Q: FIRST OF ALL, IS THE 2021 HONDA CRF250 BETTER THAN THE 2020 CRF250?
ONE:Is this deja vu? Why does the 2021 CRF250 look identical to the 2020 CRF250? Because it is, right down to the graphics. Honda has done this before. We said this in our 2017 CRF250 test: “If you put a 2017 Honda CRF250 and a 2016 Honda CRF250 in Honda's R&D department and asked Honda's most brilliant designer to tell 2017 from 2016, he couldn't to do it". There is a pattern here, but it doesn't make sense. Both years Honda made zero changes to the 2017 and 2021 CRF250s, it came out with an all-new CRF450. By not spending money on the 2021 CRF250, Honda was able to spend every penny of the R&D budget on the redesigned CRF450. Yes, let the CRF250s dry out. It's a strange business model to abandon the CRF250 in hopes of making it up with the CRF450. Is this business strategy working? Yes and no. There is a lot of buzz about the all-new CRF450, which should translate into increased sales in 2021. On the other hand, there is no buzz about the “Dolly the clone” CRF250 from last year. This is self-sabotage. Has Honda not realized that a modest effort to spice up your models with bold new graphics goes a long way in the eyes of the buyer? I do not think.
Q: WHAT HAS HONDA DONE TO THEIR CRF250 SINCE THE 2018 RESTORATION?
ONE:Honda had no choice but to spend millions of R&D dollars trying to fix the then all-new 2018 CRF250. It was a failure. The bike was a mess in the engine department. It handled well, but in the 250 class it's all about power, baby! The 2018 CRF250 offered no bottom or midrange, and top-end power was lower at 40.70 ponies. That's down 3-1/2 horsepower compared to the class leader, which in 2018 was the Husky FC250. The best word to describe the 2018 CRF250 was “boring”. The lackluster power made us feel like we were riding with the rear brake on. We checked multiple times to make sure we weren't.
Honda went straight to the design to see where things went wrong. The engineers couldn't start from scratch again like they did for the 2018 CRF250, as Honda's accountants wouldn't allow it. The budget for the CRF250 was already spent. So Honda had to pull money from somewhere else. Engineers were stuck trying to find ways to improve the CRF250 powerband on a tiny R&D budget. Here's a list of what Honda changed to the CRF250 in 2019 and 2020.
(1) Camera profile.For both 2019 and 2020, Honda changed the cam profile. Although the 2019 cam was developed by the HRC 250 Grand Prix racing team in Europe, it wasn't as good as the one developed by the in-house testers for the 2020 model.
(2) Exhaust ports.For 2019, Honda changed the geometry of both the intake and exhaust ports to move the power.
(3) Muffler.In 2019, the right side exhaust pipe was shortened by 50mm and in 2020 the muffler got larger perf core perforations.
(4) Head tube.In 2020, the resonator on the right head was removed for improved flow and the diameter of the head tube was reduced.
(5) Ignition timing.In 2020, the timing was updated to 8000 rpm.
(6) Engine cooling.In 2019, Honda realized they needed to lower engine temperatures. Engineers did this by adding a nozzle to the piston's oil jet and widened the left-side radiator by 5 percent at the top.
(7) AC generator.The AC generator was redesigned to reduce weight and friction loss in 2019.
(8) Clutch.The weak 2018 clutch was updated in 2019 and 2020. In 2019, it received an updated basket and judder spring used in the 2018 recall, and in 2020 the clutch plates became thicker, the clutch springs became stiffer, and the oil or capacity increased by 18%.
(9) Piston.In 2019, the bridged box piston design featured a reinforcing structure between the legs and wrist heads.
(10) Butterfly body.A smaller 44mm Keihin throttle body replaced the 46mm throttle body in 2019.
(11) Sensor.In 2020, a transmission position sensor was added to allow different ignition maps for each of the five speeds.
(12) Transmission.Second gear became taller in 2020 (going from 1.80 to 1.75 ratio) and second and third gears were treated with WPC.
The 2021 Honda CRF250 is the 2020 CRF250.
Q: DID THE CRF250 ENGINE GET BETTER WITH ALL THE CHANGES FROM 2018 TO 2020?
ONE:Yes. All the engine updates made in 2019 and 2020 made a big difference on the track. The engine made more power all around the dyno curve than the 2018 model. In 2020, the CRF250 produced 42.98 horsepower at 13,800 rpm, which was over a 2-pony improvement from 2018. It sounds good number, right? In 2018, we'd say yes. However, when Honda was caught behind the eight ball, the other manufacturers smelled blood and developed improved machines for 2020. The CRF250 placed fourth in peak power in 2020, ahead of the Yamaha YZ250F and the already aging Suzuki RM-Z250 .
Testers enjoyed riding the CRF250 with its improved powerband. It was easy to drive as long as you kept the momentum moving forward and were in the right gear. That was the problem
When theMXATest riders stacked it against the blue, orange, white and green bikes, the fun stopped there. The CRF250 is not a competitive machine when pitted against its competition.
Q: WHAT WILL YOU LIKE ABOUT THE 2021 CRF250?
