PROX Clutch Springs Kit for BETA RR 250, RR 300, RR 350, RR 400, RR 450 2009-2019

PROX offers these clutch springs for BETA RR 250, RR 300, RR 350, RR 400, RR 450 2009-2019. The springs push on the pressure plate to clamp the plates together. With heat they lose strength and the clutch starts to slip.

Why replace the clutch springs?

The benefits:

• Stop slipping, especially under acceleration.
• Get a positive clutch back.
• Heavy-duty springs exist for tuned engines (slightly heavier lever).

Why choose PROX?

When should you replace the clutch springs on your BETA RR 350?
