CRF450R/RX 2021-2024 YOSHIMURA RS-12 TITANIUM FULL EXHAUST, W/ TITANIUM MUFFLER
In our never ending pursuit to craft the very best exhaust system, Yoshimura introduces the latest titanium RS-12 system for the 2023 Honda CRF450R.
With the latest engine spec, our engineers wanted to get the best most usable power from this new model.
This new system has been developed with and is the closest thing to what 5x World Champion Tim Gajser, Mitch Evans, Ken Roczen and Chase Sexton have been using to grab holeshots and win races. By increasing the resonator in the RS-12 muffler by 50cc (a 14% increase) and adding a second resonator to the header, engineers were able to unlock some insane usable power from this new and improved system.
Easier power delivery
Smoother frontside torque
Allows the rider to ride in an higher gear, thus freeing up suspension.
Less rider fatigue
Made with the premium grade Japanese titanium tubing, this new system adds 5% max hp and 6.5% max torque to the new engine spec with its smaller throttle body and different ECU settings.
NEW 2023 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 and weight reduction.
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.
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, thus 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!
