Description
If you’re running your CRF250R or RX on a racetrack with strict noise ordinances, this AKRAPOVIĆ Evolution Line Noise Damper Insert is your compliance solution without sacrificing the performance exhaust system you’ve already invested in.

Install it for race day, remove it for the street, and keep your setup optimized for every scenario.
