The mighty Yamaha YZ450F is practically all new for 2023 and ready to inspire new MX champions everywhere.

Lets get right to it...the stock system on the Yamaha YZ450F was hard to improve, but Yoshimura did! The magic of the right tube diameter, right length then their RS-12 was called in to do the work that it was designed to do...perform! Adding power and torque everywhere across the spectrum of the new YZ450 wasn't easy but it was accomplished. Max HP is increased by 8% and max torque is bumped an incredible 13%!

The new RS-12 system unlocked some key power in the right places. The lower and mid RPM range is really enhanced while not disrupting the handling characteristics on the new YZ chassis. Riding with this new added power really made testing the new system a fun project.

RS-12 Features and benefits:

  • 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 our 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
