Honda CRF250RX: 250cc Competition

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 Exhaust

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 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 Torque

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.

New HSTC

New 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.
