The 2004-2008 Yamaha YZF-R1 is an amazing sportbike, but it has a weak point. This generation R1 used a unique high RPM gear-driven race-style flywheel that was known for the magnets coming loose. When this happens stator damage occurs, along with debris in the crankcase. RMSTATOR has developed a direct replacement flywheel for this motor with heavy-duty epoxy and encased magnets to prevent this from happening.
Follow along with RMSTATOR’s Engineer Evan as he installs an RMSTATOR flywheel, stator, and voltage regulator on our 2007 Yamaha YZF-R1. You can easily do this job yourself in your own garage with no special tools.
*The same parts fit the Yamaha FZ1and FZ8 models from 2006 and onwards, with a very similar installation procedure.*
