Product details

New RMSTATOR heavy-duty flywheel rotor for Yamaha 450cc ATVs is a well-priced solution to problems with the OEM flywheel, and an excellent alternative to all the mechanical troubles you can encounter with a repair.

Features:

Built to OEM size. Fits precisely in your ride: install it and forget it.
Improved epoxy. Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment.
High grade steel capping. Prevents harsh additives in motor oil from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator.
Precise balancing. Eliminates crankshaft vibrations for longer engine longevity.
Shop with confidence. Two year warranty. All products are tested.

Exterio r Diameter: 110 mm
Interior Diameter: 99 mm
Interior Diameter Center Housing: 30 mm
Exterior Diameter Center Housing: 33 mm
Thickness (exterior): 31 mm
Thickness (interior): 38 mm

Solid steps show periods confirmed by the store’s change-only price history and completed crawl record: if the price had changed at a check, another point would appear. Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
