Honda CRF450RX
The new CRF450RX has a boosted low rpm torque output and HRC factory rider-specification chassis. And it’s cross-country ready with enduro-specific equipment – larger fuel tank, 18-inch rear wheel and sidestand – as well as unique engine mapping and suspension set-up. It’s our ultimate off-road tool – and ready for anything.
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.
