Springs for ADVANTAGE Special Clutch Spring Kit for Standard Model are manufactured at KYB / SHOWA's specialized suspension spring factory.
The important thing is the clutch spring, as the world of clutches seems to have too many out-of-the-box products until now.
This is partly due to the fact that springs themselves have high tolerance values when they are manufactured.
Advantage has developed a clutch spring using valve spring material (SWOSC-V) in a factory specializing in suspension springs, based on our long experience in suspension development.
The spring material SWOSC-V is used, and the inclination difference of the spring is less than 0.5 degrees, and the special shot peening processing is done, and the clutch of a stock motorcycle is reexamined and redesigned.
The spring rate is designed to be reduced by oil temperature.
■About the suspension spring rate
Fundamentally overcame the situation where the clutch is just hard and heavy, which is often the case with reinforced clutches.
It eliminates the need to increase the spring rate so drastically in synergy with the friction and plate.(In some models, clutch slippage is suppressed by the spring rate)
This model tends to be heavy, but it is lighter than the rival products.
■Clutch spring material
As mentioned above, SWOSC-V is used as the clutch spring material.
This is a valve spring material.
This material is used where the performance cannot be compromised in an environment that is far more severe than that of a clutch.
The most notable thing is that the wire diameter (piano wire) differs in every tenth of a second depending on the models and the specifications, so there are few spring manufacturers who have the material in a timely manner, but suspension specialist manufacturers do not.
ADVANTAGE has enough wire diameters to cover most of the requirements and can produce products with wire diameters according to the design, resulting in high-performance and long-life products.
