Stroker Crankshaft 51.0mm 12V Monkey

【KITACO 309-1083500 Stroke Up Crankshaft 51.0mm 12V Monkey KITACO 309-1083500】
This long-stroke crankshaft is essential for stroke-up modifications.
By reducing rotational mass, it achieves excellent power at high RPMs and improved response without sacrificing low-speed torque.
Ultra-high speed precision bearings and timing gear are pre-assembled.
Please note that the shape of crankshafts for Monkey and Super Cub models varies depending on the vehicle type and model year.
When installing a stroke-up crankshaft, always check the shape of the oil pump spindle.
Depending on the shape, the crankshaft may interfere and cannot be installed.
If necessary, please purchase a separate spindle.
