Comfort

• KNUCKLE GUARDS: Whether you’re ripping through Baja or hustling your way through some tight woods, on a bike like the CRF250RX, handguards are a real necessity. That’s why our 2022 bike is now equipped with them right from the factory.
• BLACK RIMS: They may not help you go faster, but the sweet black DID rims sure look good.
• LOWER SEAT / NARROWER BODY: We’ve lowered the seat by 10mm on the 2022 CRF250RX, and narrowed the radiator shrouds by 17mm as well. Combined, they make it easier for you to move around on the bike and help it slip through tight trails even easier. Plus, the changes enhance rider comfort.
• BODYWORK MOUNTING: It may seem like a small thing, but every second counts when you’re servicing your bike between rides. That’s why for 2022 we’ve reduced the number of bodywork fasteners. Fewer bolts mean enhanced serviceability, at the track or in your garage.
• FLAT SEAT / TANK JUNCTION: The 2022 CRF250RX features a flat seat/tank junction. The superior ergonomics make it easier to move forward and back on the bike, increasing your control.
• "IN MOLD" GRAPHICS: With the all the time you’ll be spending in victory circle, you need to look your best. The CRF250RX has you covered. Our “in mold” graphics look great, and stay looking good longer.
• REAR SUBFRAME: The CRF250RX’s subframe uses extruded rear members that produce a 20-percent reduction in weight versus the previous generation CRF250R. Since that weight comes off the top of the bike, it also contributes to the CRF250RX’s low center of gravity.
• SIDESTAND: Real enduro bikes need a sidestand, and we’ve given the CRF250RX a great one. Tucked up high and out of the way, this lightweight forged alloy piece is just another example of how the CRF250RX gets it right. For 2022 we’ve tucked it in even tighter so it’s out of the way on the trail.
• SMOOTH STYLING: Blending the CRF250RX’s body panels does more than just make the bike look smooth, fast, and stylish. It also helps you move around on the bike while riding. Nothing wrong with smooth, fast, and stylish, though.

Convenience

• HRC LAUNCH CONTROL: We’re talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the CRF250RX will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!
• ELECTRIC START: The CRF250RX is equipped with an effortless electric starter. Convenient and lightweight, it’s a huge deal if you need to restart a stalled bike in the heat of battle.

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.
• 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.
• SHIFT DRUM: By changing from three to two lead tracks on the shift drum, we’ve improved the shift feel between second and third gears.
• GEAR-POSITION ENGINE MAPPING: Talk about smart: The CRF250RX features an ECU with special engine mapping for each gear. You can’t give an inch in this class, so having your engine deliver optimal power for each gear choice is one of the features that separates CRF250RX riders from the rest.
• "H" SECTION CRANK: Look closely at the CRF250RX’s crankshaft profile and you’ll see its “H” cross-section design. What’s up with that? Just like a structural “I” beam in an aircraft wing or a skyscraper, it boosts strength and cuts weight over a conventional crank’s shape—a big deal when you consider this part spins at over 14,000 rpm!
• HIGH CAPACITY RESIN FUEL TANK: For longer enduro loops, the CRF250RX features a large resin fuel tank that holds over two gallons.
• LITHIUM-ION BATTERY: Like the rest of the CRF250RX, the bike’s Lithium-Ion battery is both super light and high performing. In fact, it weighs less than half the weight of a conventional lead-acid battery.
• SHARED ENGINE / GEARBOX LUBRICATION: The 2022 CRF250RX uses a shared engine/transmission oiling design. Why? Combining the two systems shaves weight and helps make the engine more compact, especially when it comes to placing the right-side cam drive and the clutch so close together.
• TITANIUM INTAKE AND EXHAUST VALVES: Light is right when it comes to a high-revving engine’s reciprocating masses. That’s why the CRF250RX uses titanium intake and exhaust valves. Plus, the valve angle is a super-narrow 20.5 degrees (included). Ovalized valve springs and long-wearing Diamond-Like Carbon (DLC) treated finger rockers complete the package.
• TOTAL AIR MANAGEMENT: Total air management means complete attention to how efficiently air gets through the intake, through the head, and out the exhaust. Eliminate losses here, and you make more power everywhere. And the best part? It’s free horsepower—you just need a bike with smart design.

