Akrapovic Evolution Line (Titanium) YZ450F 2026

The collaboration between Akrapovic Racing R&D and the Yamaha MXGP team has produced an ultra-lightweight titanium race exhaust that improves performance across the entire rev range. Its tailored construction maximizes flow and reduces back pressure, increasing engine response and power. Dyno testing shows gains of +1.8 kW (2.4 hp) at 10,600 rpm and +1.5 Nm at 10,500 rpm compared to the stock system. The exhaust is 20.4% lighter, extremely durable, and meets FIM noise limits for competition. Ins
