Just like the CRF450R, the CRF450RX has a frame and steering geometry developed directly from HRC’s race bikes and features new off-road specific suspension settings so you can go in harder and come out faster. The engine also features new ECU mapping for even smoother torque delivery, controlled by hydraulic clutch. The 3-Level HRC Launch Control gives you options out of the gate whatever your riding ability or experience, and whatever conditions you’re riding in. And once you’ve bossed the start, 3-Level Honda Selectable Torque Control (HSTC) keeps you driving forward.
With the CRF450R MX machine as a base, the CRF450RX already has an advantage and along with its enduro-specific equipment – larger fuel tank, 18-inch rear wheel and sidestand – its twin-spar aluminium frame saves weight and features a factory-rider rigidity balance with super-sharp steering, huge ground clearance and RX-specific suspension settings. The seat unit’s small (and lower at the back) and plastics slim and lightweight. Delivering strong mid-range power, the engine uses new ECU settings for even smoother throttle response and precise delivery. The decompression system minimises stalling and hydraulic clutch is built tough, with light lever load. HRC Launch Control owns the first 100 metres and HSTC manages rear wheel traction.
Quickly flick through the advanced features of this extraordinary motorcycle.
An 8L plastic fuel tank extends riding range. Lightweight and tough, the 21-inch front and 18-inch rear DID wheels are finished in black. To keep it out of harm’s way, the forged aluminium sidestand tucks in close.
To upgrade every aspect of cornering performance, the tapered aluminium twin-spar frame features a rigidity balance with 20% less lateral stiffness. Both top and bottom yokes and swingarm are tuned to match. Steering geometry is racer-sharp.
As the CRF450RX covers all sorts of ground, the Showa suspension has its own spring rate and damping set-up. For perfect balance between front and rear, the 49mm USD coil spring fork’s low-speed shim-stack now delivers firmer compression and rebound damping. Likewise, the shock’s low-middle-high shim stack has been adjusted more compression damping, all the way through.

Riding Mode 1 has a long reaction time with the lightest intervention, useful for reducing wheelspin in tight corners. Mode 2 is a mid-point all-round setting while Mode 3 intervenes quickly and strongly for total control in slippery, muddy conditions.
Developed with direct input from HRC’s racers, 3-Level Launch Control gives you options to make the best start possible whether pro-level rider or beginner: Level 3 (beginner) hits at 8,250rpm, Level 2 (standard) 8,500rpm and Level 3 (Expert) 9,500rpm.

The Engine Mode Select Button (EMSB) alters the engine’s power and torque characteristics. Three maps are available to suit riding conditions or rider preference: Mode 1 is the balanced, standard map, Mode 2 is smooth and Mode 3 all-out aggressive.
Rock-solid reliability has been a big factor in the CRF450RX’s success; a five-hole piston oil jet cools and lubricates while the large-capacity scavenge pump employs twin 12mm drums. As they say to finish first, first you must finish.
The aluminium Renthal Fatbar (839) reduces rider fatigue and improves control. Its position can be adjusted four different ways – to customise the riding position – and comes complete with a Renthal bar pad. Standard-fit knuckle guards protect hands and levers, too.
To help you move freely, the seat is short, light and low at the rear; the sidepanels and radiator shrouds are also slim and the exhaust downpipe tucks close to the engine. And, to simplify maintenance, the plastics mount with just four bolts each side.
The CRF450RX begins life in the same place as the 2022 CRF450R – so it’s heavily based on Tim Gajser’s championship-winning HRC machine. Not a bad place to start. Devour any terrain, at speed. That’s what the CRF450RX is designed for. And it’s a competition-ready machine that defines the control of power. To keep you pushing forward the Showa 49mm USD coil spring fork now features firmer compression damping while the Showa shock – with its super-lightweight steel spring – is also more firmly damped, for perfect balance front and rear. The lightweight twin-spar aluminium frame, swingarm, top and bottom yoke and axle clamps feature factory-rider spec. rigidity balance, with razor-sharp steering geometry and impressive ground clearance.
There’s an even stronger, smoother low-rpm torque feel thanks to new mapping for the PGM-FI and the same amazing power from 4-5,000rpm upwards. A steep injector angle sprays fuel all the way back to the butterfly, for optimum throttle feel and precise delivery. Practicalities matter, too; the large-capacity airbox offers tool-free access to the filter for fast and easy maintenance. When things get hot the hydraulic clutch is built to handle the stress, give a light lever action and deliver consistent lever clearance. The de-compression system automatically manages the engine at low rpm, for stable operation with increased stall-resistance. HRC Launch Control bosses the jump out of the gate while Honda Selectable Torque Control (HSTC) offers 3 modes of power management for ultimate rear wheel traction and drive. And, putting control directly at your fingertips, the Engine Mode Select Button (EMSB) tailors output to conditions.
