At Yoshimura we never stop improving. The Triumph Street Triple has received substantial updates from its predecessor, with its new 765cc inline three cylinder power plant and aggressive styling, this bike was destined for Yoshimura power.

Introducing our Alpha T slip-on for the Triumph Street Triple. Not only does our Alpha T improve performance in horsepower and torque over the stock muffler, the exhaust note the Alpha T slip-on makes is nothing short of amazing! Installing our Alpha T puts the Street Triple on a diet too, helping it shed 9.3 pounds!
