Yoshimura R&D of America billet motocross camshaft's are designed here in the USA and then manufactured at Yoshimura Japan to exacting standards. Before the camshaft prototypes are ever sent to Japan, they undergo hours of trials and testing. This is where Yoshimura R&D works to find the perfect balance of power, efficiency, and reliability.

Yoshimura R&D designed the CRF250R camshaft with increased lift and duration to produce a potent curve with mid to top-end power & torque to accompany the power already available on the bottom end. This means when you whack open the throttle out of a corner, you'll get a nice hit off the bottom and an even bigger kick on the top end.

The camshafts are CNC machine ground from the absolute finest quality Billet Bar Stock for the highest degree of strength and precision. After the blanks are machined to size, they are sent to Yoshimura Japan for special metallurgical treatments. The next steps are grinding to absolute specifications, checking meticulously for accuracy, and finally heat-treating the finished camshafts for lasting performance. While the cams are being ground in Japan, the cam sprockets are machined from high-grade Billet and run through thier ISF Process for increased strength, durability, and smoother operation. After final approval, the camshafts are sent back to Yoshimura USA for final packaging and sale.
