06+ Honda TRX450R 500cc Big Bore Top End Rebuild Kit

-101mm CPI Cylinder
-101mm Custom 14:1 CP Piston *(Please see fitment note)*
-101mm Cometic Top End Gasket Kit

This kit is for a good duner or drag race combination. This kit will work with all Stock Stroke Applications, and several stroker crankshaft options. We recommend using a Carrillo Rod Crankshaft with this top end kit. Head Porting, Camshafts, Intake and Exhaust Modifications, etc. are not required, but are highly recommended to get them most out of the engine combination.

This Cylinder does not require crankcase boring to fit the cylinder skirt.

*Please Note: Piston may require clearance work to clear the Oil Squirter.*
