The Akrapovič V-TUV387 is a noise damper insert for the Akrapovič Evolution Line exhaust on the 2025-2026 Honda CRF250R and CRF250RX, developed for racetracks and events that enforce a 109 dB/A sound limit.
This is what gets the bike through scrutineering. Motocross and off-road events test at 109 dB/A as a matter of course, and a full Evolution Line system will not pass without an insert. The damper brings the system down to the required level and lifts out again afterwards, so you are not choosing between a legal bike and a fast one.
One insert covers both the CRF250R motocrosser and the CRF250RX cross-country version, which share the exhaust for the 2025 model year.
Fits the 2025-2026 Honda CRF250R and CRF250RX running the Akrapovič Evolution Line exhaust. Check the sound limit published by your race organisation or venue before your event.
