Honda CRF 450 R Bottom End Kit - Hot Rods - Stroker Crankshaft - `09-`12. This complete bottom end kit contains the primary components required to rebuild the lower end of a 2009–2012 CRF450R in one convenient package.

Built for riders and technicians who want a straightforward rebuild or a stroker crank option where available, the kit includes the crankshaft plus the main bearing and seal kit, and full top and bottom gasket and seal sets.

The stroker crankshaft option (available on select models) provides an alternate rotating assembly choice for custom engine builds while retaining compatibility with the listed model years.
