The Triumph brand may be new to the Motocross world, but they are not strangers to building top-quality products and securing race wins. That legacy of performance and reliability is a perfect fit for Yoshimura. 

Yoshimura's now-iconic RS-12 Signature Series full system not only looks stunning on the TF250X but also delivers significant power gains across the entire spectrum. Riders can expect up to a 2.63% increase in horsepower at 11,600 rpm and torque improvements of up to 1.08% at 9,180 rpm.

RS-12 Features and benefits:

• Rubber mounted RS-12 muffler dampens vibration to subframe .
• Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximise capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12's unique profile also provides more clearance for tyre and brake calliper.
  
• Improved performance gains with refined linear power delivery.
• Just like the works systems Yoshimura Factory Racers use, RS-12 systems utilise 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.
• New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters.
• Works-look matte carbon fibre end cap with industry leading design, innovation and detailing as expected from Yoshimura.
• Carbon end cap covers the RS-12 inner cap, thus improving looks, while providing easier service as compared to other sandwich mounting designs most commonly found in the industry.
• Proudly designed, developed and made in the USA!
• Repack Kits, optional Inserts and Spark Arresters are available for all models
