HOT CAMS offers you this camshaft stage 2 exhaust side to equip your motocross YAMAHA 450cc. This camshaft rep makes the same place and the same timing as the original one. However, the opening times have been changed to increase the performance of your motocross. During our dyno test we noticed that the engine had a lot more torque from start up and a much better mid-range pick up. 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
