ENGINEERING

NINE-PLATE CLUTCH ASSEMBLY

The CRF250R uses a nine-plate design to improve durability and hookup. That helps eliminate 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.

HYDRAULIC CLUTCH

The CRF250RWE features a new, hydraulically actuated clutch like our 450s do. Made by Nissin, it’s the same design as in our Grand Prix MX machines. You get a clutch-lever pull that’s ten percent lighter at its peak and more consistent throughout an entire moto. Plus, you’ll never have to worry about making a clutch-cable adjustment, even during the longest events.

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.

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 lets 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. The straighter ports also help boost low-speed and midrange torque as well as throttle response.

SINGLE-PIPE EXHAUST

The CRF250R uses a single-pipe header. It routes close to the center of the bike, and its light overall construction helps improve weight distribution. The single muffler uses a pressed-alloy design that lets us shape the muffler body for better rider ergonomics and lighter weight.

WIDE WATER-PUMP DRIVE GEARS

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

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 or rider preference.

ENGINE OIL SCAVENGE PUMP

Deep in the engine, there’s a special oil scavenge pump that we’ve designed to be especially small and out of the way. While you may never see it, it helps keep the CRF250R’s overall design compact.

SPECIAL PRIMARY AND TRANSMISSION RATIOS

To handle more broad midrange power and torque, the CRF250R gets special primary and transmission ratios. The ratios let our engineers use the same shaft centerlines as the previous design, so the transmission itself remains light and compact.

TWO-LEAD SHIFT DRUM

By changing from three to two lead tracks on the shift drum, we improved the shift feel between second and third gears.

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.

"H" SECTION CRANK

Look closely at the CRF250R’s crankshaft profile and you’ll see its “H” cross-section design. 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 2025 CRF250R uses a shared engine/transmission oiling design. 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 2025 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, doubled intake 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.

LOWER SEAT/NARROWER BODY

Fine tuning the seat height and narrowing the bodywork makes it easier for you to move around on the bike and help enhance rider comfort.

TECHNOLOGY

HRC LAUNCH CONTROL

We’re talking about a special ECU program here: push the starter 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. The lights on the left handlebar cluster tells you when it's activated. It turns your bike into a holeshot-seeking machine!

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

EXCLUSIVE WORKS EDITION

Simply stated, the best of the best. The CRF250RWE Works Edition includes all the standard CRF250R features, but also gets a new, exclusive hydraulic clutch, special hand-ported cylinder head; Hinson clutch basket and cover; Twin Air filter, Throttle Jockey graphics and seat cover; upgraded DID DirtStar LT-X rims; an exclusive Yoshimura exhaust system including a titanium midpipe and muffler; titanium oxide-coated lower fork legs; revalved suspension; a DID gold chain; special ECU settings; and black triple clamps.

FUEL INJECTION

By installing the CRF250R’s 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. It’s little details like this that put the CRF250R up front.

BRIDGED-BOX PISTON

The CRF250R’s bridged-box piston is the 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 CRF250R’s high redline.

HIGH REDLINE

Our better-breathing DOHC design and big-bore/short-stroke engine mean the CRF250R features a high redline and impressive peak power and peak torque.

HIGHER-CAPACITY RADIATOR

When you’re making big power and riding long motos, you need plenty of radiator capacity to keep your engine running strong. No worries—the 2025 CRF250R features six percent more radiator area than the earlier generation’s design.

HIGH-PERFORMANCE CAM PROFILES

With input directly from our HRC factory team, we’ve given the CRF250R cam profiles that help the engine produce better bottom end torque and power, while still retaining the CRF250R’s screaming peak.

HIGH-VOLUME AIRBOX AND AIR CLEANER

The 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 the previous generation's design. More air equals more power, especially in the midrange. In addition, we’ve made it easier to service the air filter too.

MORE POWER

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.

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.

YOSHIMURA EXHAUST

The CRF250RWE’s exhaust is another premium item. It uses a stainless header along with a titanium midpipe and muffler made specially for us by Yoshimura. Super light and super trick, the exhaust tucks away for better ergonomics too.

HANDLING

NEW FRAME

Great handling starts with a superior frame, and that’s one place where the CRF250R chassis puts you out front. First, it’s light. By making the frame’s main spars narrow, we save weight, but more importantly we make the chassis more responsive. This year approximately 70 percent of the frame components are new for excellent, responsive turning performance and to work with the new suspension.

NEW TRIPLECLAMPS, AXLE, AND STEERING STEM

The CRF250R is a perfectly matched package. New top and bottom tripleclamps for 2025 work with the new frame, revised fork, new front axle and new steering stem for a more consistent suspension feel throughout the stroke. Working in concert, they help improve and balance total rigidity, responsiveness and turning performance.

SHOWA® SPRING FORK

The 49mm Showa® fork features a conventional spring design that helps increase the CRF250R’s front-suspension precision, handling and feel. For 2025, new springs, new seals and new valving improve the consistency of the stroke feel throughout the entire range of travel. Plus, on the CRF250RWE, the fork legs have a special titanium oxide coating, and the outer tubes are Kashima coated.

REAR SUSPENSION

The CRF250R’s frame design lets us fit a special rear shock. The shock’s valving resets fast for better response. In addition, it features a special steel spring that cuts weight without cutting performance. With the RWE, you get additional special A-Kit shock tuning and valving.

SINGLE EXHAUST ROUTING

The CRF250R’s single-pipe exhaust lets you move more freely on the bike. By tucking it in unobtrusively, it makes moving around on the bike easier than ever.

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, and for 2025 and a new front-brake caliper and piston seals give you more linear front-brake performance with less lever play.

LOWER BATTERY MOUNTING

To keep a bike’s center of gravity low, you need to pay attention to all the details. That’s why we locate the CRF250R’s battery low in the chassis. It’s just another reason why the bike handles so well.

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.

PIRELLI SCOPRION TIRES

The 2025 CRF250R comes equipped with Pirelli Scorpion MX32 tires front and rear. The tread patterns and compounds are designed to offer good grip and feedback in a wide range of conditions and track surfaces.

SPECIAL CRF250RWE TIRES

Along with all its other premium touches, the 2025 CRF250RWE comes equipped with Dunlop Geomax MX33 tires front and rear. We know you’re going to love the traction and ride they provide!

SHORT SWINGARM

The CRF250R’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.

REAR SUBFRAME

The 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 improved low center of gravity.

STYLING

DETAILED BODYWORK MOUNTING

It may seem like a small thing, but every second counts when you’re servicing your bike between motos. Fewer bolts mean enhanced serviceability, at the track or in your garage.

NEW “STACKED” CRF LOGO

Just like our factory racebikes, our 2025 CRF competition lineup features new vertically stacked CRF logo that really stands out on the track.

"IN MOLD" GRAPHICS

With all the time you’ll be spending in victory circle, you need to look your best. The CRF250R has you covered. Our “in mold” graphics look great, and stay looking good.

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.
