CRF250R

ENGINEERING

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 CRF250R will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!

BIG BORE/SHORT STROKE

The CRF250R’s 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.

CLUTCH DESIGN AND MATERIALS

The CRF250R’s clutch uses two different types of friction material. Why? The clutch can handle the increased power of the engine without being any larger. The lighter rotating weight is directly related to how fast the engine revs. Stronger clutch springs for 2020 help cope with all that power.

DOHC ENGINE LAYOUT

The CRF250R 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.

DOWNDRAFT INTAKE AND EXHAUST LAYOUT

The DOHC cylinder-head design let our engineers straighten out the CRF250R’s intake and exhaust tracts. The intake is short and just about arrow straight, and the exhaust flows more efficiently too. No athlete’s going to win a sprint if they try to run while holding their breath, and it’s no different with your bike’s engine. You’ll experience both more power and better throttle response.

REFINED DUAL-EXHAUST SYSTEM

The CRF250R’s dual-exhaust system is light, compact, and positioned close and low in the frame to take weight off the rear end and bring more mass to the bike’s center for improved handling. Fine-tuning the pipes’ length for 2020 helps give you more low- and midrange torque.

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 track 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 CRF250R’s overall design compact.

GEAR-POSITION ENGINE MAPPING

Talk about smart: The CRF250R 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 CRF250R riders from the rest.

GRADUAL PIPE-BEND RADIUS

Notice how the CRF250R’s dual exhaust pipes make gradual, large-radius bends out of the head, then flow straight back to the mufflers with no abrupt angle changes. Getting the exhaust out of the engine—while still maintaining a tuned exhaust length, is the key to power, while the pipes’ low mass and twin-silencer design optimize the CRF250R’s center of mass for superior handling.

"H" SECTION CRANK

Look closely at the CRF250R’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!

LITHIUM-ION BATTERY

Like the rest of the CRF250R, 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 2020 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 TANK

Every gram counts on a bike in the 250 class, which is why the 2020 CRF250R has a titanium fuel tank. Light and strong, it’s also thinner than our previous plastic unit, freeing up more space and helping to centralize fuel mass.

TITANIUM INTAKE AND EXHAUST VALVES

Light is right when it comes to a high-revving engine’s reciprocating masses. That’s 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 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.

CONVENIENCE

ELECTRIC START

The CRF250R 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.

PERFORMANCE

DOUBLE-SPRAY INJECTOR SETTINGS

The CRF250R’s fuel-injection system sprays twice per intake cycle. That helps increase fuel atomization without adding the weight or complexity of a second injector. The better fuel atomization means more power in the midrange and on over rev—you’ll feel it the first time you race.

BIGGER RADIATOR

We’ve increased the radiator size this year for better cooling—and since the new bike makes more power, it needs more cooling!

HIGH REDLINE

With our better-breathing DOHC design and the big-bore/short-stroke engine, the CRF250R’s rev limit is way impressive. The same goes for peak power and peak torque.

MORE POWER

With the power updates for 2020, feel free to hold that throttle open and head for the first turn—the CRF250R is designed to win that critical holeshot drag race. You’ll also feel the increased low-end to mid-range torque.

NEW 2020 CAM PROFILES

With input directly from our HRC factory team, we’ve changed the intake cam profiles on our 2020 model to work with the new valves. You should feel better bottom end torque and power, while still retaining the CRF250R’s screaming peak.

NEW 2020 PISTON

Coordinated to work with the new cam profile and combustion-chamber shape, it’s the final piece to the CRF250R’s engine performance package. The bridged-box design features a reinforcing structure between the skirts and the wrist-pin bosses that helps enable the CRF250R’s high redline.

NEW, HIGH-VOLUME AIR CLEANER

The 2020 CRF250R features a new air-cleaner element with both more surface area and more volume. The result? More power!

THROTTLE BODY

With a 44mm venturi designed to speed up airflow, the CRF250R’s throttle body really reaps benefits at low engine operating speeds. You get power and snap, right now.

HANDLING

SHOWA® SPRING FORK

The 49mm Showa® fork features a conventional spring design that helps increase the CRF250R’s front-suspension precision, handling and feel. The 39mm piston diameter and 25mm rod diameter guarantee a plush feel and supple action.

260mm FRONT BRAKE

The CRF250R’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.

DUNLOP MX3S TIRES

Developed using Dunlop’s latest “block-on-block” design technology, the CRF250R’s MX3S tires give excellent feedback and are a perfect complement to the CRF250R’s frame and suspension.

LOW REAR SHOCK MOUNT

With its low rear shock mount on the frame, the CRF250R benefits from both a lower center of gravity (cg) as well as chassis stability.

LOWER BATTERY MOUNTING

By relocating the battery 28.5mm lower for 2020, we’ve also lowered the CRF250R’s center of gravity—and that always helps overall handling.

NEW TWIN-SPAR ALUMINUM FRAME

The CRF250R’s latest twin-spar aluminum frame is identical to the CRF450R’s except for the lower engine cradle where the engine mounts. It’s the foundation for the 250’s superb handling.

NEW SHORT SWINGARM

The CRF250R’s short swingarm helps make it light, and also helps give the bike better rear-wheel traction, important considering how much power you have on tap. We shaved 160 grams off it this year too, so the design also reduces the bike’s unsprung mass.

COMFORT

BLACK RIMS

They may not help you go faster, but the sweet black DID DirtStar rims sure look good.

FLAT SEAT/TANK JUNCTION

The 2020 CRF250R features a flat seat/tank junction, including a titanium fuel tank. 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 CRF250R has you covered. Our redesigned “in mold” graphics look great, and stay looking good.

REAR SUBFRAME

The 2020 CRF250R’s subframe uses extruded rear members that produce a 20-percent reduction in weight versus the previous generation. Since that weight comes off the top of the bike, it also contributes to the CRF250R’s low center of gravity.

SMOOTH STYLING

Blending the CRF250R’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.
