2024 Honda CRF450RX Dirt Motorcycle Review Specs Price

The 2024 Honda CRF450RX Dirt Motorcycle is highly versatile, feeling at home on tight GNCC woods sections and on fast WORCS or GNCC courses. Closely related to the motocross-focused CRF450R, the RX keeps an aggressive, agile personality but is purpose-built for closed-course off-road racing with a dedicated ECU and new suspension settings, an 18-inch rear wheel, an aluminium side stand, a large 2.1-gallon fuel tank, and hand guards. Chosen by many off-road racers, including the SLR Honda and JCR Honda teams, its race-winning speed and proven reliability are repeatedly demonstrated in the most challenging conditions of off-road competition.

Imagine the ideal dirt bike that blends factory-level moto power, agility, and precision with the finesse needed for off-road terrain: the 2024 Honda CRF450RX Dirt Motorcycle. We took all the significant upgrades from the 2024 CRF450R and added targeted engineering updates to create the perfect off-road partner. You get stronger low- and midrange torque from revised ECU and fuel-injection settings, plus easier usability from a wide-ratio five-speed transmission.

You also benefit from Honda Selectable Torque Control, which lets you tailor traction for any situation. A lightweight chassis, an 18-inch rear wheel, and specific suspension tuning are all designed to tackle every surface you meet. Finally, Honda’s long-standing quality and durability complete the package, making the 2024 Honda CRF450RX Dirt Motorcycle the real deal for serious off-road riders.

2024 Honda CRF450RX Dirt Motorcycle – Features and Specs

Aluminium Twin Spar Frame

HRC also refined the frame’s feel to deliver precise front and rear feedback, maximum grip, and rock-solid stability, giving you confident control in special tests and across any terrain.

Performance You Have Complete Control Of

The 3-level Honda Selectable Torque Control system and the Engine Mode Select Button allow you to choose the exact engine character and drive you want, while HRC Launch Control helps you nail the start every time.

High-Quality Engineering Built To Endure

The engine is engineered for long-term durability. It has a five-hole piston oil-jet cooling and lubrication system and a large-capacity scavenge pump using twin 12 mm drums; new graphics and an HRC logo also celebrate the deep connection between racing and development.

Enahnced Torque and Low-Down Power For Relentless Drive

HRC’s factory racers asked for more drive, and you get it too, with a 10.7 per cent increase in torque at 5,000 rpm and a smoother low-rpm delivery that helps you accelerate hard everywhere.

Unique Showa Suspension Set-Up Gives Supple Off-Road Control

Unique new damping settings in the 49 mm USD forks and the rear shock provide compliant suspension action and dependable traction across mixed off-road surfaces.

Equipped To Run Hard and Fast

A larger fuel tank extends your range, 21-inch and 18-inch DID rims accept enduro-specific tyres, hand guards protect your hands and levers, and the side stand offers convenient parking when you stop on the trail.

Unstoppable

Reach for your goals because you know you can achieve them on the 2024 Honda CRF450RX Dirt Motorcycle. The engine feels strong across the revs yet delivers power smoothly, so you do not get fatigued. The chassis gives the feedback, grip, and handling control you rely on while soaking up big and small hits, and it is ready to do it all day, just like you.

Engine / Drivetrain

The 2024 Honda CRF450RX Dirt Motorcycle engine supplies outstanding bottom-end and midrange torque with a linear, manageable delivery even as you tire, while top-end power remains excellent; lubrication is handled by a five-hole piston oil jet and a dual 12 mm drum scavenge pump.

Cylinder Head

The Unicam cylinder head places the de-compressor counterweight on the left end of the camshaft to stabilize combustion at very low rpm and provide strong yet controllable power on corner exits while resisting stalling. Engineers followed Team Honda HRC’s direction by optimizing the cam profile for low-end torque, and the thin-wall magnesium head cover keeps weight low.

Intake

A downdraft intake layout delivers efficient power, and a large 4.1-liter clean-side air boot helps create strong low-rpm torque; HRC feedback led to a 44 mm throttle body for smooth low-speed delivery, while a narrow intake port and long air funnel boost low-end torque and crisp response; the airbox is reached by removing a single side-panel bolt, and the 60-degree injector angle sprays to the back of the butterfly to cool the upstream intake path for maximum efficiency and torque feel.

Exhaust

A centrally located, straight, oval exhaust port improves flow and torque, and the header and muffler sit close to the centerline for a slim profile that aids rider movement; the A6061-T6 aluminum muffler adds impact resistance and saves weight, and a dual-resonator design optimizes power while keeping noise down.

Clutch

A hydraulic clutch with eight plates and a generous volume offers strong durability, minimal slip, and a light lever pull.

Electronics

A gear-position sensor enables three specific ignition maps—one for first and second, one for third and fourth, and one for fifth—while Standard, Smooth, and Aggressive ignition modes can be chosen via a new handlebar switch so you can quickly match power to preference or course conditions.

Chassis / Suspension

Heavy components are centralized and placed low to sharpen cornering without losing high-speed stability, while squat under acceleration and pitch under hard braking are minimized.

Frame / Swingarm / Subframe

The frame uses narrow main spars with optimized reinforcement ribs behind the pivot plate, resulting in a low frame weight of just 18.5 pounds. Rigidity is tuned so the suspension moves freely without binding, which improves stability and bump absorption. The simple subframe weighs only 2 pounds, and the narrow swingarm gives extra rut clearance with rigidity set for maximum rear traction and cornering confidence.

Suspension

The Pro-Link rear suspension uses a Showa shock with right-side adjusters and an ultra-light steel spring; the optimized frame rigidity lets the shock move freely to reduce harshness while still providing support for big hits and performance in ruts; up front, a 49 mm inverted Showa coil-spring fork with a gas-liquid separation structure is matched to the shock settings for balanced handling, and the triple clamps deliver an ideal rigidity balance for accurate feel through corners.

Wheels

Black D.I.D rims provide durability and style, petal-style brake rotors effectively manage heat, a low-expansion front brake hose maintains strong feel and consistent stopping, and Dunlop AT81 tires supply versatile off-road traction.

Design

Slim bodywork with a smooth junction between the radiator shroud and side panel helps rider movement and cornering. Each shroud is molded as a single piece, and Computational Fluid Dynamics guided the air-outlet vent shapes. Radiator grills optimize fin count and angle for maximum cooling performance.

The seat base uses rear-facing tongues and front-mounted tabs to simplify installation, while acceleration forces keep it secure. The new larger polyethylene fuel tank holds 2.1 gallons.

Only ten fasteners secure the major body panels—shrouds, side panels, and the seat—and all main bodywork bolts use 8 mm heads to make maintenance straightforward.

A single switch cluster handles the engine stop, ride modes, and Honda Selectable Torque Control, while the starter and HRC Launch Control sit on the right side of the Renthal Fatbar; two clamp locations and a reversible clamp give four possible handlebar positions across a 26 mm range.

Off-Road Features

The 2024 Honda CRF450RX Dirt Motorcycle includes off-road-specific details that distinguish it from the CRF450R motocrosser; softer suspension settings improve performance on rocks and roots, and a dedicated ECU map tailors power for low-traction conditions; an 18-inch rear wheel accepts a taller-sidewall tire for better compliance, the 50-tooth rear sprocket (versus the R’s 49) adjusts gearing for more torque, and a 2.1-gallon resin tank increases the distance between fuel stops; lightweight plastic hand guards protect your knuckles from brush and roost, and a forged-aluminum side stand makes trail-side parking easy.
