DHM Fourth Crank Bearing Support System - CRF110 Tools 5mm with 5mm valve stemWe now have a way to offer additional crank support for your CRF110 motor. The OEM crank has three bearings from the factory the two main bearings plus another in the clutch cover that supports that end of the crank. The flywheel side has been left unsupported until now! We've machined a billet bearing retainer that holds a genuine SKF bearing into the stator housing, which guides the custom machined flywheel nut that fits perfectly into the bearing.
