YZ450F 2023-24 YOSHIMURA RS-12 STAINLESS FULL EXHAUST, W/ ALUMINUM MUFFLER
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 we did! The magic of the right tube diameter, right length then our RS-12 was called in to do the work that it was designed to do...perform! Adding power and torque everywhere across the spectrum of the new YZ450 wasn't easy but it was accomplished. Max HP is increased by 8% and max torque is bumped 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 while not disrupting the handling characteristics on the new YZ chassis. Riding with this new added power really made testing the new system a fun project.
NEW YZ450F RS-12 Features and benefits
Aggressive, intelligently designed, asymmetrical shaped RS-12 profile allows maximized muffler volume that helps manage sound, add power and provide more clearance for tire and brake caliper.
Improved performance gains
Just like the works systems our Factory Racers use, RS-12 systems utilize precision machined joints. 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.
Works-look matte carbon fiber end cap with industry leading design, innovation and detailing as expected from Yoshimura.
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.
New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arrestors.
Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
Repack Kits, optional Inserts and Spark Arresters are available for all models
Proudly designed, developed and made in the USA!
