The RM STATOR RMS120-107942 heavy-duty flywheel rotor is a reliable replacement for the original equipment flywheel on select Yamaha YFZ450R ATVs. Designed to OEM specifications, this rotor provides precise fitment and dependable performance for repairs, maintenance, or restoration projects. It is engineered for direct installation on 2009–2017 Yamaha YFZ450R models, including the 2009 YFZ450R SE.
RM STATOR improves durability with high-temperature epoxy that is stronger than typical OEM bonding material. This helps reduce the risk of magnet detachment during demanding engine operation. The rotor also features high-grade steel capping to protect the epoxy from harsh additives found in motor oil. If a magnet were ever to loosen, the protective sleeve is designed to help keep it contained and away from the stator.
Each RM STATOR RMS120-107942 flywheel rotor is precisely balanced to help minimize crankshaft vibrations and support longer engine component life. Its heavy-duty construction makes it an excellent alternative to a worn or damaged factory flywheel while maintaining the fit and functional requirements of the original application.
