WIN ON SUNDAY.

2019 Honda CRF450R: 

The industry’s best-selling motocross bike, victor at the 2018 Daytona Supercross at the hands of Team MotoConcept Honda’s Justin Brayton, and also winner of four media shootouts, the CRF450R receives a host of updates for 2019, making it lighter and more powerful. Because converting the “Absolute Holeshot” into moto wins requires more than just added performance, rider comfort has been increased through the addition of adjustable mounting positions for the new Renthal Fatbar® handlebar. With the 2019 CRF450R’s all-new black rims and its unique, in-mold graphics, celebrating on the podium never looked so good.

LAUNCH. HOLESHOT. PODIUM.

Heat after heat, race after race, Honda’s CRF450R is hooking up riders like never before. If there’s ever a machine that’s given you an almost uncanny holeshot advantage, this is it. And for 2019, we’ve taken this awesome open-classer and made it even better. How? For starters, it’s even lighter. Then there’s an all-new chassis and swingarm, designed to work together for increased traction and cornering. The engine features longer head pipes for better throttle response and top-end pull. New fuel-injection settings spray twice per cycle to better atomize the fuel. And for the first time ever, there’s a special launch-control setting, so it’s easier than ever to grab the holeshot and hang on to your lead. What else is new? Plenty. The 2019 CRF450R—better than ever.

Looking for the ultimate 450? Then check out our new CRF450R Works Edition. You get all the improvements of this year’s bike plus a special hand-ported cylinder head, black DID LT-X rims, exclusive Yoshimura mufflers, 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 full-on HRC decals. The only thing missing is a factory contract!

 

 

 

2019 Honda CRF450R Totalmotorcycle.com Key Features

Handling
Next-Generation Aluminum Frame
The CRF450R’s Next-Gen twin spar aluminum frame positions the rear shock’s mounting point lower, opening up the airbox area and contributing to a lower center 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’ve 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’ve 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 center for improved handling. It also allows for more air flow, and that equals added horsepower.

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 CRF450R 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. And 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 racebike 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 centralize 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, exclusive Yoshimura mufflers, 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’s 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 aluminum 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.

 

 

Honda Broadens CRF Lineup with Expansive New-Model Launch
Largest performance off-road release yet includes new models for diverse applications

During a recent “CRF Collective” unveiling ceremony at Fox Racing headquarters, Honda announced its most far-reaching range of performance off-road models ever, expanding the group by three and significantly improving the four returning models. Leveraging the brand’s unparalleled experience in the manufacture of dirt bikes, Honda’s performance off-road lineup now includes CRF machines for riding applications including motocross, closed-course off-road, pure off-road, and even dual sport.

All seven models are based on the platforms of Honda’s revolutionary motocrossers, the CRF450R and CRF250R. Those two machines return for 2019 but with important updates, as does the closed-course off-road CRF450RX. In addition, Honda is offering a factory-replica version of its full-size motocrosser called the CRF450RWE (“Works Edition”). The trail-ready CRF450X is entirely new for 2019, and it’s joined by a road-legal CRF450L that enables customers to connect trails via asphalt. Finally, Honda is also introducing an all-new CRF250RX closed-course off-road machine.

“Honda’s history in off-road is something we’re very proud of, from the ’70s-era Elsinores, through the XRs of the ’80s and ’90s, to the post-millennial CRF models,” said Lee Edmunds, American Honda’s Manager of Motorcycle Marketing Communications. “For 2019, it’s exciting to build on that reputation with the most expansive lineup of CRF performance off-road models ever offered, and to reach a wide range of enthusiasts through motorcycles that are tailored to an equally diverse spectrum of riding environments. With this new lineup, there really is a CRF off-road performance machine for everyone.”

CRF450L
The trails are calling, and the all-new road-legal CRF450L answers, expanding customers’ off-road possibilities by enabling access to the best riding trails, even when that means connecting them via asphalt roads. Street legality is achieved via features like LED lighting, mirrors, and a dedicated exhaust system. Equally at home in the woods or desert, the CRF450L has a wide-ratio six-speed transmission for maximum adaptability, while a lightweight, 2.0-gallon tank offers great range. Compared to the CRF450R motocrosser, crank mass is up for tractability in technical conditions, where a large-capacity radiator keeps things cool.

CRF450RWE
For the 2019 model year, you don’t have to be Ken Roczen to enjoy a CRF450R with factory enhancements, as the new CRF450RWE features a number of upgrades based on the bikes in the Team Honda HRC race shop. Rocketing to the top step of the podium through the use of a specially designed cylinder head with hand-polished ports, Yoshimura titanium slip-on muffler, and special ECU settings, this new model offers increased low- and mid-range torque. It also features the same graphics as Roczen’s No. 94 race bike, including a Throttle Jockey factory seat cover. Upgraded black D.I.D LT-X rims are included, along with black triple clamps and a gold RK chain. Titanium nitride-coated fork legs and an updated, titanium nitride-coated shock shaft increase traction and bump absorption.
