ThE Akrapovič Evolution Line exhaust for the revised 2024 Kawasaki KX450 models is a complete titanium system that weighs in at a sprightly 1.3kg lighter than the stock system. The headers feature an integrated resonance chamber with an embossed logo, while the end can has a titanium tip and is emblazoned with a new, longer lasting, logo. Power is up, by 2.6hp, and torque has been increased by 2.5Nm at 7500rpm compared to OE figures according to Akrapovič’s dyno. It’s not road-legal, but does comply with FIM noise limits so can be used on circuits and at events. SRP is £1638.
