New Products: Pro Circuit Engine Parts for Honda and KTM Dirt Bikes

CORONA, CA – December 23, 2015 – (Motor Sports Newswire) – At Pro Circuit, we’ve earned our reputation as a premier engine builder by offering our customers only the finest performance parts available. Our newest products are a new performance camshaft and valve springs for the 2016 Honda CRF250R and for KTM riders, we now have improved clutch springs for the ’15 1/2 – 16 KTM 250 SX-F.


Pro Circuit engine components are designed for maximum performance and our new 2016 CRF250R camshaft provides optimal power and torque over OEM while our new high performance valve springs keep the valves in control and operating smoothly at high RPM.

KTM riders will appreciate the increase in clutch life and less slipping with our new Pro Circuit clutch springs for the 2015 1/2 and 2016 KTM 250 SX-F. These springs work well in stock or modified engines and are a must-have for a serious rider.
