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.
Features may include:
Engine & DrivetrainThe 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.
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 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.
Chassis & SuspensionThe 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.
To 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.
When 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.