Handling

• DUNLOP GEOMAX TIRES: The CRF250RX’s Dunlop Geomax tires are specially designed for enduro use. The AT81 tires are spec’d at 80/100-21 for the front and 110/100-18 for the rear. You read that right: the CRF250RX rolls on an 18-inch rear wheel.
• REVISED FRAME RIGIDITY: Great handling starts with a superior frame, and that’s one place where the CRF250RX’s chassis puts you out front. First, it’s light—over a pound and a half lighter than the previous generation’s. By making the frame’s main spars narrow, we save weight, but more important we make the chassis more responsive by fine-tuning the lateral rigidity. The result is a bike that gets into, around, and out of corners faster.
• 260mm FRONT BRAKE: The CRF250RX’s large front-brake disc measures a whopping 260mm. You get great brake feel and a pattern that cuts down on weight. Front and rear brake-disc guards are part of the package too.
• LOW BATTERY MOUNTING: Locating the battery low in the chassis helps to lower the CRF250RX’s center of gravity—and that always helps overall handling.
• LOW REAR SHOCK MOUNT: With its low rear shock mount on the frame, the CRF250RX benefits from both a lower center of gravity (cg) as well as chassis stability.
• SHORT SWINGARM: The CRF250RX’s short swingarm helps make it light, and also helps give the bike better rear-wheel traction, and reduces unsprung mass, important considering how much power you have on tap.
• SHOWA® SPRING FORK: The 49mm Showa® fork features a conventional spring design that helps increase the CRF250RX’s front-suspension precision, handling and feel. The 39mm piston diameter and 25mm rod diameter guarantee a plush feel and supple action. New suspension settings for 2022 that are exclusive to the RX keep you dialed in.
• TUNED TRIPLE CLAMPS: The CRF250RX is a perfectly matched package. Which is why for 2022 we’ve optimized the triple clamps’ rigidity. You’ll notice the difference in performance, especially in ruts.
• REAR SUSPENSION: We’ve given the 2022 CRF250RX five millimeters more suspension stroke, along with a lightweight spring. Combine that with a new Pro-Link ratio, and you get a 110-gram weight savings along with a more plush ride.
• SINGLE EXHAUST ROUTING: The 2022 CRF250RX’s single-pipe exhaust is going to get a lot of attention, but another advantage that you might not think of is how it lets you move more freely on the bike. By tucking in unobtrusively, it makes moving around on the bike easier than ever.
• TWIN SPAR ALUMINUM FRAME: The CRF250RX’s latest twin-spar aluminum frame is virtually identical to the CRF450R motocrosser’s except for the lower engine cradle where the engine mounts. It’s the foundation for the 250’s superb handling.

Performance

• MORE MIDRANGE TORQUE AND POWER: The key to getting the most out of a 250 is to keep it in the powerband. The 2022 CRF250RX features a new cam, new valve timing, and a new press-fit cam sprocket along with new ignition timing. Together they boost the critical midrange torque and power significantly, giving you a broad powerband and the advantage you need.
• FUEL INJECTION SYSTEM: By tipping the CRF250RX’s fuel injector back at a 60-degree angle, the injector sprays fuel all the way back to the throttle butterfly. The engine gets a cooler, denser fuel charge for more power and better torque. It’s little details like this that put the CRF250RX up front.
• HOLESHOT-WINNING POWER: Feel free to hold that throttle open and head for the first turn—the CRF250RX is designed to win that critical holeshot drag race. You’ll also feel the increased low-end to mid-range torque.
• BRIDGED-BOX PISTON: The CRF250RX’s bridged-box piston is final piece to the bike’s engine performance package. The design features a reinforcing structure between the skirts and the wrist-pin bosses that helps enable the CRF250RX’s high redline.
• HIGH REDLINE: With our better-breathing DOHC design and the big-bore/short-stroke engine, the CRF250RX’s rev limit is way impressive. The same goes for peak power and peak torque.
• HIGH-VOLUME AIRBOX AND AIR CLEANER: The 2022 CRF250RX features an air-cleaner element with plenty of surface area and volume. Plus, the airbox itself has a whopping 78 percent more capacity than last year's model. More air equals more power, especially in the midrange. In addition, we’ve made it easier to service the air filter too.
• LARGE-CAPACITY RADIATOR: A bigger radiator means better cooling, and better cooling means more power, from the start of your ride to the finish. With that in mind, the 2022 CRF250RX features six percent more radiator area than last year’s bike.
• LARGE VALVE DIAMETERS: The CRF250RX’s valves don’t just have impressive lift, the valves themselves are large-diameter too—33mm intakes and 26mm exhausts. Combined with the high lift, the twin-cam CRF250RX flows a lot more, especially at high revs when you’re wicking it up.
• HIGH-PERFORMANCE CAM PROFILES: With input directly from our HRC factory team, we’ve given the CRF250RX new cam timing in 2022 to help the engine produce better bottom end torque and power while still retaining the CRF250RX’s substantial peak.
• THROTTLE BODY: With a 44mm venturi designed to speed up airflow, the CRF250RX’s throttle body really reaps benefits at low engine operating speeds. You get power and snap, right now.
