Honda CRF 450 R Bottom End Kit - Hot Rods - `09-`12 is a complete bottom-end rebuild kit designed for 2009–2012 Honda CRF450R models. It packages the core components needed to rebuild the crankcase and get the engine back to reliable operation.

This kit includes the crankshaft, main bearing and seal kit, plus a full top and bottom end gasket kit with seals — everything required to tackle a bottom-end rebuild in one box. A Hot Rods stroker crankshaft option is available on some models for riders looking for a different displacement profile. Using a single, matched kit saves the time of sourcing individual parts and helps reduce fitment mismatch during reassembly.
