2027 Honda CRF250R

Comfort & Convenience

• DETAILED BODYWORK MOUNTING: It may seem small, but every second counts when you’re servicing your bike between motos. Fewer mounting bolts mean enhanced serviceability at the track or in your garage.
• ELECTRIC START: To keep the bike light, our engineers use an electric starter with a lithium-ion battery.

Engineering

• HIGHER-CAPACITY RADIATOR: A large radiator provides the cooling capacity needed to sustain the engine's high power output.
• GEAR-POSITION ENGINE MAPPING: The smart ECU delivers tailored engine mapping for each gear, giving riders the edge and delivering optimal power with every shift.
• HONDA SELECTABLE TORQUE CONTROL (HSTC): Easily control your bike's traction with the left-side, handlebar-mounted green button. It activates our Honda Selectable Torque Control (HSTC) system, which offers three customizable settings to optimize your power delivery based on available conditions or rider preference.
• NINE-PLATE CLUTCH ASSEMBLY: An advanced nine-plate clutch design reduces slip at peak horsepower, improves torque transmission, and ensures greater longevity.
• WIDE WATER-PUMP GEAR: Making the water pump drive gear wide gives it a more tooth-engagement area for longer component life.
• 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 overall design compact.
• SPECIAL PRIMARY AND TRANSMISSION RATIOS: The bike has specialized primary and transmission ratios to handle more midrange power and torque without adding weight.
• TWO-LEAD SHIFT DRUM: The two-lead shift drum is designed to improve shifting across all gears, especially in the critical shift between second and third.
• "H" SECTION CRANK: The crankshaft has an "H" cross-section design, similar to a structural "I" beam. This design increases strength and reduces weight compared to traditional designs, which is crucial because it rotates at up to 14,000 rpm.
• LITHIUM-ION BATTERY: The bike’s Lithium-Ion battery is both super light and high-performing. It weighs less than half as much as a conventional lead-acid battery.
• SHARED ENGINE/GEARBOX LUBRICATION: A shared engine/transmission oiling design reduces weight and makes the engine more compact, particularly for the right-side cam drive and clutch placement.
• TITANIUM FUEL TANK: Every gram counts, so the bike 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 the fuel’s mass.
• LOWER SEAT / NARROWER BODY: We fine-tuned the seat height and bodywork width to make it easy to move around on the bike and enhance overall rider comfort.

Handling

• RESPONSIVE FRAME: A superior frame is crucial for excellent handling, and the chassis delivers. It's lightweight and responsive, with narrow main spars, and was designed with direct input from Honda HRC factory riders.
• SHOWA® SPRING FORK: The 49mm Showa fork uses a conventional spring design with a 39mm piston and a 25mm rod to give the rider a supple feel while still having the holdup needed to resist bottoming under heavy loads like big jumps, bumps, or ruts.
• TRIPLECLAMPS, AXLE, AND STEERING STEM: We tuned the tripleclamps, frame, fork, and steering stem for ideal chassis rigidity and responsiveness, giving the bike cornering feel for days.
• REAR SUSPENSION: Pro-Link® rear suspension offers 12.1 inches of travel and a lightweight spring for a plush and controlled ride.
• 260MM FRONT BRAKE: The front brake disc measures 260mm, providing excellent feel and weight reduction. A front brake-disc guard is also included.
• LOW BATTERY MOUNTING: Attention to detail is essential to keeping a bike’s center of gravity low. That’s why we located the battery as far down in the chassis as possible. It’s just another reason the bike handles so well.
• LOW REAR SHOCK MOUNT: With its rear shock mount low on the frame, the bike benefits from a lower center of gravity (CG) and greater handling stability.
• SHORT SWINGARM: A short swingarm helps keep the bike light and also improves rear-wheel traction. It reduces unsprung mass, which is important, considering how much power you have on tap.
• REAR SUBFRAME: The subframe uses extruded aluminum rear members to produce a lightweight design. Since that weight comes off the bike's top, it contributes to the low center of gravity.
• PIRELLI SCORPION MX32 TIRES: The CRF250R comes with the Pirelli Scorpion MX32 tires front and rear, designed for optimal grip and feedback across various track surfaces and conditions.

Performance

• DOHC ENGINE LAYOUT: With a unique finger-follower rocker design, the DOHC engine maximizes power and raises the redline, resulting in superior performance.
• SINGLE-MUFFLER EXHAUST: A pressed-alloy design lets us shape the muffler for better rider ergonomics and lighter weight.
• FUEL INJECTION SYSTEM: The 60-degree-angled fuel injector delivers a cooler, denser fuel charge, increasing power and torque. These meticulous details put this bike ahead of the competition.
• HIGH-PERFORMANCE CAM PROFILES: Drawing inspiration from our esteemed HRC factory team, we have meticulously crafted the cam profiles to enhance bottom-end torque and power without compromising the exhilarating peak performance.
• BIG BORE/SHORT STROKE: With a 79.0mm bore and short 50.9mm stroke, our engineers designed a high-revving engine with ample space for large valves, the core elements of power in motocross.
• DOWNDRAFT INTAKE AND EXHAUST LAYOUT: The DOHC cylinder-head design straightens intake and exhaust tracts for more efficient flow. It also boosts low-speed and midrange torque and throttle response.
• TITANIUM INTAKE AND EXHAUST VALVES: High-revving engines benefit from lightweight components, such as titanium valves, ovalized valve springs, and finger rockers treated with Diamond-Like Carbon (DLC) for durability.
• BRIDGED-BOX PISTON: The bridged-box piston design is the final piece of the engine performance package. It features a reinforcing structure between the skirts and wrist-pin bosses that helps enable a high redline.
• HIGH REDLINE: Our DOHC design and big-bore/short-stroke engine lead to an impressive rev limit, peak power, and peak torque.
• HIGH-VOLUME AIRBOX AND AIR CLEANER: The air-cleaner element has a large surface area and volume, and the airbox provides direct airflow to the engine, resulting in power throughout the rpm range.
• THROTTLE BODY: The throttle body, with a 44mm venturi designed to increase airflow, provides improved power and responsiveness at low engine speeds.

Style

• STYLING: For 2027, the livery features large horizontal Honda and CRF logos, plus blue side number plates and rear fender, creating a tri-color look that embodies the Honda HRC racing identity.
• SMOOTH BODYWORK: Blending the body panels enhances the bike's appearance and facilitates easier movement.
• BLACK RIMS: The DID DirtStar rims are lightweight and strong, while the black color looks good and is easy to clean.
• "IN-MOLD" GRAPHICS: Because it’s important to look your best while in the victory circle, our in-mold graphics are durable and visually appealing.

Technology

• HRC LAUNCH CONTROL: The ECU’s special launch control program lets you select the mode with the green button, hold the throttle open, and release the clutch. Your bike then takes control, regulating power to the rear wheel based on available traction and turning it into a holeshot-seeking machine!
• ENGINE MODE SELECT BUTTON: Customize your engine's power delivery with the convenient left-side, handlebar-mounted blue button. It allows you to effortlessly switch between Standard, Smooth, and Aggressive modes to suit varying track conditions or rider preference.
