RS-12 Stainless Full System for the all new 2023 Yamaha YZ450F
The mighty Yamaha YZ450F is practically all new for 2023 and ready to inspire new MX champions everywhere.
Lets get right to it...the stock system on the Yamaha YZ450F was hard to improve, but Yoshimura did it! Adding power and torque across the spectrum wasn't easy but it was accomplished. Max HP is increased by 8% and max torque is bumped up by an incredible 13%!
The new RS-12 system unlocked some key power in the right places. The lower and mid RPM range is really enhanced with no impact on handling.
Other highlights of the RS-12 system are the machined joints on the key tube junctions to insure a good clean interface between joints. A built in resonator chamber on the muffler, a matte carbon fibre end cap and a PTF low volume sound insert completes the RS-12.
