Akrapovic - YZ450F
Akrapovic's latest product for the off-road world is a race-inspired Evolution Line (titanium) exhaust for the 2023 Yamaha YZ450F.
"Designed by the Akrapovic engineers working in close collaboration with the Monster Energy Yamaha Factory MXGP Team 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 has been sculpted to fit within the limited space on the motorcycle, but it still follows the principle of being the largest that the space will permit, allowing increased sound silencing and reduced restrictions for improved exhaust gas flow".
Constructed completely from lightweight, high-grade titanium alloys - for a weight saving of 20.4% (0.9 kg) over the standard exhaust - "this system combines performance and durability for the extremes of off-road racing. It features different thicknesses in the sections to ensure perfect protection and to reduce overall weight, allowing the added strength created by the design to provide enhanced resilience in the most demanding conditions.
"It offers a heightened response through the entire rev range and an optimum feeling when the throttle is opened, giving the rider appreciation of control. The power and torque levels have been 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 newly profiled surface enables the sound to meet the FIM noise limits for competition, adding strength and durability to the muffler while delivering a deep, full sound that embraces the balanced pulse of the single-cylinder engine. An integrated resonance chamber optimises performance. This product does not meet emission compliance requirements for street or on-highway use.
