More torqueMore torque at low revs means better drive out of corners, the shape of the pistons and connecting rods and valve timing are optimized to 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. |

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. |
Titanium fuel tankEvery gram counts on a bike in the 250 class, which is why the CRF250R has a titanium fuel tank. Light and strong, it’s also thinner than our previous plastic tank, freeing up more space and helping to centralize fuel mass. |
Flat seat/tank junctionThe CRF250R’s flat seat/tank junction makes it easier to move forward and backward on the bike, increasing your control. |
