More 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.

The CRF250RX’s clutch is all about staying durable - accomplished with nine clutch plates and a generous spring count in the damper chamber, along with a rigid clutch centre, and plenty of lubrication. All of these factors combine to enhance clutch strength and performance.

The CRF250RX features an air-cleaner element with plenty of surface area and volume. More air equals more power, especially in the midrange. In addition, we’ve made it easier to service the air filter too.

The 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.

The 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 means an intake and exhaust tract that are straight enough to enable strong power and response. The intake is short and just about arrow-straight, and the exhaust flows efficiently too. You’ll experience plenty of power and throttle response.

HRC 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.

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.
