The revised RS-12 Signature Series full system added 2.5% max HP and 2.8% max torque over stock.
Yoshimura's RS-12 system is proudly designed, developed and manufactured in Chino, California.
NEW YZ250F RS-12 Features and benefits
- 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
- 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, innovation and detailing as expected from Yoshimura.
- Carbon end cap covers an 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
