We now have a way to offer an additional crank support for your CRF110 motor. The OEM crank has 3 bearings from the factory - the two main bearings plus another in the clutch cover that supports that end of the crank. The flywheel side is left unsupported until now! We've machined a billet bearing retainer that holds a genuine SKF bearing in to the stator housing which acts as a guide for the custom machined flywheel nut that fits perfectly in to the bearing. This extra support is designed to keep your crank as true as possible when spinning high RPM and riding the rev limiter.
