- 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!
- 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.
- New Gear-Position Engine Mapping: Talk about smart: The CRF250R now 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.
- 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.
- 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.
- 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).
- Downdraft Intake and Exhaust Layout: The DOHC cylinder-head design let our engineers straighten out the CRF250R's intake and exhaust tracts that have been optimized to improve power and response. The intake is shorter 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.
- Big Bore/Short Stroke: The CRF250R's 79 mm bore and short 50.9 mm 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.
- 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. It also allows for more airflow, and that equals added power. For 2020, the exhaust resonator has been removed
- Total Air Management: A 9% increase in air filter size for improved air flow and 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 power—you just need a bike with smart design.
- Bridged-Box Piston: A first for a Honda MX bike, the CRF250R features a bridged-box piston design developed on our factory racebikes. Why? The reinforcing structure between the skirts and the wrist-pin bosses lets this big-bore piston retain a light, strong construction and helps enable the CRF250R's high redline.
- “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!
- 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, with an improved capacity of 18% for added durability. The lighter rotating weight is directly related to how fast the engine revs.
- 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.
- Lithium-Iron-Phosphate Battery: Like the rest of the CRF250R, the bike's Lithium-Iron-Phosphate battery is both super light and high performing, weighing in at less than half the weight of a conventional lead-acid battery. The battery box position has been lowered by 28.5 mm, allowing for a larger air filter and lower centre of gravity (or improved mass centralization).
- Titanium Fuel Tank: Every gram counts on a bike in the 250 class, which is why the 2019 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.
- 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.
- Shared Engine/Gearbox Lubrication: The 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.
- 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.
- 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 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.
- Throttle Body: With a 44 mm 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.
- Large Valve Diameters: The CRF250R's valves don't just have impressive lift, the valves themselves are large-diameter too—33 mm intakes and 26 mm exhausts. Combined with the high lift, the twin-cam CRF250R flows a lot more, especially at high revs when you're wicking it up.
- Rad Capacity: 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.
- Showa Spring Fork: The 49 mm Showa fork features a conventional spring design that helps increase the CRF250R's front-suspension precision, handling and feel. The 39 mm piston diameter and 25 mm rod diameter guarantee a plush feel and supple action.
- 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.
- 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. The design has been updated and weight has been reduced by 160 grams for improved stability and handling, while still reducing the bike's unsprung mass.
- 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.
- 260 mm Front Brake: The CRF250R's large front-brake disc measures a whopping 260 mm, with improved rear brakes that perform like never before. 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.
- 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.
- 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 low center of gravity.
- Flat Seat/Tank Junction: The 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.
- Black Rims: They may not help you go faster, but the black DID® rims sure look good.
