For 2018 Yamaha made some major refinements to the already potent YZ450F. Adding to the usable and tractable power is how we make the new YZ450F even better.

Now there can be more power to rip holeshots, yet making the bike user friendly at the end of the moto when your right hand gets a little frisky.The new Yoshimura RS-4 Signature Series full system adds 2.8% more h.p. and 1.4 ft-lb. more torque to give the rider better, more linear throttle response.
