All-New 2021 Honda CRF450R/RX RS-12 Features and benefits:

  • Developed and tested in collaboration with HRC Honda Racing, World Champion Tim Gajser and engineers the new RS-12 is ready for the race track and trails.
  • Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximize capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12's unique profile also provides more clearance for tire and brake caliper.
  • Tapered muffler body inlet design of RS-12 enables the system to be pushed forward in the new Honda chassis thus helping with weight centralization without sacrificing performance.
  • Unique oval manifold design was created using FEA process (Finite Element Analysis) and produced using state-of-the-art hydroforming process
  • Improved performance gains with refined power delivery
  • Just like the works systems our Factory Racers use, RS-12 systems utilize a precision machined joint. 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 arrestors.
  • Works-look matte carbon fiber end cap with industry leading design, innovation and detailing as expected from Yoshimura.
  • Carbon end cap covers the RS-12 inner cap, 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!

    Very nice article and very nice motorcycle honda has made again. I have always had a yoshimura system on my hondas but.. but.. sources in Florida are confirming that non powerhouse dealers will only be receiving one of the 21 crf450rs and powerhouse dealers sources are claiming it wont be available until the end of October and will be going to the first name on the pre deposit list. Hopefully yoshimura will have customers with that year bike to sell product to or abunch of us don't have a yoah system just laying around because it doesn't fit anything in our garage and no 21 crf450r available. Fingers crossed sources are not correct but so far nobody has a release for the public to purchase. Bbbbrrrrraaaaapppp on friends and good luck please comment if any solid official release news becomes available
