DESCRIPTION
Unleash next-level performance from your Honda CRF450R or CRF450RX with the Akrapovič Evolution Line Titanium Exhaust System a premium, race-proven system built for riders who demand maximum power, razor-sharp throttle response, and championship-ready durability. Designed specifically for the tight confines of modern motocross and enduro chassis, this system delivers elite performance in the most punishing conditions from deep sand tracks to hard-pack race circuits.
Race-Bred Engineering Meets Titanium Precision
Every detail of the Evolution Line has been meticulously engineered for performance. Constructed from lightweight, aerospace-grade titanium alloys with variable wall thickness for optimal strength-to-weight ratio, this system is 26.5% lighter than stock drastically reducing overall weight for sharper handling and improved agility.
A redesigned profiled muffler not only meets the FIM 109dB sound limit, but also produces a deep, resonant tone that enhances the bike’s single-cylinder pulse without exceeding noise regulations. The oversized muffler body maximizes gas flow and silencing while delivering added strength and long-term durability in extreme conditions.
Real Power Gains You Can Feel
This isn’t just about sound and weight savings Akrapovič backs it up with real-world performance. On the dyno, the Evolution Line delivered:
+1.8 kW (2.5 HP) at 10,300 rpm
+1.5 Nm of torque at 7,900 rpm
The result? Crisper throttle response, a stronger mid-range punch, and enhanced top-end pull giving riders a more connected feel and greater control from the moment they twist the throttle.
