Akrapovič’s latest product for the off-road world is an all-new Evolution Line (Titanium) exhaust for the 2024 Kawasaki KX450 and KX450X models. Created through close collaboration with the Akrapovič Racing Department, this complete exhaust is an innovative design that closely follows the systems used at the highest level of competition and represents the latest creation in a new generation of Akrapovič exhaust systems for off-road motorcycles.
Constructed from lightweight titanium, the system is 29.8% (1.3 kg) lighter than standard stock and features headers with an integrated resonance chamber and a debossed Akrapovič logo. New technology has been developed directly from Akrapovič’s involvement in motorsports, with a special technique for imprinting the logo on the muffler outer sleeve, which is now bigger and in a white and red colour combination. This technology provides a higher temperature threshold, with greater durability and longer life for a product that will be used in the toughest conditions. This final configuration for the exhaust for the 2024 Kawasaki KX450/KX450X has been chosen from a number of prototypes, following dyno runs and full evaluation on a motocross track by a professional Akrapovič test rider. One of the aims was to enhance power and torque, and this has been achieved with increases of 1.9 Kw (2.6 hp) at 7,500 rpm and 2.5 Nm at 7,600 rpm when compared to a standard stock exhaust and tested on the Akrapovič dyno. Targeted for use on closed-course competition circuits only, this exhaust meets the current FIM noise limits while delivering a deep racing sound, showcasing the pulse of the bike’s single-cylinder engine. No remapping is needed, and it is a simple plug-and-play installation.
