HOT CAMS offers you this camshaft to equip your motocross YAMAHA YZF 400cc, YAMAHA YZF 426cc, YAMAHA WRF 426cc, YAMAHA WRF 400cc. This camshaft has the same place and the same timing as the original one. The opening times have been taken back to increase the performance of your motocross. During our test on the dyno, we noticed that the engine had much more torque from the start and a much better recovery at mid-range. It can be mounted on an original cylinder, but also the BIG BORE kit like the ATHENA for example. Ideal to quickly and easily increase the performance of your motocross. Contractual photo.
