Full Ti System YZ450F 2023-25
$3,659.90
Close cooperation between Akrapovič’s Racing R&D and R&D departments has resulted in an exhaust almost identical to the specifications for the one the Monster Energy Yamaha Factory MXGP Team will be racing with in the 2023 Motocross World Championship season. The tailor-made design fits within the limited space on the motorcycle and is the largest that the space will permit. This allows increased sound silencing to mitigate the impact on the natural environment while also facilitating improved flow for the exhaust gases to make their way from the combustion chamber with as few restrictions as possible.
Constructed completely from lightweight, high-grade titanium alloys, this system offers a weight saving of 20.4% (0.9 kg) over the stock exhaust. Different thicknesses in the sections ensure perfect protection and reduce overall weight, allowing the added strength created by the design to provide enhanced resilience in the most demanding conditions. It offers an increased response through the entire rev range, with the power and torque levels increased by an extra 1.8 kW (2.4 hp) at 10,600 rpm on the in-house dyno and 1.5 Nm at 10,500 rpm in back-to-back tests as recorded against a standard stock exhaust system.
A new profiled surface, which influences the deep, full sound, and an integrated resonance chamber for optimum performance and befitting the sound of an Akrapovič exhaust, are all designed to ensure this system meets FIM noise limits for competition. A special technique was used for imprinting the logo on the surface: there is no sticker or engraving, but a new way of adding the logo. Developed for use on closed-course competition circuits only, it is a simple plug-and-play operation to install, with no remapping needed.
