Yoshimura Full System CRF450R/RX 2021 RS-12 FS-TI-TI

– 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.
– 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 arrestors
– 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!
