Yamaha Raptor 660R Top End Rebuild Kit

Rebuild the top end of your 2002-2005 Yamaha Raptor 660R with this Top End Rebuild Kit from REV6. Designed for engines that need a new standard bore piston, this kit includes a standard bore piston kit and top-end gasket kit to help restore compression and dependable performance.

Replacing the piston and gaskets together helps simplify your rebuild while ensuring the top end is properly sealed during reassembly. Additionally, installing fresh components while the engine is apart helps reduce future downtime.

When This Top End Rebuild Kit Is the Right Choice

Choose this kit when the original piston is worn or damaged and requires replacement. However, if your piston remains within service specifications, the Top End Refresh Kit provides the piston rings and gaskets needed for a lighter repair.
