FLICK WITH EASE THROUGH THE TERRAIN.
2019 Honda CRF250RX:
Based on Honda’s successful 250cc motocrosser, the all-new CRF250RX is specially designed for closed-course off-road competition. Joining the CRF450RX in the quest for podiums in series like GNCC and WORCS, this off-road weapon features all of the same performance-driven features as the CRF250R, but adds off-road-specific features like a larger fuel tank, aluminum sidestand, and 18-inch rear wheel.
Ready for the biggest news the off-road riding community is going to hear this year? Introducing the all-new Honda CRF250RX, a high-performance trail/enduro machine built to exploit all the advantages a 250 has to offer. Bigger Baja bikes may get all the attention, but 250 riders know where their bikes really shine: on tight, technical trails that leave those big open-class riders panting and exhausted, while they use the light weight and maneuverability to flick through challenging terrain. So we’ve equipped the new CRF250RX with the same great engine and chassis as the CRF250R motocrosser, but added an 18-inch rear wheel, a bigger fuel tank, special suspension settings, a sidestand, and more. It’s all about giving you the best bike in the class.
2019 Honda CRF250RX Totalmotorcycle.com Key Features
New 2019 Cam Profiles
With input directly from our HRC works team, we’ve given the new CRF250RX the same cam profiles on our 2019 CRF250R. 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 CRF250RX’s new throttle body really reaps benefits at low engine operating speeds. You get power and snap, right now.
New Double-Spray Injector Settings
The CRF250RX’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 ride.
Large Valve Diameters
The CRF250RX’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 CRF250RX flows a lot more, especially at high revs when you’re wicking it up.
With our better-breathing DOHC design and the big-bore/short-stroke engine, the CRF250RX’s rev limit is way impressive. The same goes for peak power and peak torque.
Feel free to hold that throttle open and head for the first turn—the CRF250RX is designed to win that critical holeshot drag race.
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 CRF250RX will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!
The new CRF250RX 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.
DOHC Engine Layout
The CRF250RX 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.
High-Capacity Resin Fuel Tank
For longer enduro loops, the CRF250RX features a bigger fuel tank that holds a full 2.25 gallons.
New Gear-Position Engine Mapping
Talk about smart: The CRF250RX 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 CRF250RX 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 course conditions.
Titanium Intake and Exhaust Valves
Light is right when it comes to a high-revving engine’s reciprocating masses. That’s why the CRF250RX 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 CRF250RX’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 he tries to run while holding his 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 CRF250RX’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 breaths and revs—the two keys to making power in the enduro world.
The CRF250RX’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.
The new CRF250RX 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 CRF250RX’s high redline.
“H” Section Crank
Look closely at the CRF250RX’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 CRF250RX’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 CRF250RX’s center of mass for superior handling.
Clutch Design and Materials
The CRF250RX’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.
Like the rest of the CRF250RX, 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.
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 CRF250RX’s overall design compact.
Shared Engine/Gearbox Lubrication
The 2019 CRF250RX 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.
Low Rear Shock Mount
With its low rear shock mount on the frame, the CRF250RX benefits from both a lower center of gravity (cg) as well as chassis stability.
Showa Spring Fork
The 49mm Showa fork features a conventional spring design that helps increase the CRF250RX’s front-suspension precision, handling and feel. The 39mm piston diameter and 25mm rod diameter guarantee a plush feel and supple action.
The CRF250RX’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 Geomax Tires
The CRF250RX’s Dunlop Geomax tires are specially designed for enduro use. The AT81 tires are spec’d at 80/100-21 for the front and 110/100-18 for the rear. You read that right: the CRF250RX rolls on an 18-inch rear wheel.
260mm Front Brake
The CRF250RX’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.
Blending the CRF250RX’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 CRF250RX has you covered. Our “in mold” graphics look great, and stay looking good longer.
The 2019 CRF250RX’s subframe uses extruded rear members that produce a 20-percent reduction in weight versus the previous generation CRF250R. Since that weight comes off the top of the bike, it also contributes to the CRF250RX’s low center of gravity.
