For the 2021 model year, Phoenix Racing Honda rider Kyle Peters will be able to use the same equipment that helped him win the AMA Arena cross Championship in 2020. Chase Sexton of GEICO Honda currently holds the 250SX East championship lead after six rounds on his CRF250R-powered bike in the 2020 AMA Supercross circuit.
Heroic podium speeches begin with heroic holeshots; if you aren’t ready to play as soon as the gate lowers, your opponents will devour your lunch. The Honda CRF250R is the best motorcycle for you to ride because of this. To feed your roost, you’ll have to provide the remainder of the field yourself. DOHC engine is capable of high revs. Twin-spar aluminum chassis with fine-tuning. Fit, quality, and attention to detail are similar to what you’d find on a factory bike. It is only the beginning of a long list. It’s an all-in-one product that’s ready to go straight out of the box. To be successful, you need the appropriate rider, and you’re that rider, right?
Honda CRF250R 2021 Dirt Bike – Feature
Push the button to pick the setting, keep the throttle open, and let go of the clutch, and the CRF250R will take care of the rest, giving you a huge head start into the first corner. Your bike becomes a holeshot-seeking machine!
Big Bore/Short Stroke
For our engineers, the CRF250R’s short 50.9-inch stroke allowed them to construct an engine with plenty of capacity for massive valves. In the motocross realm, power is generated by the engine’s ability to exhale and rev at high RPMs.
Clutch Design and Materials
The CRF250R’s clutch is made up of two different materials. Why? The clutch doesn’t need to become much bigger to manage the extra power the engine puts off. An engine’s maximum rpm is closely correlated to its spinning mass, which is lighter. The increased power demands need stronger clutch springs.
DOHC Engine Layout
In the CRF250R, a novel finger-follower rocker design is used in the DOHC engine arrangement. You gain more power and a higher redline when the engine’s architecture (bore and stroke, intake tract, piston, etc.) is combined.
Downdraft Intake and Exhaust Layout
Our engineers could better align the intake and exhaust systems on the CRF250R thanks to the DOHC cylinder head design. The exhaust is more efficient, too, thanks to the shorter, almost arrow-straight intake. It’s impossible to win a sprint race while holding your breath, and the same is true for your motorcycle’s engine. Both power and throttle responsiveness will improve.
Refined Dual-Exhaust System
CRF250R’s exhaust system is small, compact, and positioned close and low in the frame to remove weight from its rear end and increase the bike’s center of gravity for better control. The length of the pipes has been adjusted to provide you with greater low- and mid-end torque.
Engine Mode Select Button
The engine power delivery character may be adjusted with a simple thumb press on this handlebar-mounted button. If the track is smooth or rough, you may go with a standard-setting.
Engine Oil Scavenge Pump
The engine has a unique pump for scavenging oil. The CRF250R’s overall design is more compact because of it.
Gear-Position Engine Mapping
The CRF250R’s ECU has specific engine programming for each gear, making it very intelligent. One thing that sets CRF250R riders apart from the competition is their engine’s ability to generate superior power at each gear change.
Gradual Pipe-Bend Radius
Observe how the CRF250R’s two exhaust pipes curve out of the head in a slow, greater-radius fashion before returning to the new mufflers in a straight line. With the CRF250R’s low mass and twin-silencer design, the exhaust pipes and their ability to dissipate mass are crucial to improving performance and handling.
“H” Section Crank
See the “H” cross-section design in the CRF250R’s crankshaft profile. What’s going on here? “I” beams in airplane wings and skyscrapers improve strength and decrease weight over a standard crankshaft shape—a significant thing when you consider that this section switches at more than 14,000 rpm! ”
The CRF250R’s Lithium-Ion battery is lightweight and powerful, much like the rest of the bike. It’s lighter than a standard lead-acid battery by more than a factor of two.
