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 we could from its big brother on the prior year model CRF450, we developed our 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.

Our 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 caliper clearance.

Jett and Hunter Lawrence will be using our RS-12 systems to try and capture the 2022 AMA Supercross titles and defend the AMA 250cc Motocross championship.

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