Flat Seat/Tank Junction
The 2019 CRF250RX 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.
They may not help you go faster, but the sweet black DID rims sure look good.
Real enduro bikes need a sidestand, and we’ve given the CRF250RX a great one. Tucked up high and out of the way, this forged alloy piece is just another example of how the CRF250RX gets it right.
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.”
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.
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.
Already the industry’s top-selling motocrosser and the winner of the 2018 Daytona Supercross at the hands of MotoConcept’s Justin Brayton, the CRF450R receives a number of important updates for 2019. Better engine performance is achieved through a new combustion-chamber shape, as well as improved over-rev characteristics through a refined oil-management system. The frame and swingarm have been revised for optimized rigidity and weight reduction, while the braking system has been updated with a lightweight front brake caliper featuring a large-piston design. As a result of the weight-saving measures, the CRF450R is 1.76 lbs. lighter than its predecessor. For added performance and increased comfort, the 2019 model features new ECU settings, HRC launch control, a Renthal Fatbar® handlebar and adjustable handlebar position. Black rims and redesigned fork protectors are also new. This is how you convert the “Absolute Holeshot” into moto wins.
Having featured heavily in Honda-mounted teams winning 20 of the last 21 Baja 1000s, the CRF450X gets a complete overhaul for 2019, based on the modern CRF platform but with off-road-appropriate features. A true off-road machine that’s ready for racing or trail riding, this model features a headlight, taillight, and side stand, as well as an 18″ rear wheel and lightweight 2.0-gallon fuel tank. For maximum versatility in challenging terrain, the CRF450X also features a 49mm Showa fork with dedicated settings, wide-ratio six-speed transmission, and higher crank mass than the CRF450R.
Currently campaigned by JCR Honda’s Trevor Bollinger and Trevor Stewart in GNCC and WORCS competition, respectively, the CRF450RX inherits the same performance-enhancing features of the 2019 CRF450R, including an updated cylinder head and refined oil-management system, while still featuring off-road-specific features like a 2.2-gallon resin fuel tank, 18-inch rear wheel, and aluminum side stand. Suspension is specially tailored to the CRF450RX and uses low-friction fork oil. For added performance and increased comfort, the 2019 model features new ECU settings, HRC launch control, a Renthal Fatbar handlebar, and adjustable handlebar position. Black rims and redesigned fork protectors are also new.
Based on Honda’s successful 250cc motocrosser, the all-new CRF250RX joins the CRF450RX as a weapon for closed-course off-road competitions throughout America. Equipped with a larger-capacity, 2.2-gallon resin fuel tank, 18-inch rear wheel, and aluminum side stand, the RX makes quick work of challenging situations, its dedicated suspension and ECU settings helping the rider work through even the toughest trail sections. As with the CRF250R, HRC launch control, a Renthal Fatbar handlebar, and black rims are standard.
Newly introduced in 2018, the CRF250R has seen the GEICO Honda and TiLube Honda teams earn multiple wins in AMA Supercross and Arenacross competition, respectively, while also achieving success in amateur national races. For 2019, the model is revised with increased low-to-midrange engine performance for improved corner exiting. Inspired by the factory version, the Double Overhead Cam engine features updated cam profiles and intake- and exhaust-port profiles, a 50mm shorter right exhaust pipe, and a 2mm smaller throttle body. Riders can select from three engine modes for ideal performance depending on conditions, while HRC launch control has been adopted for improved race-start performance. A Renthal Fatbar handlebar sits in a four-position-adjustable top clamp, while the braking system has been updated with a lighter, CRF450R-inspired caliper with larger piston for optimum braking performance. Black rims are standard.
CRF150R / CRF150RB
Raced by Amsoil Honda hotshot Hunter Yoder on the amateur national circuit, Honda’s smallest motocross machine returns for 2019, featuring a Unicam four-stroke engine that offers a spread of ample, useable power and torque across the rev range. Suspension duties are handled by Showa, with a 37mm inverted fork and Pro-Link rear link system. In addition to the standard version, Honda offers the CRF150RB, which features larger wheels, a taller seat, a longer swingarm, and more rear-suspension travel.
