Description
One of our most popular systems, the AT2 Race Series for the MT-09 is now available as a Speed Series!
The all-new Speed Series Works Finish system checks all the boxes for looks, sound and performance. This AT2 system, like our Race Series, has the power delivery optimized to perfection. Its also Euro 5 +, dual lambda compatible.
When it comes to performance Yoshimura is squeezing every drop from the Yamaha MT-09's 890cc CP3 engine. Our engineers extracted up to 3.1% more HP @9000 rpm and up to 3.8% torque @6800 rpm from this 890cc triple. Our Integrated Sonic Chamber allows us to boosts power over the stock unit. It also provides the MT-09 a little extra bark all while keeping the new Speed Series full system 49 state friendly, and loosing almost 5 lbs. in the process!
