** KITACO clutch center springs are designed for high-tuned engines. Installing only a KITACO center spring on a stock vehicle with insufficient power may hinder gear shifting, potentially leading to performance loss.
* Examples of springs being too strong: The pulley may fail to shift while remaining in a low gear, resulting in a drop in top speed. The engine may reach its RPM limit even at low speeds, causing issues such as seizure or overheating.
* Clutch center springs are tuning (balance correction) parts, similar to weight rollers. The optimal spring strength varies depending on the rider's machine usage, body weight, and riding preference.
* Specifications are subject to change by the manufacturer without notice..
The clutch center spring plays the role of quickly and forcibly returning the pulley from a high-ratio state to a low-ratio state using spring force during sudden acceleration from deceleration in curves or on slopes. By strengthening the spring, KITACO clutch center springs allow for a quicker return to low gear, enabling sharper acceleration.
It shifts the engagement RPM (shift-keep RPM) of the V-belt transmission (pulley) to a higher range, providing powerful riding characteristics that maintain the torque band.
Points of Attention
