Complete Bottom End Kits

Description

The Hot Rods Complete Bottom End Kit provides everything needed for a full crankshaft installation and engine rebuild. It includes a factory-assembled Hot Rods crankshaft, main bearings, seals, and a complete engine gasket set. The crankshaft is built to OEM specifications and is completely rebuildable with genuine Hot Rods connecting rods. Owners can choose between a Heavy-Duty OE replacement crankshaft or a Heavy-Duty Stroker Crankshaft, which increases stroke length depending on the application. In some cases, cylinder head modifications may be required. This kit ensures high performance and reliability for Yamaha YZ125 models from 2005 to 2014.
