Fitment: 2021-2023 CRF 450R/RX/RWE The Yoshimura RS-12 and the 2021 Honda CRF 450R—made with one goal to provide the most precision tuned machine in motocross competition. Yoshimura Titanium Full system weight 7.0 lbs. vs Stock Weight 8.3lbs 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 Powered Team HRC Honda's Tim Gajser to his fourth FIM World Championship! 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. Unique oval manifold design was created using FEA process (Finite Element Analysis) and produced using state-of-the-art hydroforming process Improved performance gains, weight reduction and fit when compared to previous generation design Just like the works systems our Factory Racers use, RS-12 systems utilize 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 Works-look matte carbon fiber end cap with industry leading design and innovation end cap detailing as expected from Yoshimura Carbon end cap covers inner cap mounted design improves durability, and eases servicing as compared to other sandwich mounting designs most commonly found in the industry New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance Proudly designed, developed and made in the USA!
