What is the purpose of a secondary clutch spring?

The secondary clutch spring works with the clutch weights to control when your clutch engages and disengages. A different spring rate can change how quickly and firmly the clutch engages, affecting throttle response and power delivery.

What does the 5% tolerance mean for this spring?

A 5% tolerance means the spring's actual load rating will be within 5% of its stated specifications. This consistency helps ensure reliable and predictable performance from your clutch system.

Is this spring a direct replacement for my stock spring?

This EPI Red Secondary Clutch Spring is designed as a replacement part. While it fits the specified CFMOTO models, its spring rate is different from stock and may be chosen for performance tuning rather than a direct stock replacement feel.

Product Details

When you're out on the trail or working your CFMOTO CForce, UForce, or ZForce, you want your machine to respond smoothly when you hit the throttle. This EPI Red Secondary Clutch Spring is designed to help your clutch engage more consistently, especially if you've modified your machine or are looking for a more predictable feel. It's a well-built replacement that helps ensure your power gets to the wheels when you need it.

EPI makes these springs from good quality material, holding them to a tight 5% tolerance for consistency. This means you get a spring that performs reliably, load after load. At 2 1/4 inches, it applies 104.3 kg of load, and at 3 1/2 inches, it's at 81.5 kg. This specific spring rate is often chosen to help tighten up the engagement and provide a more responsive feel compared to a stock spring, especially if you've added larger tires or other accessories that change the load on your drivetrain.
