WPC Clutch Center Spring Cygnus X FI

[KITACO 307-0411340 WPC Clutch Center Spring for Cygnus X FI KITACO 307-0411340]
Special surface treatment & WPC specification for excellent heat resistance and high durability.
Significant improvement in heat resistance through nitriding and removal of residual stress in the surface layer through WPC treatment have greatly improved fatigue strength.
WPC clutch center springs strengthen the spring, promoting pulley shifting in the torque band. This quickly and forcibly returns the pulley from a high-ratio state to a low-ratio state during rapid acceleration from deceleration or on inclines, providing responsive shifting characteristics.
WPC clutch center springs are tuning parts, similar to weight rollers, so the optimal spring strength will vary depending on the rider's weight, the machine's usage, and even preferred riding characteristics.
Installing only the center spring can hinder shifting, potentially leading to a decrease in top speed.
