2024 Honda CRF450RX Totalmotorcycle.com Features and Benefits
ENGINE / DRIVETRAIN
The CRF450RX engine boasts exceptional bottom-end and midrange power and torque, making for a linear delivery that is strong but manageable, even as the rider tires, while peak power is also very good. A five-hole piston oil jet and dual 12mm drum scavenge pump manage lubrication.
Cylinder Head: The design of the Unicam® cylinder head, with the decompressor system’s counterweight on the left end of the camshaft, contributes to combustion stability in the extremely low rpm range and for strong-but-manageable power delivery on corner exits, for example, as well as resistance to stalling. Engineers followed the direction of Team Honda HRC by optimizing the cam profile for low-end torque. As before, the cylinder head cover is magnesium, with a thin-wall design for weight savings.
Intake: The CRF450RX features a downdraft intake design that delivers strong, efficient power, and a large air boot (4.1 liters on the clean side of the air filter) achieves strong torque at low rpm. Following feedback from HRC, the 44mm throttle body ensures smooth power delivery at low speed. In addition, the narrow intake port shape and long air funnel result in strong low-end torque and crisp throttle response. The airbox is accessed with the removal of a single side panel bolt. The 60º fuel-injector angle enables the spray to reach all the way to the back of the butterfly, thus cooling the upstream side of the intake path for maximum intake efficiency and torque feel.
Exhaust: The engine’s exhaust port is centrally located, has an oval shape and is very straight, optimizing exhaust efficiency and torque characteristics. With the engine’s central exhaust-port location, the exhaust header and muffler are positioned close to the vehicle’s centerline for a slim profile, contributing to freedom of movement for the rider. The muffler is constructed with strong A6061-T6 aluminum for impact resistance and weight savings. A dual resonator design optimizes power, while simultaneously minimizing noise.
Clutch: The clutch is hydraulically actuated and has eight plates and a large volume for good durability with minimal slippage and light lever pull.
Electronics: A gear-position sensor allows the use of three specific ignition maps for first and second, third and fourth, and fifth gears. There are options for Standard, Smooth and Aggressive ignition maps, selectable via an all-new handlebar-mounted switch, enabling simple tuning depending on rider preference or course conditions.
In addition, Honda Selectable Torque Control offers three levels of intervention. HSTC monitors rpm spikes and responds by temporarily reducing torque by retarding ignition timing and controlling PGM-FI to aid rear traction. The three different modes differ in drive-management level, for differing riding conditions or rider preferences:
- Mode 1: The system intervenes most lightly and waits the longest to do so—useful for reducing wheel-spin and maintaining control in tight corners.
- Mode 2: A midpoint between modes 1 and 3 in terms of how quickly and assertively the system intervenes.
- Mode 3: The system intervenes most quickly and assertively, which helps in conditions that are slippery or muddy.
The CRF450RX’s handlebar-mounted switch allows selection between three modes, depending on conditions and rider preference. The HSTC system can also be switched off completely.
HRC Launch Control provides the best option for a strong start and also has three modes to choose from:
- Level 1: 9,500 rpm, for high-traction conditions and/or advanced riders
- Level 2: 8,500 rpm, for high-traction conditions and/or average riders
- Level 3: 8,250 rpm, for slippery conditions and/or novice riders
The Engine Mode Select Button (EMSB) alters the engine’s characteristics and three maps are available to suit riding conditions or rider preference:
- Mode 1: Standard
- Mode 2: Smooth
- Mode 3: Aggressive
CHASSIS / SUSPENSION
The motorcycle’s heavier components are positioned centrally and as low as possible for precise cornering without sacrificing high-speed tracking, and to achieve minimal squat under acceleration and negligible pitching during hard braking.
Frame / Swingarm / Subframe: The frame uses narrow main spars and features optimized reinforcement ribbing on the backside of the pivot plate, contributing to the low frame weight of just 18.5 pounds. Frame rigidity is optimized, allowing the front and rear suspension components to move freely and avoid binding, improving stability and bump absorption.
The subframe features a simple design that weighs just 2.0 pounds. The swingarm is narrow, providing good clearance in ruts, with rigidity tuned to maximize rear traction and cornering.
Suspension: The Pro-Link® rear-suspension system uses a Showa shock absorber with adjusters on the right side and an ultra-light steel shock spring. Because of the optimized frame rigidity, the shock moves freely, minimizing harshness, while offering hold-up for big impacts and performance in ruts.
Front suspension comprises a 49mm inverted Showa® coil-spring fork and a gas-liquid separation structure. The fork setting is paired with that of the shock, for proper front-rear balance. The upper and lower triple clamps are designed to offer a good rigidity balance for optimum handling and feel through corners.
