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 will be. Adjusting this spring can help you better match your vehicle's performance to your riding style and the terrain you're on.

Why is the 5% tolerance important?

A strict 5% tolerance means the spring's performance will be very consistent and reliable. This is important for predictable clutch engagement and performance, especially when you're out riding.

What is the base load and load at different points?

The base load is the initial force of the spring when it's not compressed. The 32mm and 60mm loads indicate how much force is required to compress the spring to those specific measurements, helping you understand its engagement characteristics.
