The Kawasaki Ninja 500 is now ready to head to the race track with our new AT2 Race Series Works Finish full system!

The new 451cc twin-cylinder engine of the Ninja 500 challenged our development team to add power and torque, and they did! Our AT2 responded with 5.7% increase in max hp and 6.1% increase in max torque! That, along with losing 6.3 pounds of weight from the stock system will make any track day rider rejoice!

Our AT2 Race Series full system includes a carbon fibre heal guard and low-volume sound insert INS-20-K for noise-sensitive race tracks.

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