Yamaha YZ Bottom End Kit - Hot Rods - `02-`18. Complete bottom-end rebuild kit for 2002–2018 Yamaha YZ 85 (85cc) models that supplies the major internal components and gaskets needed to refresh the engine’s lower assembly.

This Hot Rods kit packages the crankshaft, main bearing and seal kit, plus a full top and bottom end gasket kit with seals to simplify a rebuild. It saves time by grouping matched components in one box so you won’t have to source multiple parts separately. A stroker crankshaft option is available on some models for riders considering a measured upgrade path. The kit is suitable for experienced home mechanics and professional shops who want a reliable, OEM-compatible replacement set of bottom-end parts without mixing suppliers.
