HOT CAMS offers you these camshaft stage 1 to equip your motocross YAMAHA WRF 450cc and YAMAHA YZF 450cc. This pack includes the exhaust and intake camshaft. These camshafts are in the same place and with the same timing as the original one. However, the opening times have been taken back to increase the performance of your motocross. During our dyno test we noticed that the engine had much more torque from start up and a much better mid-range recovery. It can be mounted on an original cylinder but also the BIG BORE kit like the ATHENA for example. Ideal to increase quickly and easily the performance of your motocross. Contractual photo to come
