The powerful CP4 crossplane engine used in the Yamaha R1 also powers the MT-10. That makes this hyper naked bike scream with excitement, making it an easy target for us here at Yoshimura R&D.

We utilized our Works Finish AT2 muffler with carbon fiber heel guard that compliments the design of the MT-10. Available in two options: AT2 Race Series 3/4 system (eliminates the CAT using the stock header) and a Street Series slip-on (retains the CAT).

Our AT2 Race Series 3/4 system makes incredible power throughout the power spectrum, adding even more excitement on the race track with this 998cc crossplane CP4 engine. Our AT2 adds even more torque and HP to the already powerful YZF-R1 platform Max HP is up 2% over stock while max torque is up 1.7%. Weight is significantly reduced as well, our 3/4 system helps the MT-10 lose over 9 lbs. from stock! And the exhaust note you get when using the AT2 Yoshimura muffler is second to none.

Yoshimura's AT2 systems proudly designed, developed and manufactured in Chino, California.

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.
