Introducing the newest RS-12 full system from Yoshimura R&D of America for the 2022.5 KTM SX-F Factory Edition/2023 SX-F250 and 2022.5 Husqvarna Rockstar Edition FC250/2023 FC250.
The Austrian 250 engine that is the heart of the KTM and Husqvarna is a brand-new platform for the 2022.5 FE/Rockstar and 2023 machines. Our R&D engineers focused on getting the new powerplant to carry power all the way through the range. Now, the RS-12 provides the racer a much more wider power curve while adding 2.7% max HP and 2.6% max torque. Better than stock, you bet!
This system and the new one we just introduced for the Austrian 450 models are the first Yoshimura production motocross exhausts to incorporate a resonator on the header and in the muffler. This new header resonator unlocks bottom and midrange power to not only make the new Austrian bikes more powerful, but provides additional overrev.
Spark arrestor sold separately.
The RS-12 proudly developed, designed, and made in the USA.
Developed and tested in the heat of over 24 months of factory level racing
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 and fit when compared to previous generation design
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 and innovation end cap detailing as expected from Yoshimura
Carbon end cap covers 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
Proudly designed, developed and made in the USA!
Repack Kits, optional Inserts and Spark Arresters are available for all models
