Yoshimura RS-12 Exhaust System Honda CRF450R / CRF450RX

The 2025 Honda CRF450R, a bike transformed by significant upgrades, is now poised to deliver an exhilarating riding experience. Impressively, these improvements prompted Hunter Lawrence to select this machine for the concluding segments of the AMA Pro Motocross season. The motorcycle features a completely redesigned chassis, modernized airbox, and an optimized ECU configuration.

The result is the RS-12 Signature Series full system, which elevates the motorcycle's output, offering a 3.7% max horsepower increase and a 1.3% boost in max torque when compared to the stock configuration.
