2022 Honda CRF250R

2022 HONDA CRF250RENGINEERINGNINE-PLATE CLUTCH ASSEMBLYSay good-bye to clutch fade the bike uses a nine-plate design to improve durability and hook-up. 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.BIG BORE SHORT STROKEThe CRF250Rs 79.0mm bore and short 50.9mm stroke let our engineers create a high-revving engine with plenty of room for large valves. The engine breathes and revs the two keys to making power in the motocross world.DOHC ENGINE LAYOUTThe CRF250R uses a double-overhead-cam (DOHC) engine layout with a unique finger-follower rocker design. Together with the rest of the engines 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.DOWNDRAFT INTAKE AND EXHAUST LAYOUTThe DOHC cylinder-head design let our engineers straighten out the CRF250Rs intake and exhaust tracts. The intake is short 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 EXHAUSTUsing a pressed-alloy design lets us shape the muffler for better rider ergonomics and lighter weight.SINGLE-PIPE EXHAUSTAlong with the single-muffler exhaust, the CRF250R 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 GEARSMaking the water-pump drive gear wider gives it more tooth-engagement area for longer component life.UPGRADED CAM OILINGTo help improve durability, weve re-routed the cams oil supply this year, as well as giving the CRF250R a more rigid cam holderbetter roundness and more oil means less friction and wear.ENGINE MODE SELECT BUTTONThis 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.ENGINE OIL SCAVENGE PUMPDeep in the engine, theres a special oil scavenge pump. While you may never see it, it helps keep the CRF250Rs overall design compact.NEW PRIMARY AND TRANSMISSION RATIOSTo handle the fatter midrange power and torque, we re-engineered the CRF250Rs primary and transmission ratios. The new ratios let our engineers use the same shaft centrelines, so the transmission itself remains light and compact.NEW SHIFT DRUMBy changing from three to two lead tracks on the shift drum, weve improved the shift feel between second and third gears.GEAR-POSITION ENGINE MAPPINGTalk about smart: The CRF250R features an ECU with special engine mapping for each gear. You cant give an inch in this class, so having your engine deliver optimal power for each gear choice is one of the features that separates CRF250R riders from the rest.H SECTION CRANKLook closely at the CRF250Rs crankshaft profile and youll see its H cross-section design. Whats 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 cranks shapea big deal when you consider this part spins at over 14,000 rpm!LITHIUM-ION BATTERYLike the rest of the CRF250R, the bikes 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 LUBRICATIONThe 2022 CRF250R 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 FUEL TANKEvery gram counts on a bike in the 250 class, which is why the 2022 CRF250R has a titanium fuel tank. Light and strong, its also thinner than our previous plastic unit, freeing up more space and helping to centralize fuel mass.TITANIUM INTAKE AND EXHAUST VALVESLight is right when it comes to a high-revving engines reciprocating masses. Thats why the CRF250R 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 MANAGEMENTTotal 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? Its free horsepower you just need a bike with smart design.TECHNOLOGYHRC LAUNCH CONTROLWere talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the CRF250R will do the rest, launching you into the first turn with a big advantage. It turns your bike into a hole shot-seeking machine!ELECTRIC STARTThe CRF250R is equipped with an effortless electric starter. Convenient and lightweight, its a huge deal if you need to restart a stalled bike in the heat of battle.PERFORMANCEMORE MIDRANGE TORQUE AND POWERThe key to riding a 250 fast is to keep it in the power band. The 2022 CRF250R 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 the advantage you need.FUEL INJECTION SYSTEMBy installing the CRF250Rs fuel injector 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. Its little details like this that put the CRF250R up front.BRIDGED-BOX PISTONThe CRF250Rs bridged-box piston is the final piece to the bikes engine performance package. The design features a reinforcing structure between the skirts and the wrist-pin bosses that helps enable the CRF250Rs high redline.HIGH REDLINEWith our better-breathing DOHC design and the big-bore/short-stroke engine, the CRF250Rs rev limit is way impressive. The same goes for peak power and peak torque.HIGHER-CAPACITY RADIATORWhen youre making big power and riding long motos, you need plenty of radiator capacity to keep your engine running strong. No worriesthe 2022 CRF250R features six percent more radiator area than last years design.HIGH-PERFORMANCE CAM PROFILESWith input directly from our HRC factory team, weve given the CRF250R cam profiles that help the engine produce better bottom end torque and power, while still retaining the CRF250Rs screaming peak.HIGH-VOLUME AIRBOX AND AIR CLEANERThe 2022 CRF250R 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 years design. More air equals more power, especially in the midrange. In addition, weve made it easier to service the air filter too.MORE POWERFeel free to hold that throttle open and head for the first turn the CRF250R is designed to win that critical hole shot drag race. Youll also feel the increased low-end to mid-range torque.THROTTLE BODYWith a 44mm venturi designed to speed up airflow, the CRF250Rs throttle body really reaps benefits at low engine operating speeds. You get power and snap, right now.HANDLINGREVISED FRAME RIGIDITYGreat handling starts with a superior frame, and thats one place where the CRF250Rs chassis puts you out front. First, its lightover a pound and a half lighter than the previous generations. By making the frames 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.