ONE:The handling. This is one of the best handling bikes in the 250 four-stroke class. It suits a wide range of riders. The suspension is reminiscent of the Kayaba SSS components. How come? Because most riders can jump on the bike and feel right at home with minimal changes. For riders who lack the knowledge and experience to set up their own bikes, the CRF250 and YZ250F are almost unbeatable. It's hard to get it wrong.
The Showa suspension is plush, really plush. The suspension is on the soft side and the forks dive at times. However, they are hard to pin down. While the plush forks have a lot of travel, do they soak up rough terrain in their path? For most riders, too much movement is not a bad thing. It felt like we were driving on cloud nine. We could relax our grip on the bars and enjoy the ride. Pro test riders prefer more input from the ground and less back and forth motion. Faster testers wanted harder settings.
What helps the plush suspension is the frame it's attached to. The CRF250 frame does not flex under load, which improves suspension characteristics and cornering consistency. Like its big brother, the CRF450, it has excellent cornering characteristics, but while the CRF450 wants to stand tall at the apex of the corner, the CRF250 digs in and stays planted. This is a bike that turns with precision, albeit at a cost. At speed, the bike will rock for our lighter test riders. Bigger and stronger testers could handle it.
Q: HOW DOES THE BIKE STAKE UP AGAINST ITS COMPETITION IN 2021?
ONE:Japanese manufacturers must have made a deal a long time ago about production cycles to save money. Doesn't it seem odd to you that Honda, Kawasaki, Suzuki and Yamaha would follow four year production cycles? This means that every four years they would come out with a brand new bike. Sure, little things would change over that four-year span with updated suspension settings, different gear ratios, new tires or fancy graphics, but engine overhauls or chassis changes were neutralized by the powers that be. The four-year production cycle worked great when the only players were Yamaha, Kawasaki, Suzuki and Honda. Budgets could be set in advance and everyone knew when each other's new models were coming out. Everything was going smoothly until KTM pulled the rug out from under the Japanese manufacturers. KTM disrupted the industry by updating bikes whenever they wanted to. They really threw a wrench into the four-year production cycles of Japanese manufacturers. Even worse for the Big Four was that KTM came out with the KTM 450SXF Factory Editions in 2012. This scared the Japanese, because this was a brand new model that had been on the show in just six months
Since then, the Japanese brands have been playing catch-up with the Austrian juggernaut, who not only came out with new engines whenever he wanted, but grew from one brand to three brands (KTM, Husqvarna and GasGas). All three were serious competition, because they were all built with serious components. What does this mean for the 2021 Honda CRF250? It means that not only will they be a year behind Yamaha and Kawasaki in 250 development, but they will be two to three years behind the Austrian trio. Honda's stagnation on the CRF250 gave the competition a chance to strike.
The 2021 CRF250 offers a decent power package, but it doesn't shine in any area of the power curve. It's still lethargic off the bottom, needs a wake-up call from the clutch in mid-range, and is starting to wake up from its nap in the upper echelons of the powerband. This is a long, drawn out process. It takes precious time to get into the meat of power. By the time the CRF250 wakes up, the 250SXF, FC250, YZ250F and KX250 are long gone. Even the dated RM-Z250 can challenge the CRF250 in the right environment, which consists of tight, clay, or Supercross-style tracks.
The writing is on the wall. Honda put the 2021 CRF250 in a hole as deep as the Chuquicamata open pit mine (the world's largest man-made hole). From 2018 to 2020, Honda did a pretty good job with what they had to work with. Power boosted and powerband widened. These 2019 and 2020 Band-Aid fixes made the CRF250 easy to ride for the masses—though the RM-Z250, YZ250F, and FC250 are also easy to ride.
Q: WHAT DO WE HATE?
ONE:The Hate List:
(1) Power zone.The CRF250 makes decent power on the dyno, but on the track the power is slow. By the time he picks up speed, the competition has already passed.
(2) Weight.At 228 pounds, the CRF250 wouldn't even be the lightest bike in the 450 class. It's 10 pounds heavier than the lightest 250 four-stroke and 5 pounds heavier than the lightest 450 (both are KTMs).
(3) Engine covers.The paint on the ignition and clutch cover is scratched on the first ride.
(4) Maps.We want a more distinct difference between the three CRF250 maps. Most testers couldn't feel much of a difference.
(5) Dual exhaust.Unlike the CRF450's one-to-two dual exhaust (gone for 2021), the CRF250 actually has two separate exhaust pipes and mufflers running on either side of the bike. If the CRF250 had the best power in the class, we could overlook the complexity, weight, and cost of replacing the two pipes, but it doesn't.
(6) Rear fender.The rear fender is weak and will eventually break if you grab it to lift the bike onto the stand. We lift it from the hot muffler.
(7) Titanium gas tank.Making the gas tank out of titanium and then covering it with plastic is like wearing suspenders to hold your belt up. At least if we could see more than a small piece of titanium it would have a cool factor.
Q: WHAT DID WE LIKE?
