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.
- Engineered for the demands of the off-road world.
- Aggressive, intelligently designed, asymmetrical shaped RS-12 profile allows maximized muffler volume to help manage sound, add performance, weight reduction and provides more clearance for tire and brake caliper.
- Works-look matte carbon fiber end cap and custom carbon fiber heal guard with industry-leading design, innovation and detailing as expected from Yoshimura.
- New RS-12 end cap design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry.
