Honda CRF450RX Overview

The Honda CRF450RX is a race-bred bike well-suited for closed-course off-road competition. However, it also makes a great trail bike for riders looking for a capable and versatile machine.

The Honda CRF450RX model features a number of modifications that make it more suitable for trail riding, including softer suspension, a larger fuel tank, and an 18-inch rear wheel. These changes give the Honda CRF450RX a more comfortable ride and make it easier to handle in technical terrain.

Of course, the Honda CRF450RX is still a race bike at heart. It has a powerful engine and agile handling, making it a blast to ride on fast trails. However, it is also more forgiving than the CRF450R, making it a better choice for riders who are not expert motocross racers.

If you are looking for a capable and versatile trail bike that can hold its own on the track, the Honda CRF450RX is a great option.

2024 Honda CRF450RX Features

LIGHT, NARROWER FRAME

Great handling starts with a superior frame. The Honda CRF450RX’s chassis was designed to be narrow, lightweight, and more responsive, thanks to reduced lateral rigidity. The result is a bike that gets into, around, and out of corners faster.

ROBUST SUSPENSION MOUNTING POINTS

More robust suspension mounting points enhance the chassis and suspension stability. When the suspension works better, the chassis works better, and you get better drive and handling everywhere.

NARROWER SWINGARM

We’ve matched the swingarm’s lateral rigidity to the rest of the chassis, designed in conjunction with the frame by using narrower main members (just like the frame uses narrower main spars). You get a balanced, fully integrated approach to frame stiffness, letting you get around corners faster and with a better feel.

BATTERY BOX

The battery box is positioned low for an improved center of gravity. It’s also easy to service and water-tight, so there’s less to worry about when racing in wet conditions.

FRONT SUSPENSION

Increased front suspension stroke offers better handling and rider comfort. The axle-holding fixtures are positioned at the bottom of each fork leg to help increase rigidity and enhance steering precision and suspension performance.

TRIPLE CLAMPS

The Honda CRF450RX is a perfectly matched package. With the frame and swingarm featuring a retuned lateral stiffness, and the fork legs featuring a stiffer axle fixture, we joined the two with upper and lower triple clamps. Working in concert, they help improve and balance total rigidity, responsiveness and turning performance.

REAR SUSPENSION

We’ve optimized the shape of the rear shock to match the frame and gave it settings to work with the chassis. The shock valve resets faster for better response. And, of course, the RX gets its shock settings optimized for Enduro riding.

SHOWA® SPRING FORK

The 49mm Showa® fork is specially tuned just for the Honda CRF450RX and features a conventional spring design that helps increase the CRF450RX’s front-suspension precision, handling and feel.

SWINGARM

The Honda CRF450RX’s swingarm uses a special fabrication technique that lets us fine-tune the flex to work with the chassis and give you better rear traction and cornering precision.

EXHAUST PIPE

The single-muffler exhaust is positioned closer to the center of the bike to help improve weight distribution.

SINGLE-MUFFLER EXHAUST

The Honda CRF450RX muffler gets a strong outer shell and revised inner pipe construction. Changing the muffler’s construction to a pressed-alloy design lets us reshape it for better rider ergonomics and lighter weight.

HYDRAULIC CLUTCH

The Honda CRF450RX includes a hydraulically actuated clutch. Made by Nissin, it’s the same design as in our Grand Prix MX machines and performs better than third-party conversions. You get a clutch-lever pull that’s ten percent lighter at its peak, even though it’s paired with a stronger clutch. Plus, you’ll never have to worry about making a clutch-cable adjustment, even during the longest events.

Honda SELECTABLE TORQUE CONTROL (HSTC)

Changing terrain requires changing power character. No worries: The Honda CRF450RX features our Honda Selectable Torque Control (HSTC). Depending on how much traction is available, you can choose from one of three settings to dial your bike in perfectly.

260mm FRONT BRAKE

The Honda CRF450RX’s large front-brake disc measures a whopping 260mm. You get a great brake feel and a pattern that reduces weight. Front and rear brake disc guards are part of the package too.

ENGINE MODE SELECT BUTTON

This simple handlebar-mounted button lets you dial in the engine power delivery character with a thumb push. Choose Standard, Smooth and Aggressive, depending on track conditions or rider preference.

RESIN FUEL TANK

The 2.1-gallon capacity will let many riders complete a three-hour Enduro with just one fuel stop.

COMPACT FUEL PUMP

No detail is too small for our engineers—especially if they can make it smaller and lighter. That’s why they reduced the number of attaching fasteners from six to four.

RADIATOR SHROUDS

Using computer-aided Computational Fluid Dynamics, we’ve fine-tuned the Honda CRF450RX’s radiator shrouds to increase cooling. They’re now a one-piece design, but more important, better cooling equals more consistent power and longer into a race, especially when you’re really on the gas and working the engine hard.

HRC LAUNCH CONTROL

We’re talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the Honda CRF450RX will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!

