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.
