New 2022 Honda CRF250RX Competition Motorcycle

ENGINEERING NINE-PLATE CLUTCH ASSEMBLY

Say good-bye to clutch fade—the bike 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. Plus, the clutch pull is lighter, and you get improved engagement feel.

DOHC ENGINE LAYOUT

The CRF250RX uses a double-overhead-cam (DOHC) engine layout with a unique finger-follower rocker design. Together with the rest of the engine’s architecture (bore and stroke, intake tract, piston, and more), you get more power and a higher redline. New doubled intake-valve springs for 2022 are another upgrade.

BIG BORE/SHORT STROKE

The CRF250RX’s 79mm bore and short 50.9mm stroke let our engineers create a high-revving engine with plenty of room for large valves. The engine breaths and revs—the two keys to making power in the enduro world.

DOWNDRAFT INTAKE AND EXHAUST LAYOUT

The DOHC cylinder-head design let our engineers straighten out the CRF250RX’s intake and exhaust tracts. The intake is shorter and just about arrow straight, and the exhaust flows more efficiently too. The straighter ports also help boost low-speed and midrange torque as well as throttle response.

SINGLE-MUFFLER EXHAUST

Using a pressed-alloy design lets us shape the muffler for better rider ergonomics and lighter weight.

SINGLE-PIPE EXHAUST

Along with the single-muffler exhaust, 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.

WIDER WATER-PUMP DRIVE GEARS

Making the water-pump drive gear wider gives it more tooth-engagement area for longer component life.

UPGRADED CAM OILING

To help improve durability, we’ve re-routed the cam’s oil supply this year, as well as giving the CRF250RX a more rigid cam holder—better roundness and more oil means less friction and wear.

ENGINE MODE SELECT BUTTON

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 course conditions.

ENGINE OIL SCAVENGE PUMP

Deep in the engine, there’s a special oil scavenge pump. While you may never see it, it helps keep the CRF250RX’s overall design compact.

NEW PRIMARY AND TRANSMISSION RATIOS

To handle the fatter midrange power and torque, we re-engineered the CRF250RX’s primary and transmission ratios. The new ratios let our engineers use the same shaft centerlines, so the transmission itself remains light and compact.
