CRF450RX
UNLEASH YOUR OFF-ROAD DREAMS
Imagine the ultimate dream bike for dirt riders—a machine that combines the power, agility, and precise handling of a factory motocrosser with the finesse needed to conquer off-road adventures. That’s the 2024 Honda CRF450RX. We've taken all the remarkable enhancements from our 2024 CRF450R motocrosser and infused it with some engineering magic, resulting in the perfect off-road companion. You’ll experience increased low- and midrange torque through revised ECU and fuel injection settings, along with the enhanced usability provided by a wide-ratio five-speed transmission. But that's not all: The RX showcases our extraordinary Honda Selectable Torque Control, empowering you to optimize traction in any scenario. Additionally, a lightweight chassis, 18-inch rear wheel, and specialized suspension settings are meticulously designed to conquer every terrain you encounter. And here's the icing on the cake: our unrivaled reputation for quality and reliability. The CRF450RX is the genuine article, as any off-road rider will attest!
HANDLING
LIGHT, NARROWER FRAME
Great handling starts with a superior frame. The 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 chassis and suspension stability. When the suspension works better, the chassis works better, and you get better drive and handling everywhere.
NARROWER SWINGARM
Designed in conjunction with the frame, by using narrower main members (just like the frame uses narrower main spars), we’ve matched the swingarm’s lateral rigidity to the rest of the chassis. What you get is a balanced, fully integrated approach to frame stiffness, letting you get around corners faster and with better feel.
BATTERY BOX
The battery box is positioned low, for an improved center of gravity. It’s also easy to service, as well as 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 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 shocks valving resets faster for better response. And, of course, the RX gets its own shock settings optimized for Enduro riding.
SHOWA® SPRING FORK
The 49mm Showa® fork is specially tuned just for the CRF450RX, and features a conventional spring design that helps increase the CRF450RX’s front-suspension precision, handling and feel.
SWINGARM
The 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 CRF450RX muffler gets a strong outer shell and revised inner pipe construction. Changing the muffler’s construction to a pressed-alloy design let us reshape it too, for better rider ergonomics and lighter weight.
ENGINEERING
HYDRAULIC CLUTCH
The 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 CRF450RX features our Honda Selectable Torque Control (HSTC). You can choose from one of three settings to perfectly dial your bike in depending on how much traction is available.
260mm FRONT BRAKE
The CRF450RX’s large front-brake disc measures a whopping 260mm. You get great brake feel and a pattern that cuts down on 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 engine power delivery character with a push of your thumb. Choose between 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 CRF450RX’s radiator shrouds to increase cooling. They’re now a one-piece design, but more important, better cooling equals more consistent power, 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 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 it comes to trimming grams from the CRF450RX. You’ll feel the benefits everywhere: in acceleration, in suspension action, and most of all at the end of the day.
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.
CONVENIENCE
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. By ditching the kickstarter entirely, our engineers can make the CRF450RX lighter. 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.
