While other exhaust brands just carried over their Yamaha YZ250F offerings to include 2024 model, on the dyno and track, the new YZ told the Yoshimura team there was more on the table. So their R&D team went to work to optimize the new Yamaha.

The adjustments to their spec proved what the 2024 YZ was telling their team they were right. The revised RS-12 Signature Series full system added 2.5% max HP and 2.8% max torque over stock. This is why Yoshimura develops and tests all of our products!

The RS-12 mufflers have loads of features including our PTF insert system that makes changing inserts a breeze and an optimized muffler shape with added volume and brake caliper clearance.

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
• Repack Kits, optional Inserts and Spark Arresters are available for all models
