Yoshimura Works Alpha Street Slip-On Exhaust Yamaha R1 / R1M / R1S

The Yoshimura Alpha Slip-On Exhaust's styling, fit and finish are the result of combining decades of hands on racing experience, state-of-the-art materials with the latest in digital design capabilities. One look at an Alpha Exhaust and you know it’s something special! The Works Finish is not a coating, but a media blast finish using Yoshimura's own special recipe of ingredients. The result is a stainless steel exhaust that after it goes through a heat cycle on the motorcycle, takes on unique coloring that looks much like those works components Yoshimura's factory racers use.

  • Unrivaled fit and finish due to improved production tolerances
  • Optimized for maximum flow and improved ground clearance