Wheels: Black D.I.D rims deliver durable performance and good looks. Petal-style brake rotors disperse heat, and a low-expansion front brake hose gives strong feel and consistent stopping power. The CRF450RX comes with Dunlop’s rugged AT81 tires, designed for all around performance across a variety of off-road terrain.
DESIGN
The CRF450RX has slim bodywork, with a smooth junction of the radiator shroud and side panel, facilitating rider movement and cornering. Each radiator shroud is produced in a single piece instead of two separate parts, and Computational Fluid Dynamics (CFD) were used to design air-outlet vents in the shrouds. The radiator grills optimize the number of fins and their angle, maximizing cooling performance.
The seat base has rearward-facing tongues and front-located mounting tabs, easing installation, and using acceleration forces to keep the seat securely in place. The larger polyethylene fuel tank holds 2.1 gallons
Only 10 fasteners are used to secure all of the main bodywork components—both radiator shrouds, both side panels and the seat, and all of the bolts for the main bodywork parts have 8mm heads, simplifying maintenance.
A single switch cluster addresses several functions: engine stop, ride-modes and Honda Selectable Torque Control (HSTC). The starter and HRC launch control are on the right side of the Renthal® Fatbar® handlebar. There are two locations for the handlebar clamp, and the clamp can be turned 180º; as a result, four different mounting positions are possible, through a range of 26mm.
Off-Road Features: The CRF450RX comes with a number of off-road-focused features that set it apart from its motocross-focused CRF450R sibling.
Softer suspension settings enhance performance over rocks and roots while the dedicated ECU map optimizes power delivery for low-traction off-road conditions. The 18-inch rear wheel allows for a taller tire sidewall, improving compliance over rough terrain and the 50-tooth rear sprocket (compared to the R’s 49) adapts the gearing for increased torque. A 2.1 gallon resin tank increases range between fuel stops.
Lightweight plastic handguards provide knuckle coverage from brush and roost and can be easily removed. The CRF450RX is also equipped with a forged-aluminum side stand for convenient on-trail parking.
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.
NEW ENGINE HANGERS
For 2023, we’ve made the cylinder-head engine hangers stronger and stiffer, and made the frame thicker where the hangers attach. The whole assembly is more rigid now, to enhance handling.
NEW SUSPENSION MOUNTING POINTS
More robust suspension mounting points this year 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
New this year, we made the CRF450RX muffler stronger, by using a new outer shell. We also changed the inner pipe construction. Even with these improvements, it still weighs the same. Changing the muffler’s construction to a pressed-alloy design last year let us reshape it too, for better rider ergonomics and lighter weight.
ENGINEERING
HYDRAULIC CLUTCH
The CRF450RX includes the first hydraulically actuated clutch we’ve offered outside of our works bikes. 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 last year.
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 than ever.
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.
SWITCH ASSEMBLY
Controls used to be your bike’s shifter, clutch, and brakes. Now you have things like launch assist, selectable power modes, and more.
PERFORMANCE
DUNLOP GEOMAX AT81 TIRES
The CRF450RX’s Dunlop Geomax tires are specially designed for Enduro use. You read that right: the CRF450RX rolls on an 18-inch rear wheel.
NEW INTAKE TRACT, THROTTLE BODY, AND CAM TIMING
To help boost the CRF450RX’s low-and midrange power delivery, for 2023 we’ve made changes to the intake tract and throttle body to boost intake-mixture speed. New 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.
450cc UNICAM® ENGINE
Honda’s Unicam® cylinder heads combine the best of single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also 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 taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity.
DECOMPRESSION SYSTEM
You can’t see this unless you take the engine apart, but you’ll notice it on the track. Our engineers redesigned the auto decompression hardware last year, and also moved it from the right side of the cam to the left. The result is less stalling at extreme low RPM (think deep into a turn without downshifting) as well as 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 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 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 now sprays fuel all the way 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.
COMFORT
SLIM BODYWORK
Narrow bodywork makes it a lot easier to move around on your bike, 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 that’s even better than the legendary Honda “CR” bar. It’s the new standard of excellence—you’re gonna 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 new CRF450RX’s seat is easier than ever.
FLAT SEAT/TANK JUNCTION
The CRF450RX features a flat seat/tank junction, including a titanium fuel tank. The superior ergonomics make it easier to move forward and back on the bike, increasing your control.
BLACK DID RIMS
They may not help you go faster, but the black DID DirtStar rims sure look good.
SIDESTAND
Real enduro bikes need a sidestand, and we’ve given the CRF450RX a great one. Since there’s no muffler on the left side, we could tuck the sidestand in 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!
