The 2018 Kawasaki Ninja 400 is sure to be a favorite with not only club racers but with those competing in the new Jr. Cup at Moto America rounds this year. This green machine has set the bar high for the competition, and Yoshimura is here to help even more.
Using our race proven Alpha T muffler to shape the power characteristics of the new green machine, our engineers found grunting torque and HP that pulls throughout the range. Power is up with the Alpha T full system 4.8% max HP and 4.2% max torque. Additional gains are made in weight, saving over 6lbs versus the stock complete system. Exclusive Works Finish gives this race system a golden titanium look after a heat cycle, and the sound is purely Yoshimura.
Also available is our black powder coated aluminum muffler bracket that is a necessity if the rider wants to remove the rear pegs to go racing.
Proudly made in the USA!
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