Shared Engine/Gearbox Lubrication
There is a single oiling system for both the engine and gearbox on the CRF250R in 2021. Why? Having both systems work together reduces the engine’s overall weight while also allowing the right-side cam drive and clutch to be placed closer together.
Titanium Fuel Tank
The 2021 CRF250R sports a titanium fuel tank since every gram matters on a bike in the 250 class. It’s smaller and lighter than our old plastic unit, allowing us to save more room and better distribute the bulk of the gasoline.
Titanium Intake And Exhaust Valves
The responding masses of a high-revving engine should be light. It is why the titanium intake and exhaust valves of the CRF250R are used. In addition, the valve has an insignificant 20.5-degree angle (included). The DLC-treated finger rockers and ovalized valve springs complete the outfit.
Total Air Management
The term “total air management” denotes all aspects of airflow, containing intake, head, and exhaust. Eliminate the losses in one area, and you’ll gain power everywhere else. Isn’t it the best? It’s free power—all the rider need is a well-designed bike.
Convenience’s Electric Start
The electronic starter on the CRF250R is a breeze to use. For those times when you need to jump-start a stopped bike amid battle, this is a life-saver.
Performance Double-Spray Injector Settings
There are two fuel injection cycles per intake cycle on the CRF250R. By eliminating the need for a second injector, fuel atomization may be improved without introducing additional bulk or complexity. In the mid-range and on the over-rev, you’ll notice a noticeable increase in power.
To round out the CRF250R’s engine performance, a bridged-box piston is used. The CRF250R’s high redline is made possible by a strengthening component between the skirts and wrist-pin bosses.
High Capacity Radiator
When your engine is working hard, and you’re going long distances on your motorcycle, you’ll need a lot of radiator capacity to keep it cool. No worries, the CRF250R has you covered there.
This motorcycle’s top speed is astounding, thanks to the CRF250R’s big-bore/short-stroke engine and improved DOHC architecture. Peak torque and power are the same.
High-Volume Air Cleaner
There is a lot of surface area and volume in the air cleaner element on the CRF250R 2021 model. Is this what you came up with? Keep up the excellent work!
High-Performance Cam Profiles
HRC factory team feedback helped us design the CRF250R cam profiles that improve bottom-end torque and power while maintaining the CRF250R’s high-end scream.
Hold the throttle wide open and charge into the first corner on the CRF250R—built to take the crucial holeshot in a drag race. You’ll also notice a boost in torque from the low to mid-range.
The CRF250R’s throttle body benefits greatly from the engine’s low operating speeds thanks to a 44mm venturi that increases airflow. Right now, you’ll be able to unleash your full potential.
Handling Showa® Spring Fork
The traditional spring design of the Showa® 49mm fork aids in improving the front suspension accuracy, handling, and feel on the CRF250R. The supple action and plush feel are ensured by the 39mm piston and 25mm rod diameters.
260mm Front Brake
The front-brake disc on the CRF250R is a staggering 260mm in diameter. You get an excellent feel for the brakes, as well as a design that reduces weight. The set includes front and rear brake-disc protectors.
Dunlop MX3S Tires
The MX3S tires for the CRF250R were developed utilizing Dunlop’s newest “block-on-block” design technology and provide superb feedback, complementing the frame and suspension of the motorcycle perfectly.
Low Battery Mounting
You must pay close attention to every aspect if you want to maintain your bike’s center of gravity as low as possible. Because of this, the CRF250R’s battery is situated down in the chassis. It just adds to the bike’s overall agility.
Low Rear Shock Mount
The CRF250R features a lower center of gravity (CG) because of its low rear shock position on the frame.
Short Swing Arm
Due to its shorter swingarm, the CRF250R has superior rear-wheel traction and less unsprung mass, both of which are vital when dealing with so much power.
Twin-Spar Aluminum Frame
Aside from the lower engine cradle, the CRF250R’s new twin-spar aluminum frame is almost similar to the CRF450R’s. As a result, the 250’s agile handling is made possible.
