HOT CAMS offers you this stage 2 camshaft on the exhaust side to fit your YAMAHA YZF 450cc and YAMAHA WRF 450cc. This camshaft has the same position and timing as the original one. However, the opening times have been changed to increase the performance of your motocrosser. During our dyno test, we noticed that the engine had much more torque from start-up and much better mid-range pick-up. It can be fitted to original cylinders or to BIG BORE kits such as ATHENA. Ideal for quickly and easily boosting the performance of your motocross bike.
