Product details

The middle weight class has more options for today's riders, now Triumph enters with the Trident, an entry level 660cc triple with nice power and torque as well as value. The new triple is packed with potential, and we were excited to start development on this new British naked platform. A cousin of the Triumph 675 Daytona motor this new triple was just asking for more power. The stock exhaust is a one-piece unit which required a Race Series full system. Our development team set out to develop the Trident with the AT2, our newest high performance muffler. The system is part of our Race Series lineup, which means it's made to be used on a closed course. Perfect, this bike will be a GREAT track day/race day bike! The AT2 simply looks striking on the new Trident. We don't know how else to put it but the Race Series AT2 system with our exclusive Works Finish completely transformed this triple. The new three cylinder 660cc engine screams with excitement with our new system! Max HP is up 6.9% and max torque is up 1.3%. Some of our secret sauce is in the collector, where we were able to incorporate a specially designed pre-muffler that enhances the power and adds a very unique exhaust note to the all-new British Trident. The weight savings is substantial, dropping almost half the weight of the stock system, the AT2 Works Finish full system coming in at a nice 9.1lbs. This bike on the track will be a blast now thanks to the AT2 full system. With lighter weight making this already light machine handle and with enhanced power throughout the power spectrum, our AT2 full system will be the benchmark for racers worldwide. The AT2 is proudly developed, designed and made in the USA. FOR CLOSED COURSE COMPETITION ONLY; NOT INTENDED FOR STREET USE If you're looking for that competitive edge, look no further than our Race Series. These exhaust systems are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide. New Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use. • Contemporary Satin/matte finish • Uniform heat coloration • Increased fatigue strength • Increased scratch and stain resistance This product was designed to fit on a standard equipped motorcycle, as delivered from the factory. OE and aftermarket accessories not found on a bike as delivered from the factory may not be compatible with this product. Attention international customers: This product was designed and tested to be compatible with vehicles in the U.S. marketplace only. Compatibility, including fitment and performance, may vary by marketplace.
