Upgrade your KLX140 engine with the TBparts +6mm Stroker Crankshaft. This is a high quality forged crankshaft designed to deliver major power and torque gains throughout the entire RPM range while maintaining excellent reliability.

The crank features smooth edge counterweights for improved performance and reduced stress points along with a heavy duty DIRECT REPLACEMENT flywheel bolt with a 12mm head for added strength and easier servicing.
