HOT CAMS offers you these stage 1 camshaft to equip your motocross YAMAHA YZF 450cc. This pack includes the exhaust and intake camshaft. This camshaft has the same place and 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
