What does a primary clutch spring do?

The primary clutch spring works with your machine's clutch system to control when the clutch engages and what the engine's maximum RPM can be. Adjusting this spring helps match your vehicle's performance to different riding conditions and styles.

Why is the 5% tolerance important?

A tight tolerance of 5% means the spring's performance will be very consistent and reliable. This is the lowest tolerance in the industry, ensuring predictable results when you tune your clutch.

What is the load rating for this spring?

This EPI Brite Green spring has a load rating of 123 lbs at 1.25 inches, 38 lbs at 2.25 inches, and 17 lbs at 2.5 inches. These figures help you understand how it will affect your clutch engagement.
