CRF250RX Features




































Fuel injection system
Tilting the fuel injector at a 60-degree angle sprays fuel directly towards the throttle butterfly, providing the engine with a denser and cooler fuel charge and increasing torque and power.
DOHC engine
A unique finger-follower rocker design and a double-overhead-cam (DOHC) engine layout provide more power and a higher redline.
Big bore/short stroke
With the 79mm bore and short 50.9mm stroke, it let our engineers create a high-revving engine with plenty of room for large valves—the two keys to making power in the enduro world.
Downdraft intake and exhaust
The DOHC cylinder-head design straightens the intake and exhaust tracts for improved efficiency. Straighter ports boost low-speed and midrange torque and throttle response.
Single exhaust
The bike uses a single-pipe header and a single muffler. It routes close to the center, and its light overall construction helps improve weight distribution.
Titanium intake and exhaust valves
Light is right when it comes to a high-revving engine’s reciprocating masses. We use titanium intake and exhaust valves with a super-narrow 20.5-degree included valve angle.
Large-diameter valves
The engine's twin-cam design includes large-diameter valves—33mm intakes and 26mm exhausts—which enhance flow at high rpm.
Throttle body
With a 44mm venturi designed to speed up airflow, the throttle body reaps benefits at low engine operating speeds. You get power and snap right now.
Bridged-box piston
The bridged-box piston design features a reinforcing structure between the skirts and the wrist-pin bosses that helps enable the high redline.
High-volume airbox
The airbox and air-cleaner element have a larger surface area and volume to increase midrange power. Additionally, the air filter is easy to service.
High-performance cam profiles
With input from our HRC factory team, we’ve given the bike cam profiles that help the engine produce ample bottom-end torque while retaining substantial peak power.
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.
Race-bred chassis
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.
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.
260mm front brake
The front brake disc measures 260mm, which provides excellent brake feel and weight reduction. Front and rear brake-disc guards are included.
Low battery mounting
Locating the battery low in the chassis helps lower the center of gravity, which always helps overall handling.
Low rear shock mount
With its rear shock mount low on the frame, the bike benefits from a lower center of gravity (CG) and greater handling stability.
Short swingarm
The bike's short swingarm reduces unsprung mass, improves rear-wheel traction, and lightens it for improved handling.
Showa® spring fork
Valved specifically for off-road riding, the 49mm Showa® fork features a conventional spring with a 39mm piston diameter and a 25mm rod diameter. It’s designed to provide a smooth and comfortable feel while effectively preventing bottoming out under heavy loads, such as large bumps, roots, or rocks.
Rear suspension
Our Pro-Link® design gives it 12.3 inches of suspension travel and a lightweight spring, resulting in a plush, controlled ride.
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.
Nine-plate clutch
It uses a nine-plate design to improve durability and hookup. That means less slip at peak horsepower, better torque transmission through the clutch pack, and improved durability.
Special primary and transmission ratios
It gets special primary and transmission ratios to handle the fatter midrange power and torque. The ratios let our engineers use the same shaft centerlines as the previous design so the transmission remains light and compact.
Gear-position engine mapping
An ECU with custom engine mapping for each gear delivers optimal power, setting it apart from the competition.
Large-capacity radiator
A larger radiator area results in better cooling and more power from start to finish. This design includes six percent more radiator area than the previous generation.
Engine oil scavenge pump
Deep in the engine, there’s a special oil scavenge pump that we’ve designed to be especially small and out of the way. While you may never see it, it helps keep the overall design compact.
Shared engine/gearbox lubrication
A shared engine/transmission oiling design reduces weight and makes the engine more compact, particularly for the right-side cam drive and clutch placement.
In-mold graphics
With all the time you’ll spend in the victory circle, you need to look your best. Our in-mold graphics look great and stay looking that way for a long time.
Stacked CRF logo
Like our factory racebikes, our CRF competition lineup features the vertically stacked CRF logos that look fast even sitting still.
Black rims
The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.
Handguards
Whether you’re ripping through Baja or hustling through some tight woods, handguards are absolutely necessary on a bike like this. That’s why it's equipped with them right from the factory.
Narrow seat and body
Fine-tuning the seat height and narrowing the bodywork make it easier for you to move around on the bike and help enhance rider comfort.
Sidestand
Real enduro bikes need a sidestand, and we’ve given this bike a great one. We’ve tucked it in tight, so it’s out of the way on the trail.
Electric start
It's equipped with an effortless electric starter. Convenient and lightweight, it’s a huge deal if you need to restart a stalled bike in the heat of battle.
HRC Launch Control
Push the button, hold the throttle open, and release the clutch – this bike will do the rest, launching you into the first turn with a big advantage. It's a holeshot-seeking machine!
Engine mode select button
Customize your engine's power delivery on the fly with the convenient handlebar-mounted button, allowing you to easily switch between Standard, Smooth, and Aggressive modes to suit varying track conditions or rider preferences.
