Description

This kit fits: Yamaha Raptor 660 (2001-2005), Yamaha Grizzly 660 (2002-2008) and Yamaha Rhino 660 (2004-2007).  Double-check our table below to ensure this part will work with your machine.

The Raptor 660 Big Bore Kit includes everything you need to rebuild your top end:  a brand-new 102mm cylinder, 10:1 piston kit, and a high performance gasket set for easy installation right out of the box - no boring or honing required.

Normally, big bore kits increase engine displacement by increasing the cylinder bore size, the piston compression, or both. This kit increases your engine displacement from the stock displacement of 660cc to 686cc, by increasing the bore size from 100 mm to 102mm and the compression from stock specifications of 9.2:1 to 10:1.

The larger water jackets help your new top end cool your engine more efficiently as it produces more power. In fact, our kit offers greater cooling capability for more reliable performance. You don't want to end up with over-heating problems down the road.

Another performance enhancement is the high-compression hardened aluminum piston. It's designed to help your engine keep up with your increased displacement and compression.

All of the parts necessary for a rebuild are included with no modifications needed.

Want more out of your Raptor 660? Of course you do! You’re a DIY gear-head who’s moded more machines than they can count. So take your quad to the next level and increase your machine’s power with our Raptor 660 Big Bore Kit.
