CRF450RX Features

Compared to the previous generation, our engineers improved the motorcycle's auto-decompression hardware, moving it from the right side of the cam to the left. This results in less stalling at low rpms and better rideability, especially when turning.

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

The bike features a downdraft intake tract and fuel-injection body to help increase power and fuel-metering precision. This is part of the reason it offers such explosive power and massive torque.

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

By steepening the angle from 30 to 60 degrees, the injector sprays fuel directly to the throttle butterfly. The engine gets a cooler, denser fuel charge, which produces more power and better torque.

The cylinder head features a highly refined combustion-chamber shape and generous squish for increased power and torque throughout the rpm range.

A superior frame is crucial for excellent handling, and the chassis delivers. It's lightweight and responsive, with narrow main spars, and was designed with direct input from Team Honda HRC riders.

Compared to the previous generation, we revised the tripleclamps, frame, fork, and steering stem for improved chassis rigidity and responsiveness to give the bike better cornering feel.

Dunlop’s Geomax AT81 tires are specifically designed for Enduro use. They are spec'd at 21 inches for the front and 18 inches for the rear.

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

The 49mm Showa^® fork is specially tuned for off-road racing and features a conventional spring design that helps increase front-suspension precision, handling, and feel.

We’ve optimized the shape of the rear shock to match the frame design and gave it settings to work with the Enduro-tuned chassis.

Designed for enduro use, the 18-inch rear wheel and tire combo provides better bump absorption and a broader contact patch to smooth out the roots, ruts, and rocks that come with off-road riding.

The large front brake disc measures a whopping 260mm. It offers great brake feel and a pattern that reduces weight, while the caliper is designed to reduce lever fade. A front brake-disc guard is also part of the package.

The Renthal aluminum Fatbar features a bend superior to the Honda “CR” bar, making it the new standard in excellence. You will love it!

The 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.

This bike has a hydraulically actuated Nissin clutch, which is the same design as our Grand Prix MX machines and has a ten percent lighter pull. You won't need to make clutch-cable adjustments, even during long events.

The air filter and airbox shape improve torque delivery. The filter can be accessed through the left number plate, and the intake boot's filter interface has no rubber gasket, making it easier and less messy to clean and service.

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

We gave the RX a bigger, 2.1-gallon resin fuel tank. This will allow for fewer fuel stops, which can save valuable time over the course of a longer enduro.

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

Like our factory racebikes, the CRF logo is stacked and features our "in-mold" graphics, designed to remain durable after repeated track sessions and cleaning.

The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.

Our engineers used Computational Fluid Dynamics to fine-tune the radiator shrouds for increased cooling efficiency. The one-piece design ensures consistent power output and prevents overheating.

Fine-tuning the seat height and narrowing the bodywork makes it easier for you to move around on the bike and helps enhance rider comfort.

Real enduro bikes need a sidestand, and we’ve given this bike a great one. Because there’s no muffler on the left side, we have tucked the sidestand closer when it’s folded for better clearance.

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

Compared to the previous generation, 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 re-installing your seat is easier than ever.

It features a smooth seat/tank junction. The superior ergonomics make moving forward and back on the bike easier, increasing your control.

To keep the bike light, our engineers use an electric starter with a lithium-ion battery.

Customize your engine's power delivery on the fly with the convenient handlebar-mounted button, allowing you to effortlessly switch between Standard, Smooth, and Aggressive modes to suit varying track conditions or rider preference.

This special ECU program allows you to select a mode, hold the throttle open, release the clutch, and let the bike do the rest. Trust us when we say it will give you a significant advantage as you head into the first turn.
