Yamaha YZ Bottom End Kit - Hot Rods - Stroker Crankshaft Option Available - `02-`18. A complete bottom end rebuild kit for Yamaha YZ85 (2002–2018) that bundles the core components needed to refresh the engine’s lower assembly quickly and accurately.

This Hot Rods kit arrives with matched components to simplify rebuilding the bottom end: the crankshaft, main bearing and seal kit, plus a full top and bottom end gasket set with all required seals. A stroker crankshaft option is available on some model years for those seeking a different crank configuration. Choosing a complete kit reduces parts sourcing, helps ensure proper fit, and can save time and money compared to ordering individual OEM parts.

• Includes crankshaft (standard; stroker crank option available on select years)
• Main bearings and seal kit included
• Complete top and bottom end gasket kit with all seals
• Designed for Yamaha YZ85 models 2002–2018 (85cc)
