Specs At A Glance

Good To Know

Q: Is this an original Yamaha part? A: No, this is a Wiseco piston, crankshaft and gasket set made for the Yamaha Raptor 660. It is an aftermarket rebuild kit, not an OEM Yamaha product.

Q: Do I need to measure anything before ordering? A: Yes, confirm your cylinder is still at the standard 100.00mm bore before buying this kit. If the cylinder has been bored oversize, a different piston size will be required.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
