More torqueMore torque at low revs means better drive out of corners, so our engineers changed the shape of the piston and connecting rod and optimized valve timing to help improve 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. |
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. |
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. |
Short swingarmThe short swingarm helps make it light, and also gives the bike better rear-wheel traction — important considering how much power is on tap. The swingarm’s design focuses on improved stability and handling, while still reducing the bike’s unsprung mass. |
Dunlop® Geomax tiresThe CRF250RX’s Dunlop® Geomax tires are specially designed for cross-country use. The AT81 tires are spec’d at 90/90-21 for the front and 110/100-18 for the rear. You read that right: the CRF250RX rolls on an 18-inch rear wheel. |
260 mm front brakeThe large front-brake disc measures a whopping 260 mm, giving you superior 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. |
Bigger radiatorAnother way the CRF250RX keeps its cool: a bigger radiator, with more fins that are angled for better airflow. |
Narrower fuel tankFor longer cross-country loops, the CRF250RX’s resin fuel tank holds a full 8 litres. It’s narrower, too, improving rider manoeuvrability. |
Hand protectionKnuckle 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. |
