Honda CRF 150 R Bottom End Kit - Hot Rods - `07-`21. A complete bottom-end rebuild package that gathers the essential components needed to refresh the lower half of your CRF150R engine in one convenient box.

This kit contains the crankshaft, main bearing and seal kit, plus a complete top and bottom end gasket kit with seals, prepared for model years 2007 through 2021. It’s designed for riders and mechanics who want a direct, reliable way to rebuild the bottom end without sourcing parts individually. A stroker crankshaft option is available on some model variations, and choosing the kit can save time and money compared to ordering separate OEM components.
