Introducing the newest RS-12 titanium full system for the 2022.5 KTM SX-F Factory Edition/2023 SX-F 450 and 2022.5 Husqvarna Rockstar Edition FC450/2023 FC450 to give the serious racer every advantage possible.
We got to work as soon as we could developing a system that would not only perform better than stock but one that would make the new 450’s more controllable and more connected. Days of dyno and rider testing put our new RS-12 Signature Series exactly where we wanted it. Packing lots of punch for these two 450cc European machines. Concerned about weight? Tipping the scale at 8.1 lbs. this new RS-12 is light!
This new system is the first Yoshimura production motocross exhaust 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 more rider connectivity. Adding 5.9% more peak HP and 6.9% max torque, this RS-12 has all the boxes ticked for what can add up to lots of podiums.
- Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximize capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12’s unique profile also provides more clearance for tire and brake caliper.
- Tuned header resonator for enhanced power characteristics and improved sound
- 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 arresters
- Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
Spark arrestor sold separately.
The RS-12 proudly developed, designed, and made in the USA.
