BRAND NEW For the Honda CRF450R / RX 2025-2026 Full Titanium Tailor-made to fit the limited space available within the motorcycle, this system combines performance and durability for extreme conditions and the rigors of off-road racing. Constructed from lightweight, high-grade, premium titanium alloys, with different thickness in the sections to ensure perfect protection and to reduce overall weight, the system is 26.5% lighter than the stock exhaust. A new profiled surface influences the sound to meet the 109dB FIM noise limits for competition, and it adds strength and durability to the muffler while delivering a deep, full sound that embraces the balanced pulse of the single-cylinder engine. The muffler is the largest possible for the space available.
