Some of the features of the new RS-12evo include:
All-new RS-12evo carbon end cap
It was time to enhance the look of the RS-12. Introducing RS-12evo the next level from Yoshimura, represents an unrelenting pursuit of form and function from our R&D engineers at Yoshimura.
All-new Hydroformed Muffler
RS-12evo includes an all new hydroformed muffler design that allows for the most efficient use of the area next to the airbox, subframe and shock creating a custom tailored fit that no others have.
This new sleeve also incorporates a deep draw one-piece resonator further improving durability. Efficiency is one thing, but the sick look of the styling on the RS-12evo muffler is second to none.
Precision Taper Fit
Precision Taper Fit sound inserts are a patent pending system that allows for easy removal and installation of sound inserts and spark arrestors with RS-12 and RS-12evo mufflers.
Hydroformed Header Primary
Improved performance due to exact matching of the oval exhaust port, with an incredible smooth internal transition from oval to round.
Increased durability of this design comes from a reduction in welded connections that results in an improved fit coming from the exact repeatability of hydroforming process.
Header Resonator
Developed in cooperation from countless hours with Honda HRC teams, our header resonator isn't just there for looks, it allows us to maximize power across the spectrum, while enhancing rider connectivity.
Cast Manifold
Benefits include increased strength, durability, easier installation and removal.
CRF450R RS-12evo is designed, developed and made in the USA with the help of Team Honda HRC race teams in the USA, Europe and Japan.
