The Honda CRF250RX gives you serious motocross performance in a bike that’s specially tailored to cross country, and demanding trails. Thanks to different gearbox ratios, an 18-inch rear wheel, special engine settings, handguards, a sidestand, and a larger fuel tank, the CRF250RX is a winning formula.
Downdraft Intake and ExhaustThe combination of 79 mm bore and short 50.9 mm stroke produces a high-revving engine with plenty of room for large titanium valves. The engine breathes and revs — the keys to making power. As well, the DOHC cylinder-head design let our engineers straighten out the intake and exhaust tracts to improve power and response. The intake is shorter and just about arrow straight, and the exhaust flows more efficiently too. You’ll experience more power and better throttle response. |
Plenty of TorqueMore torque at low revs means better drive out of corners, so our engineers focused on the shape of the piston and connecting rod, while optimizing valve timing to help prioritize combustion consistency and thereby exhaust efficiency at lower revs. The bridged-box design of the piston uses a reinforcing structure between the skirt and the wrist-pin bosses that helps enable a high redline. Big torque down low, huge power up top. A winning formula. |
Durable ClutchThe CRF250RX 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 greater durability. Clutch pull remains light and engagement is easy to modulate. |
New HSTCNew on the CRF250RX for 2025, Honda Selectable Torque Control (HSTC) works to minimize rear wheel spin (thus wasted forward drive) and maximize traction. It doesn’t use a wheel-speed sensor, and, importantly, maintains feel at the throttle while managing power — ignition timing and the PGM-FI system are adjusted when the rate of change of RPM goes over a set amount. With three settings plus off to choose from, you can have your bike dialed no matter how much traction there is. |
Better BreathingTo help the CRF250RX breathe more freely, engineers redesigned the entire air-intake system. A new airbox, new filter position and new intake funnel combine to reduce restrictions to airflow. The result? Better throttle control and more consistent power delivery. |
Revised ExhaustIn combination with its less-restrictive air-intake system, the CRF250RX’s revised exhaust with straighter airflow means smoother engine operation in the mid- to high-rpm range and more-controllable acceleration. |
Single MufflerThe single muffler exhaust uses a pressed-alloy design for better rider ergonomics and lighter weight. The CRF250RX naturally uses a single-pipe header. It routes close to the center of the bike, and its light overall construction helps improve weight distribution. |
HRC Launch ControlHRC Launch Control: push the button to select the mode, hold the throttle open, release the clutch, and the bike will do the rest, launching you into the first turn with a big advantage. |
Engine Mode Select (EMS)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. |
Revised ECU SettingsOur engineers never stop searching for ways to make it easier to go faster. Revised ECU settings combine with the other chassis and powertrain improvements to make the CRF250RX an all-around better performer. |
New Aluminum FramThe CRF250RX’s aluminum frame has been radically improved for 2025 with the aim of increasing rigidity and stability. Using 70% new components, Honda engineers have managed to improve torsional and lateral rigidity in every direction, resulting in more-controlled and predictable handling — particularly in rough conditions. |
Improved Showa ForTo complement the new frame, the CRF250RX also boasts an extensively revised Showa fork. Everything from the outer tube to the axle was rethought and redesigned, resulting in improved low-speed damping, reduced friction, and enhanced rigidity. It all adds up to better control and lower lap times. |
Easier Shock AccessWhen you’re riding, you’ll appreciate the revised Pro-Link rear suspension with a new link system that’s less prone to flexing, and the redesigned shock with smoother action. When you’re wrenching, you’ll love the new ease of access to the rear suspension assembly. Removing the shock used to take about 21 minutes, by our watch, but can now be done in about nine minutes. No more removing the seat, muffler and rear frame. |
Short SwingarmThe CRF250R’s short swingarm helps make it light, and also improves rear-wheel traction and reduces unsprung mass — important considering how much power is on tap. |
Large Front BrakeThe large front-brake disc measures a whopping 260 mm, giving you strong stopping power while also being easy to modulate. |
Black RimsThey may not help you go faster, but the black D.I.D® rims sure look good. |
Electric StartConvenient and lightweight, the electric starter is a huge advantage if you need to restart the engine in the heat of battle. Like the rest of the bike, the lithium-ion battery is both super light and high performing, weighing less than half that of a conventional lead-acid battery. |
Big RadiatoAnother way the CRF250RX keeps its cool: a bigger radiator, with more fins that are angled for better airflow. |
High Capacity Fuel TankFor longer cross-country loops, the CRF250RX’s fuel tank holds a full 8 litres. |
Extra ProtectionHand guards provide extra protection against wayward stones or branches. |
Flat Seat/Tank JunctionThe CRF250RX’s flat seat/tank junction makes it easier to move forward and backward on the bike, increasing your control. |
Lightweight SidestandReal cross-country bikes need a sidestand, and we’ve given the CRF250RX a great one. Slimmer and tucked up high and out of the way, this forged alloy piece is just another example of how the CRF250RX gets it right. |
Cool RunningAnother way the CRF250RX keeps its cool: a large radiator, with fins that are angled for efficient airflow. |
