Handling

– Next-Generation Aluminum Frame: The CRF450R’s Next-Gen twin spar aluminium frame positions the rear shock's mounting point lower, opening up the airbox area and contributing to a lower centre of gravity for more holeshots. The frame geometry also helps improve traction, feeling and steering precision.

– Showa Spring Fork: The 49mm Showa fork features a conventional spring design that helps increase the CRF450R's front-suspension precision, handling and feel. The spring rate provides better bottoming resistance and improved handling.

– New Swingarm: We have changed the way we build the CRF450R's swingarm this year, fine-tuning the flex to work with the new chassis and give you better rear traction and cornering precision.

– New Frame Members: We have stiffened up the CRF450R's chassis to work better with the new swingarm. At the same time, we took some rigidity out of the rear subframe, to help maintain the bike's overall balance and feel.

– Twin-Muffler Exhaust System: The CRF450R'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 centre for improved handling. It also allows for more air flow, and that equals added horsepower.

Engineering

– HRC Launch Control: We are talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the CRF250RX 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: Kickstarting your bike is so 2016. By ditching the kickstarter entirely, our engineers can make the CRF450R lighter. Electric starters and lithium-ion batteries are so light now and so good that putting them on a bike like this is a win/win combination. Winning is what a CRF450R is all about.

– Lighter Overall Weight: We shaved an additional 1.75 pounds from this year's CRF450R—a surprise considering how light this bike already is. Where did it come from? Mostly from eliminating the kickstart option, but weight is weight, and on a race bike less of it is almost always better.

– 260mm Front Brake: The CRF450R'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.

– Titanium Fuel Tank: Grams and performance count, and the CRF450R uses a titanium fuel tank. Light and strong, it’s also thinner than our previous plastic unit, while maintaining the same capacity, freeing up more space and helping to centralise fuel mass.

– 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.

Performance

– All-New Works Edition: Homologated for racing and available in limited numbers, the CRF450RWE Works Edition includes all the improvements of this year's CRF450R plus a special hand-ported cylinder head, black DID LT-X rims, an exclusive Yoshimura muffler, titanium nitride-coated lower fork legs and shock shaft, an RK gold chain, special ECU settings, black triple clamps, revalved suspension, a factory-spec gripper seat and an HRC decal package.

– 449cc Unicam Engine: Honda's Unicam cylinder heads combine the best of single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity.

– Downdraft Fuel Injection: The CRF450R features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It is part of the reason the CRF450R offers such explosive power and massive torque, especially out of the starting gate and in the critical first 100 feet of the race to the first turn.

– New Double-Spray Injector Settings: The CRF450R'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 overrev — you'll feel it the first time you race.

– New Longer Head Pipes: Lengthening the CRF450R's headpipes help give you better throttle response and top-end pull.

– Dunlop MX3S Tires: Developed using Dunlop's latest "block-on-block" design technology, the CRF450R's MX3S tires give excellent feedback and are a perfect complement to the CRF450R's frame and suspension.

– Cylinder Head Layout: The CRF450R uses our latest finger-follower rocker design. The Unicam cylinder head remains one of the most efficient in the MX world, giving you the design and performance of a double-overhead-cam layout but the compactness of a single-overhead-cam design.

– 13.5:1 Compression Ratio: The CRF450R features a refined squish area that helps boost compression to an impressive 13.5:1. That means improved combustion efficiency for more power.

– "In Mold" Graphics: With the all the time you'll be spending in victory circle, you need to look your best. The 2019 CRF450R has you covered. Our "in mold" graphics look great, and stay looking good longer.

– New Programmable ECU: Want to fine-tune your CRF450R's power delivery to a specific riding style or track? It's easier than ever with the 2019 CRF450R's programmable ECU.

– Skid Plate: A factory skid plate is light and offers the engine and lower-frame protection that a racer demands.

Comfort

– New Renthal "Fatbar": The new aluminium Renthal Fatbar features a new bend too. The old Honda "CR" bend was legendary for getting it right and this new fat bar is even better. It's the new standard of excellence – you're gonna love it!

– Flat Seat/Tank Junction: The CRF450R 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.

– New Black Rims: They may not help you go faster, but the new black DID rims this year sure look good.

Engineering

– HRC Launch Control: We are 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 cannot 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). Ovalized valve springs and long-wearing Diamond-Like Carbon (DLC) treated finger rockers complete the package.

– 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 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 79mm 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.

– 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 horsepower.

– 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.

– Bridged-Box Piston: A first for a Honda MX bike, the CRF250R features a bridged-box piston design developed on our factory race bikes. Why? The reinforcing structure between the skirts and the wrist-pin bosses let's 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!

– 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.

– 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.

– Lithium-Iron-Phosphate Battery: Like the rest of the CRF250R, the bike's Lithium-Iron-Phosphate battery is both super light and high performing. In fact, it weighs less than half the weight of a conventional lead-acid battery.

– 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 2019 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.

Performance

– New 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 2019 Cam Profiles: With input directly from our HRC works team, we have changed the cam profiles on our 2019 model. You should feel the engine rev more freely, as well as improved torque feel in the bottom end.

– New Throttle Body: With a 2mm smaller venturi designed to speed up airflow, the CRF250R's new 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—33mm intakes and 26mm exhausts. Combined with the high lift, the twin-cam CRF250R flows a lot more, especially at high revs when you're wicking it up.

– 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 2019, feel free to hold that throttle open and head for the first turn—the CRF250R is designed to win that critical holeshot drag race as well as increased low-end torque.

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.

– 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 also reduces 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.

– 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.

Comfort

– 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.

– "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 "in mold" graphics look great, and stay looking good longer.

– Rear Subframe: The 2019 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 2019 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.

– New Black Rims: They may not help you go faster, but the new black DID rims sure look good.
