After over three years in development and testing, Yoshimura is pleased to announce the RS-12 is here! With the help of incredibly talented factory sponsored athletes, technicians, devoted engineers and a will to raise the bar, the RS-12 has now arrived.
Just like the works systems Yoshimura 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.
Yoshimura considered all the details when it came to the RS-12. One look and you can see it's like nothing else on the market. As you get closer you will notice the details in every place on this new dirt bike system, from the matte carbon fiber end cap with decal inlays to the precise machined joints, this system is next level.
- 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, weight reduction and fit when compared to previous generation design.
- 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 U.S.A.!
- Repack kits, optional inserts and spark arresters are available for all models (all sold separately).
Yoshimura Exhaust Series Descriptions:
Enduro Series: In the mid 90's Yoshimura didn't go to the dirt; the dirt came to Yoshimura. Enduro Series systems are an evolution of Yoshimura's early off road efforts crafting off-road exhaust systems. The Enduro Series are all equipped with U.S.F.S.-approved spark arrestor, forest-friendly noise levels, and are tailpipe emissions compliant. (CARB/EPA tail-pipe emissions compliant; all applications are marked with appropriate EPA noise emissions labels.)
Race Series: If you're looking for that competitive edge, look no further than Yoshimura's Race Series. These exhaust systems are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide. FOR CLOSED COURSE COMPETITION ONLY; NOT INTENDED FOR STREET USE.
Signature Series: Introducing Signature Series by Yoshimura - an offering of exhaust systems that a dealer can install with confidence. The Signature Series lineup is the answer for today's dealer who is faced with a challenging marketplace. The applications for the Signature Series line cover the entire powersports spectrum, including many off-road applications. Everyone of Yoshimura's Championship Winning Motocross exhaust systems and nearly all of the ATV / Side-by-Side applications are all members of the Signature Series Family. All Signature Series components are tested, documented, and marked as required by federal and state regulations. (CARB/EPA tail-pipe emissions compliant; all applications are marked with appropriate EPA noise emissions labels and certified by an independent laboratory for EPA noise compliance.)
