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.
DISCLAIMER: Images shown are a mixture of the current and previous year model.
What HRC’s factory racers want, they get. So can you. Try more low-down torque – 10.7% @ 5,000rpm, with smoother low-down power delivery to drive hard, everywhere.
The CRF450RX uses unique, new damping rates in both the 49mm USD forks and rear shock to deliver absolute compliance and traction over all sorts of ground.
A larger fuel tank extends range. 21-inch/18-inch DID rims allow use of enduro-specific tyres, knuckle guards protect hands and levers while the sidestand is there if you need it for convenient standalone parking.
HRC has also tuned frame ‘feel’ to deliver precise feedback front and rear, with maximum grip and total stability, for maximum control over a special test and any terrain.
3-level Honda Selectable Torque Control (HSTC) and Engine Mode Select Button (EMSB) deliver the engine character and drive you want. HRC Launch Control owns the start.
Reach for it. You know you can. It’s why you ride the CRF450RX. The engine? Amazing. So strong, everywhere. But with smooth delivery that doesn’t wear you out. The chassis? Delivers the feedback for grip and handling control you need while absorbing the big – and small – hits. And it’s ready to do it all day. As are you. Because you ride the CRF450RX. Together you are unstoppable.
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.
The lightweight aluminium frame features a new, factory-rider led rigidity balance – from new steel engine hangers plus 2mm thicker front frame joints and upper shock mount – to produce a stable chassis that finds amazing front-end grip, yet steers razor-fast. Suspension updates include a higher, 56N/mm spring rate for the Showa shock with increased damping. The 49mm USD forks also have new damping settings to match.
New graphics mark HRC’s major input and minimal bodywork allows maximum freedom of movement and easy removal – just what you need for easy maintenance. The 8L plastic fuel tank offers more riding time and there’s a forged aluminium sidestand tucked neatly away. Renthal Fatbars offer comfort and four-way adjustment (for your perfect riding position) and are fitted with knuckle guards to protect hands and levers.
