HRC has made the 449.7cc Unicam engine even more potent – and usable. Narrower intake ports, a longer air funnel and smaller, 44mm diameter throttle body deliver higher-velocity gas flow to create the extra low-down torque. New valve timing (taken straight from Tim Gajser’s #243 MX machine) and ECU settings for the injection and ignition ensure smooth power and precise response.
Collectively, the electronics package is designed to put absolute control in the riders throttle hand. HSTC keeps the rear wheel driving with 3 adjustment levels to deal with anything from tight corners to slippery mud (you can turn it off, too). The EMSB alters power and torque, from all-round to smooth, to all-out aggressive. And HRC Launch Control hits at 8,250, 8,500 and 9,500rpm for the perfect jump from the line.
The Honda 450 RX Rally features a robust 6-speed gearbox, built for the demands of rally racing. Its wide-ratio setup delivers smooth, precise shifts and optimal power across all terrain—whether you’re flying over desert straights or navigating rocky climbs. Tuned for performance and made to endure, it’s the gearbox you can count on when every second matters.
The perfect balance of stiffness and strength is achieved through components developed in collaboration with XTRIG and Honda. For added stability and control in demanding conditions, the bike also features a high-performance steering damper.
The suspension system is equipped with custom hydraulic damping settings and springs tuned with varying stiffness levels (K) for optimal performance. The front fork features enlarged titanium stanchions with a low-friction Kashima coating, while the rear shock uses a titanium-coated piston rod to minimize friction and enhance responsiveness.
The Akrapovič exhaust system is more than just a component — it’s a critical upgrade to the Honda Rally bike. Crafted from lightweight titanium and engineered for extreme durability, it delivers maximum power output, razor-sharp throttle response, and a deep, aggressive tone. Whether tearing through dunes or climbing rocky trails, Akrapovič ensures the engine breathes better, runs cooler, and performs at its peak when every second counts.
