Takegawa Crankshaft Support Adapter

This crankshaft support adapter changes the crankshaft journal support from two points to three points, reducing wobble and increasing durability at high RPM. The generator of the bike is mounted on the L. crankcase cover, placing the flywheel’s weight on the outside of the crankshaft tip and potentially causing damage. With a patented ball bearing structure, this product provides three-point support for the crankshaft without needing to replace it. Please check your current stock crankshaft before purchasing and note that a special tool is required to remove the flywheel nut. Product specifications may vary due to manufacturer reasons.
