The Akrapovič Evolution Line S-H2MET13-FDHLTA is a complete titanium exhaust system for the 2022-2024 Honda CRF250R and CRF250RX, replacing the entire stock header and silencer with Akrapovič's flagship motocross system.
It also fits the 2022 CRF300RX, but that application requires remapping. Worth knowing before you order: on the 250 it is plug-and-play, on the 300 it is not. If you are running a CRF300RX, budget for the map as part of the job.
This is a full system, header and muffler both replaced. On a 250 four-stroke the header is doing most of the restricting, so a slip-on alone leaves the majority of the available power unclaimed — which is why the Evolution Line exists as a complete system rather than a canister. Titanium throughout takes real weight off a bike that gets physically thrown around for thirty minutes at a time.
Closed-course competition use only. No street homologation, and not a spark-arrester system for USFS or BLM land.
Fits the 2022-2024 Honda CRF250R and CRF250RX, and the 2022 Honda CRF300RX with remapping. Closed-course competition use only.