LIGHT OVERALL WEIGHT

On an enduro racer, less weight is always better. That’s why our engineers are such fanatics when trimming grams from the CRF450RX. You’ll feel the benefits everywhere: in acceleration, suspension action, and most of all.

REAR BRAKE PADS

Brakes are for more than just stopping: they help you set up the bike in turns and jumps, which is why we pay so much attention to detail, like brake pads. They’re designed to last longer and give you even more stopping power—a real win/win to help you win.

AIRBOX AND FILTER

The air filter and airbox shape are designed to help deliver more torque. You can access the airbox through the left number plate. And because the filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy.

ELECTRIC START

Kickstarting? Maybe if you’re riding in the vintage class, but not here. Our engineers can make the Honda CRF450RX lighter by ditching the Kickstarter entirely. Electric starters and lithium-ion batteries are so light now and so good that putting them on a bike like this is a win/win combination. And winning is what a CRF450RX is all about.

SWITCH ASSEMBLY

Controls used to be your bike’s shifter, clutch, and brakes. Now you have launch assist, selectable power modes, and more.

DUNLOP GEOMAX AT81 TIRES

The Honda CRF450RX’s Dunlop Geomax tires are specially designed for Enduro use. The AT81 tires are spaced at 21 inches for the front and 18 inches for the rear. You read that right: the CRF450RX rolls on an 18-inch rear wheel.

450cc UNICAM® ENGINE

Honda’s Unicam® cylinder heads combine single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is occupied in the cylinder head, the camshaft sits lower for a more compact engine and a lower center of gravity.

MID-RANGE TUNED INTAKE TRACT, THROTTLE BODY, AND CAM TIMING

To help boost the Honda CRF450RX’s low-and midrange power delivery, we changed the intake tract and throttle body to boost intake-mixture speed. ECU settings, ignition maps, and cam timing using less overlap are all inspired by our factory HRC racebikes, and all work together to help you get on the gas sooner and roost out of corners faster and harder.

DECOMPRESSION SYSTEM

You can’t see this unless you take the engine apart, but you’ll notice it on the track. You’ll experience less stalling at extremely low RPM (think deep into a turn without downshifting) and better rideability.

CYLINDER HEAD

Together with the single-muffler exhaust, the oval-shaped centralized exhaust port boosts power from 5000 rpm up and increases exhaust efficiency.

DOWNDRAFT FUEL INJECTION

The Honda CRF450RX features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It’s part of the reason the Honda CRF450RX offers such explosive power and massive torque, especially out of the starting line and in the critical first 100 feet of the race to the first turn.

TITANIUM INTAKE VALVES

Lightweight titanium intake valves cut down on reciprocating mass and permit the use of smaller valve springs, reducing overall engine height.

FUEL INJECTOR BODY POSITION

By steepening the angle from 30 to 60 degrees, the injector sprays fuel back to the throttle butterfly. The engine gets a cooler, denser fuel charge for more power and better torque. It’s little details like this that put the CRF450RX up front.

DOUBLE-SPRAY INJECTOR SETTINGS

The CRF450RX’s fuel-injection system sprays twice per intake cycle. That helps increase fuel atomization without adding the weight or complexity of a second injector. The better fuel atomization means more power in the midrange and on overrev—you’ll feel it the first time you race.

13.5:1 COMPRESSION RATIO

Honda engineering at its best: The CRF450RX’s cylinder head features a highly refined combustion-chamber shape and generous squish area, allowing an impressive 13.5:1 compression ratio for superior efficiency and power.

CYLINDER HEAD LAYOUT

The CRF450RX uses our latest finger-follower rocker design. The Unicam cylinder head remains one of the most efficient in the off-road world, giving you the design and performance of a double-overhead-cam layout but the compactness of a single-overhead-cam design.

SKID PLATE

A factory skid plate is light and offers the engine and lower-frame protection that a racer demands.

SLIM BODYWORK

Narrow bodywork makes moving around on your bike a lot easier and maximizes your riding freedom.

FACTORY HANDGUARDS

Fully integrated handguards attach right to the control-lever pivots, are color-matched to your new bike, and are even vented.

RENTHAL “FATBAR”

The aluminum Renthal Fatbar features a bend even better than the legendary Honda “CR” bar. It’s the new standard of excellence—you’ll love it!

SEAT ACCESSIBILITY

Sometimes you need to think out of the box—that’s what we did with the CRF450RX’s seat. We moved the attaching bolts from the rear to the front and the tongue from the front to the rear. The result: When it’s time for service, removing and installing your CRF450RX seat is easier than ever.

SIDE STAND

Real Enduro bikes need a side stand, and we’ve given the CRF450RX a great one. Since there’s no muffler on the left side, we could tuck the side stand closer when it’s folded for better clearance.

CABLE ROUTING

You may not notice it at first, but re-routing the CRF450RX’s throttle cables and hydraulic clutch line let our engineers shave almost half a pound off the bike. Light is always right!
