After receiving feedback from the Westby Yamalube team Yoshimura understood what the Yamaha YZF-R1 needed and have now delivered the Alpha-T 3/4 race system that brings the 998cc R1 come to life. With the Alpha-T 3/4 race system you get a one of a kind blend of sounds from the Yamaha crossplane engine and the Yoshimura Alpha-T muffler.

With the Alpha-T 3/4 system peak horsepower increases by five hp and peak torque is improved by almost five pounds. Great weight savings are realized as well: Over 12 pounds less than stock with the Alpha-T 3/4 Ti system!
