The current generation Kawasaki KX450 has won over a lot of riders with its balanced chassis and predictable power delivery. We felt there’s still more on the table for improvement, enter our new RS-12. With countless hours of track and dyno testing, the KX450 responded well to our RS-12 with crisp and clean usable power that is up across the entire rpm spectrum. The result, max HP was up 9.6% and torque was up as well at 5.6%. Yoshimura RS-12 will improve your experience on the green machine and decrease dB level from stock noise levels. Just what the doctor ordered.
We considered all the details when it came to the RS-12. One look and you can see it's like nothing else on the market. Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance. Carbon end cap covers an inner cap mounted design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry. As you get closer you will notice the details in every place on our new dirt bike system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system takes it to the next level.
