What does a primary clutch spring do?

The primary clutch spring works with the clutch weights to control when your clutch engages and disengages. Changing the spring allows you to adjust the engagement speed and the engine's top RPM, tailoring performance to different riding conditions.

Why is the 5% tolerance important?

A tight tolerance of 5% means the spring's performance will be very consistent and predictable. This is crucial for clutch tuning, as it ensures reliable engagement and RPM characteristics every time you ride.

What is the load rating of this spring?

This EPI primary spring has a load rating of 175 lbs at 1.25 inches and 125 lbs at 2.5 inches. These figures indicate the spring's stiffness at different compression points, which directly affects clutch engagement.
