The exhaust that propelled Hunter Lawrence the 2023 AMA SX and MX 250 Championships, Jett Lawrence the 2022 AMA MX 250 Championship and both Hunter and Jett Lawrence to the 2022 AMA 250 e/w Supercross, Championships!

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.

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

Customer Reviews (4.6 / 5 · 5 reviews)

Kevin Y. ★★★★★

The fit on my 2024 CRF250R was spot on, no fussing with alignment out of the box. The stainless muffler has a deep, aggressive tone that makes the bike sound like a legit race machine.

Sebastian Z. ★★★★★

Took it to the track the day after install and the mid-range pull is noticeably stronger, especially coming out of sandy corners. The stainless muffler looks sharp and the whole system sounds mean without being obnoxious. It’s louder than stock, but for a race bike that’s exactly what I wanted.

Edward ★★★★★

Bolt-on fit was spot-on for my '23 RX, and the stainless muffler has held up great through muddy weekends. The mid-range pull is noticeably sharper now, and it's not obnoxiously loud at trail pace.