ONE:The list of similar:
(1) Handling.This is the best feature of the CRF250. It doesn't wiggle or wiggle, and it turns on a dime - although it will rock at speed in the rough.
(2) Suspension.Showa parts are fake. It's hard to find a bad setup.
(3) Clutch.Stiffer springs, better fiber plates and additional oil added in 2020 turned a weak clutch into something to be proud of.
(4) Front brake.This is a good front brake, maybe not Brembo but it will do the job.
Q: WHAT DO YOU REALLY THINK?
ONE:Let's start by saying that the 2021 CRF250 is a good bike. It doesn't do anything catastrophically wrong. it just doesn't do anything great. It has an excellent frame with pleasant suspension attached to it. It offers a clutch that works, brakes that stop and an engine that has a powerband without dips or valleys. Its cockpit is compact and better suited to shorter riders. The 2021 CRF250 is an easy bike to get comfortable with. Younger riders jumping to big bikes or lower level riders will appreciate the CRF250. On the other side of the coin, serious racers will overlook the top handling and plush suspension and focus on its worldly engine. If you're a serious racer, you'll need to drop at least a few thousand dollars on the CRF250 just to make it competitive with stock engines from other brands.
The CRF250 is a great bike for new riders or minibike riders making the jump to big bikes. It handles well and the suspension is great for lighter riders.
2021 HONDA CRF250 MXA SETUP SPECS
Here's how we set up the 2021 Honda CRF250 for racing. We offer this as a guide to help you find your own sweet spot.
SHOWA A-KIT SPRING FORKS
Honda hit the nail on the head with the valve and spring rates on the Showa coil spring forks for the majority of 250 four-stroke riders. With the stock settings, the forks were lowered to their stroke. we added some compression clicks to allow them to climb higher. Some of the riders also dropped the forks in the clamps by 2mm to reduce oversteer. If you are experiencing oversteer, drop the slack first, then drop the forks. For hardcore racing, these areMXARecommended 2019 CRF250 Fork Settings (stock settings are in parentheses):
Spring rate:4,8 N/mm
Compression:7 clicks out (9 clicks out)
Rebound:12 clicks out
Fork-leg height:3 mm
Notes:The forks worked well for the standard 250 four-stroke racer. Ride these forks before you send them to your suspension guru. You might just be surprised at how well these forks work for your weight and skill level. If your head shakes, push the forks down on the clamps, bringing them in line with the cap to loosen the head angle and get rid of the shake.
SHOWA SHOCK ADJUSTMENTS
We ran the race at the recommended 100mm. Overall, the stock settings are in the ballpark for most riders. For hardcore racing, these areMXARecommended 2021 CRF250 shock settings (stock settings are in parentheses):
Spring rate:52 N/mm
Race slope: 100 mm
High compression:3 turns out
Lo-compression:9 clicks out (11 clicks out)
Rebound:8 clicks out
Notes:The shock is consistent. He's not doing anything out of the ordinary. The bike does its best cornering at 100mm of incline. If you want more stability at speed, drop down to 105mm, but you'll give up supreme cornering response.
MXA FIRST RIDE: 2021 HONDA CRF250
The top speed of CRF250R is about 60-70 mph.
The CRF250R top speed is about 10-20 mph slower than the CRF450R top speed, and 10-15 mph slower than the YZ250 top speed. That said, there are a few things that have a big impact on this CRF250R top speed number.
Top speed. You can reach a top speed of about 80 mph on a CRF250L, but it's the cruising highway speed that's more important. You don't want the engine to rev at a constant high RPM if you're riding long distances on the highway.What is the difference between 2021 and 2022 CRF250R? ›
The 2021 model was an all-out revving machine that needed to be run high in the RPMs to make power. Now, the 2022 CRF250 has more bottom end power, while sacrificing some of it's top end speed. The final horsepower number is actually . 7 less on the new 250, but it feels faster because the new engine is easier to use.What is the fastest 250cc dirt bike? ›
The fastest 250cc dirt bikes are the Kawasaki XK 250 and the Yamaha WR250F, both have a top acceleration of 85 mph and similar features. The most powerful 450cc bike is the KTM 450 SX-F with a speed of 123 mph.How many miles per gallon does a Honda crf250 rally get? ›

Honda CRF250L is a powerful yet strict off-road quarter liter motorcycle, producing a max of 23 BHP and 22 Nm of torque from its 250cc, liquid cooled engine. It allows a ground clearance of 255 mm, making it suitable for all kinds of terrain available in India.
|Engine Size||Seat Height||Bike Weight|
|110cc||17″ to 25″||90lbs to 150lbs|
|125cc||25″ to 31″||130lbs to 200lbs|
|250cc||30″ to 38″||200lbs to 280lbs|
|450cc||35″ to 38″||250lbs+|
So, if you're around 200 lbs, you're probably better off picking a 2-stroke bike that has a 210 to 250cc. As a rule of thumb, 4 strokes are a little more than half the power of a 2 stroke, so if you are around 200 pounds, you will want a 4 stroke bike that is 400cc.How many gears does a crf250 have? ›
