Yoshimura RS-12 Exhaust System Honda CRF300L / Rally

The Yoshimura RS-12 Race Series Exhaust System elevates the Honda CRF300L and CRF300L Rally, offering enhanced power, reduced weight, and the distinct Yoshimura sound. Engineered in Chino, California, and honed by CRF expert Ari Henning, it meticulously refines Honda's 300cc single for improved agility, strength, and responsiveness across all terrains.

Features:

  • Aggressive, intelligently designed, asymmetrical shape of the RS-12 allows for maximum muffler volume which helps manage sound, add power and provide more clearance for the rear tire and brake caliper
  • Improved performance gains and weight reduction
  • Just like the works systems Factory Racers use, RS-12 systems utilize precision machined joints which provide a superior fit and improve system life and performance
  • Works-look matte carbon fiber end cap with industry leading design
  • Carbon end cap covers inner cap mounted design which improves durability and eases servicing as compared to other sandwich mounting designs
  • New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arrestors
  • Tapered muffler body inlet design of the RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance
  • Proudly designed and made in the USA

Weight:

  • Stock full system: 12.3 lbs.
  • RS-12 full system: 9.0 lbs.
