Leaning on many of its bigger sibling's handling and styling cues, the new Honda CRF250R boasts many new features. It's lighter, more agile and is sure to be up to the task of reaching top podium results!

Gleaning everything they could from its big brother on the prior year model CRF450, Yoshimura developed the RS-12 to optimize the power on the new CRF250R to enable it to have the most bottom and mid power and provide maximum overrev to give the best possible power curve for Supercross and Motocross racing.

The RS-12 with its built-in resonance chamber, race-proven craftsmanship and iconic shape provides the best power available for the new Honda CRF while keeping the DB level to acceptable racing parameters and providing great tire and brake calliper clearance.

Jett and Hunter Lawrence used the RS-12 systems during the 2022 AMA Supercross/Motocross championship.

The RS-12 is proudly developed, designed, and made in the USA.

FEATURES

• 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 calliper.
• The unique oval manifold design was created using the FEA process (Finite Element Analysis) and produced using a 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 fibre end cap with industry-leading design and innovative 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
• The 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!
