【SP Takegawa 01-10-0146 54mm Stroker Crankshaft R-Type Monkey Gorilla Dax 50 XR50R/XR70R CRF50F/CRF70F Engine Parts Takegawa】
■Product Description
54mm stroker crankshaft featuring an X-section connecting rod for lightweight yet high strength.

■Detailed Description
●X-section connecting rod
Machined from forged material, adopting an X-section shape.
While achieving weight reduction, sufficient strength is secured, and the diffusion of buckling stress and torsional rigidity are significantly improved.
The surface has a shot finish.
●Reinforced Journal Section
A special bearing with an enlarged inner diameter for the crankshaft's journal bearing is adopted.
This allows the shaft diameter of the journal section, where stress concentrates on the crankshaft, to be increased from 20mm to 22mm, improving shaft strength.
●Product Configuration
Crankshaft, Woodruff key
