Wössner Piston Rings Set Ø50mm for SUZUKI RM 80, TS 80 ER, TS 80 X and YAMAHA YZ 80 1980-1992

WOSSNER offers this piston ring set for SUZUKI RM 80, TS 80 ER, TS 80 X and YAMAHA YZ 80 1980-1992. Rings are thin steel bands sitting in the piston grooves. They press against the cylinder wall to hold compression and scrape oil.

Why replace the rings?

The benefits:

• Regain compression and power.
• Reduce oil consumption and smoke.
• A cheap fix when piston and cylinder are still within spec.

Why choose WOSSNER?

Wössner has forged its own pistons since 1994: Molykote-coated skirt to reduce friction and ease running-in, kit supplied complete with rings, pin and clips.

When should you replace the piston rings?

Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.

Recommended hours for a top-end rebuild (manufacturer recommendation for the Suzuki RM 80 / RM 85):
