPC specification that resists heat sagging and exhibits high durability

The WPC clutch center spring strengthens the spring to encourage the pulley to shift in the torque band, quickly and forcibly shifting the pulley, which was previously in a high ratio state, from deceleration to sudden acceleration, or on slopes, to a low ratio. , and you can get crisp shifting characteristics. In addition, by applying a composite treatment that includes WPC to the surface, it exhibits stable performance even when used for long periods of time at high temperatures. The WPC clutch center spring is a setting part just like weight rollers, etc., so the best spring strength will vary depending on the driver's weight, how much the machine is used, and even riding characteristics preferences. Even if only the center spring is installed, it will interfere with gear shifting and may result in a reduction in top speed.
