Yamaha Raptor 660R Top End Refresh Kit

Refresh the top end of your 2002-2005 Yamaha Raptor 660R with this Top End Refresh Kit from REV6. Designed for engines with a serviceable piston, this kit includes a standard bore piston ring kit and top-end gasket kit to help restore compression without replacing the piston.

Replacing the piston rings and gaskets while the engine is apart helps improve sealing, reduce oil consumption, and simplify your repair. Additionally, completing this service before major wear develops can help extend engine life.

When This Top End Refresh Kit Is the Right Choice

Choose this kit when your piston remains within specifications but the rings and gaskets need replacement. However, if your piston also requires replacement, the Top End Rebuild Kit is the better choice.

• Top End Gasket Kit
• Standard Bore Piston Ring Kit

Compatible Yamaha Models
