Comfort & Convenience

• ONE-PIECE RADIATOR SHROUDS: 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.
• LOWER SEAT/NARROWER BODY: 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.
• SIDESTAND: 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.
• FACTORY HANDGUARDS: Fully integrated handguards attach right to the control-lever pivots, are color-matched to your new bike, and are even vented.
• SEAT ACCESSIBILITY: 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.
• FLAT SEAT/TANK JUNCTION: It features a smooth seat/tank junction. The superior ergonomics make moving forward and back on the bike easier, increasing your control.
• ELECTRIC STARTER: To keep the bike light, our engineers use an electric starter with a lithium-ion battery.

Engineering

• HYDRAULIC CLUTCH: 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.
• AIRBOX AND FILTER: 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.
• HONDA SELECTABLE TORQUE CONTROL (HSTC): 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.
• LARGER FUEL TANK: 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.
• SKID PLATE: A factory skid plate is light and offers the kind of engine and lower-frame protection that a racer demands.

Handling

• RESPONSIVE FRAME: 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.
• TRIPLECLAMPS, AXLE, AND STEERING STEM: 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 GEOMAX AT81 TIRES: 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.
• BATTERY BOX: 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.
• SHOWA® SPRING FORK: 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.
• REAR SUSPENSION: 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.
• 18-INCH REAR WHEEL: 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.
• 260MM FRONT BRAKE: 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.
• RENTHAL FATBAR: The Renthal aluminum Fatbar features a bend superior to the Honda “CR” bar, making it the new standard in excellence. You will love it!
• SWINGARM: 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.

Performance

• 450CC UNICAM® ENGINE: Honda's Unicam® cylinder heads combine single- and double-overhead-cam designs to create a compact engine with a narrow valve angle. This allows for a higher compression ratio and lower center of gravity.
• DECOMPRESSION SYSTEM: 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.
• 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 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.
• TITANIUM INTAKE VALVES: Lightweight titanium intake valves cut down on reciprocating mass and permit the use of smaller valve springs, reducing overall engine height and weight.
• FUEL INJECTION BODY POSITION: 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.
• 13.5:1 COMPRESSION RATIO: The cylinder head features a highly refined combustion-chamber shape and generous squish for increased power and torque throughout the rpm range.

Style

• RACE STYLING: 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.
• BLACK DID RIMS: The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.

Technology

• ENGINE MODE SELECTION BUTTON: 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.
• HRC LAUNCH CONTROL: 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.
