YOSHIMURA YZ250F ’24-25 RS-12 STAINLESS FULL EXHAUST, W/ ALUMINUM MUFFLER

The adjustments to the Yoshimura spec proved what the 2024 YZ was telling them team was right. The revised RS-12 Signature Series full system added 2.5% max HP and 2.8% max torque over stock.

The RS-12 mufflers have loads of features including a 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 the 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

Proudly designed, developed and made in the USA!
