The Hot Rods Complete Bottom End Kit for the 2001 Yamaha YZ 125 includes everything needed for crankshaft installation and a full engine rebuild. The kit features a factory-assembled Hot Rods crankshaft, main bearings, and seals, along with a complete gasket set containing all necessary gaskets and seals. The crankshaft is fully rebuildable with genuine Hot Rods connecting rods and is designed to meet or exceed OEM specifications. Owners can choose between a Heavy-Duty OE replacement crankshaft or a Heavy-Duty Stroker Crankshaft, which increases the stroke length depending on the application. In some cases, modifications to the cylinder head may be required.
