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.
This bike features a 36-liter fuel capacity, giving you the range needed for long stages. The frame design prioritizes weight distribution and rider ergonomics, ensuring control and comfort across challenging terrain. Built on a proven HRC frame, it delivers race-tested strength and handling. Dual fuel pumps, one in each tank, allow for rider-controlled fuel management and provide a backup in case of failure—because reliability is everything.
Our latest upgrades boost both performance and reliability. A 6-speed gearbox replaces the standard 5-speed for better control and flexibility. The custom crankshaft increases engine lifespan and strength, while an added oil cooler keeps temperatures in check under extreme conditions.
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.
Equipped with a Showa A-Kit front fork featuring Kashima coating for smoother action and reduced friction. The rear shock uses an 18mm spindle, providing enhanced stability, durability, and feedback—essential for high-speed off-road performance.
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.
