Yoshimura R&D Of America Announces All-New RS-9 For The 2013 Honda CRF450R
CHINO, CA (October 1, 2012) – Yoshimura R&D of America, the leader in performance, has been synonymous with superior craftsmanship, precision fitment, and impeccable quality for years. Yoshimura R&D is excited to announce a complete performance solution for the new 2013 Honda CRF450R with the introduction of the all-new Yoshimura RS-9 system.
The dual-muffler configuration on the redesigned 2013 CRF450R gave Yoshimura the opportunity to create an entirely new muffler, specifically built for the CRF450R. Yoshimura worked in confidence with consultation from top AMA Pro riders Jeremy McGrath, Justin Barcia, Trey Canard, Eli Tomac, and Justin Brayton, to achieve maximum performance, mass centralization, and optimize rider-usability. Yoshimura R&D was able to achieve all this, while keeping sound levels in check with AMA Regulation.
Beginning with the head-pipe, a 3-stage tapered design results in better power, better throttle response, and usable power delivery. It is also spring mounted for increased durability. The header flows seamlessly into a re-configured tailpipe, where the exhausts gases are separated to each muffler. Yoshimura’s vertical divider splits the exhaust gases more evenly, for smoother flow, which improves mid-top power and throttle response. Divided exhausts gases then reach our new, dual RS-9 mufflers, hence RS-9D. RS-9’s parallelogram-shaped muffler body increases muffler volume over the stock system, resulting in better throttle response and improved noise cancellation. The dual setup enabled us to position the mufflers closer to the bike’s center of gravity (mass centralization) resulting in better handling for the rider. An additional benefit of the mass centralization process was decreasing potential for muffler damage in the event of crash.
The Yoshimura RS-9D not only makes more power and torque possible, but also does it more quietly than single systems. The uniquely sculpted carbon fiber end-caps feature a tunable insert system, able to fine-tune power delivery and decibel levels to rider specifications. The Yoshimura RS-9D systems are AMA 2-Meter Max and Amateur 94dB sound compliant right out of the box.
