AKRAPOVIC Evolution Line Exhaust System - Titanium/Titanium - KX 250 S-K2MET9-BNTA

If you're running a KX 250 on the track, weight savings and peak power delivery are non-negotiable. The Akrapović Evolution Line exhausts system delivers both—shedding unnecessary mass while unlocking additional horsepower through optimized scavenging and reduced backpressure. Factory-proven across motorcycle racing's most demanding circuits, this system is purpose-built for competitors who demand measurable performance gains.

Constructed entirely from titanium, every component—from the perforated inner sleeve to the conical header tube—has been engineered for durability under extreme conditions. The header tube joint is CNC-milled and secured with high-quality silicon-shielded tempered springs, ensuring precision fitment and reliability. This is the same exhaust trusted by Akrapović's factory racing teams.
