The 2020 Triumph Street Triple is one of the most agile snappy middleweight naked bikes available. This machine is screaming for more so we had to oblige.
The 765cc British engine, derived from power plants being used in the Moto 2 class, has one heck of a linear power delivery, but not one that we could not make better! After a few rounds on the dyno the crew in R&D were confident the AT2 featured slip-on design they came up with would deliver measurable improvements, without upsetting the Triple’s already amazing power characteristics. The sound our AT2 creates for the triple cylinder engine is nothing short of breathtaking. After considering an impressive 8.3 pound reduction in weight after installing the new AT2 slip-on, you win the Triple Crown: weight, power, and sound that will be sure to make everyone in your riding crew jealous!
The AT2 is proudly made in the U.S.A.
