Yoshimura RS-12 Exhaust System Husqvarna FC450 / Rockstar Edition / KTM 450 SX-F / Factory Edition

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. Yoshimura's 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.

Features:

Developed and tested over 24 months of factory level racing
Aggressive, intelligently designed, asymmetrical shape of the RS-12 allows for maximum muffler volume which helps manage sound, add power and provide more clearance for the rear tire and brake caliper
Improved performance gains and weight reduction
Just like the works systems Factory Racers use, RS-12 systems utilize precision machined joints which provide a superior fit and improve system life and performance
Works-look matte carbon fiber end cap with industry leading design
Carbon end cap covers inner cap mounted design which improves durability and eases servicing as compared to other sandwich mounting designs
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 the 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
