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 minute our R&D team got this bike on our scanning table we knew the lines of this bike called for the new AT2 slip on system. Its raspy GP tone and its edgy lines are perfect for the UK born Street Triple. A cousin of the Alpha T muffler, our engineers threw everything out, but the kitchen sink at the new AT2 design. New styling cues include an aggressively styled matte finish carbon fiber end cap complimented by a facet-formed tip precisely trimmed using our 3-D laser cutting machine, along with a new matte finish carbon heel guard. All of these edgy high tech cues delivered in our legendary Works Finish make the Street Triple and the AT2 a match made in heaven.
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.
