It would be best to look at many things when choosing a dirt bike. One of these things is the bike’s power. In most cases, it is typically signified as “cc.” You will find a number, and then next to it is the representation “cc.” It is these letter and number mixtures that specify the bike’s power. In the world of dirt bikes, 250cc bikes are known to be one of the best machines. If you decide to go with the 250cc machines, you will still have one tricky task.
Fastest 2 Stroke Dirt Bikes
1. Honda CRF 250R
With the new DOHC engine and a new framework, Honda has made the CRF 250R proficient in leading the 250cc class. This promoted model bears an absolute novelty in weight and handling, courtesy of the HRC team! Owing to its stripper bars and a reviewed profile, Honda has saved more than a kilogram in weight. Moving on to the suspension, nothing is absent from the 49 mm USD fork from Showa, which parenthetically is derived from the HRC GP riders’ factory model. Thanks to a reformed triple clamp and an extra 5 mm of suspension travel, this 250R offers near-perfect handling!
Of course, Honda has been providing the riders of CRF250R with electronic assistance for quite some time now. You will find ECU with unique engine charting for each gear, even in the new type. This mapping permits you to deliver ideal power as per your choice for each gear. There is also an electric starter on board as standard and the tried-and-tested HRC Launch Control.
With a capacity of 250cc, the engine has been totally repaired from the cylinder head to the transmission, thus resilient an increase in power output of 10% and likewise, an increase of around 15% in torque output. The thermal system is made more effective by new heaters, while the clutch now has nine discs and the transmission, which is calmer to change, features enhanced gear ratios.
A more efficiently intended seat and new plastic parts upsurge freedom of movement. At the same time, a new single muffler swaps the twin mufflers on the new CRF 250R. One can certainly feel this surge in output and the difference in ergonomics from its forerunners. This difference makes the CRF250R the most powerful 4-stroke dirt bike in the 250cc class, in our opinion.
2. Yamaha YZ 250F
An all-new engine with an electric appetizer and lithium-ion battery, new cylinder head, new flat bogus piston, better camshaft design, larger clutch, and much more have been presented on the latest YZ 250F model from Yamaha. Though the engine remains in its backward-inclined design, the angle of disposition has been abridged. At the same time, some lighter gears are added to the accelerator body, while the fuel injector has also been adapted. The bottom line is that the new Yamaha YZ 250 F will thus offer even more power in the mid and upper power ranges and a better center of enormity.
As for the reshaped airbox, its consumption funnel has been detached, and its length has been reduced by 20 mm to create a more direct path for the arriving air. One other significant change is using a new air filter housing cover that is mounted on the front of the seat. This new cover upsurges air intake volume using reshaped intake channels to send even sturdier performance at high RPMs.
Added to all these promoted features is the advanced Yamaha power tuner app. This easy-to-use digital app lets riders correct the dynamics of their bike’s engine to suit the course and prevailing weather conditions simply with the help of their smartphones. It is obtainable as a free app for iOS or Android devices and can be downloaded from the app store. Post which, riders can connect to the YZ250F via the bike’s Wi-Fi border. Twists to fuel injection and explosion timing can also be made via the bike’s devoted CCU (Communication Control Unit). Furthermore, riders can also generate and save their settings using the app.
3. KTM 250 SX-F
With power and presentation like no other, the KTM 250 SX-F is one of the best dirt bikes in its class. With its solid design, excellent mass domination and really low weight of just 98 kilograms, the new KTM 250 SX-F is the complete powerhouse in the 250 cm³ 4-stroke class. And while the performance features are very outstanding, it is still easy to ride for both beginners as well as expert riders. Designed to deliver the uppermost and most robust excellence, the KTM 250 SX-F’s chassis is made-up of robot-welded hydroformed steel tubular and treated with a heavy-duty dust coat. This certifies that the frame replies well to the lively riding patterns in dirt bike riding.
At the same time, the seating idea is planned to combine dynamism and comfort. In addition, the latest form is adorned in different colours based on the KTM factory production models. Speaking about the engine, it is driven by a 249.9 cm³ single-cylinder 4-stroke engine, which, by the way, weighs just 25.9 kilograms and is proficient in making a maximum power output of 41.1 HP @ 13,700 RPM and a maximum torque of 25 NM @ 9,100 RPM.
As a tribute to KTM’s eminent heritage in the motocross world, the KTM SX range has been given a misty remodeling, combining the typical Red Bull KTM Factory Racing colours with an old-school inspired design. A brand-new blue seat and orange frame complete this appealingly inspiring package.
4. Husqvarna FC 250
There are a lot of riders who will give Husqvarna a pass as they feel that it is just a white KTM. While there are fundamentals of truth to this, there are noteworthy changes as well. First of all, there are gears that Husqvarna uses, for example, high-quality rims from Japanese D.I.D, ProTaper handlebars, and a combined subframe that makes it easy to use. The advanced model comes with a lower suspension, making it reasonably simple for less skilled riders who have just arrived in the world of dirt biking. Experienced riders also love this lowered seat height since it gets much cooler to a corner and performs a variety of maneuvers.
Seemingly, the engineers at Husqvarna chose their path while scheming the chassis. With its high front and low rear, this setup, mainly prevalent in the U.S., has also been accepted in the regular series of Huskies. This setup’s essential rewards comprise; excellent grip and smooth steering constancy, something that the blue and white crossers also benefit from on the very rough dirt track.
The FC 250 thrusts smoothly and precisely through the corners and remains steady on its course, even on sharp ridges. Yet, there is one disadvantage to this American styled dirt bike; these Huskies are not as nimble on challenging and slippery trails as their orange siblings. But that is by no means as bad as it sounds. By growing the rear spring preload and pushing the fork legs further into the triple clamps, you can reinstate the unique cross bike feel!
5. Suzuki RM-Z250
While the history of the Suzuki RM-Z 250 began in 2004, a studied model containing Suzuki’s first electronic fuel injection on a four-stroke 250cc motocross machine was first introduced in 2010, and the Suzuki Holeshot Assist Control (SHAC) was later introduced in 2016. The engine and its frame also received renovations during this period. But, the latest RM-Z 250, which features a 249cc 4-stroke single cylinder DOHC engine, has been entirely reshaped. Running in at low-to-medium power series, the Suzuki RM-Z250 is one of the coolest dirt bikes to ride. It maxes out well under 8,000 RPM, so there’s no point in getting it past its peak of 11,600 RPM.
In fact, its power is voluntarily accessible at low RPMs while still being sensibly smooth till 8,000 RPM. This relaxed nature makes it perfect for younger riders who are not ready for the fiery 14,000 RPMs of KTM’s SX-F 250 or the Husqvarna’s FC 250.
Including a lightweight framework, better mount, promoted forks and shocks, and a reformed handlebar, the new RM-Z 250 is even more receptive than its prior model. As for the frame, a change has been made to a polygonal tubular profile. The new swipe arm is no longer made using a drop faking process, but a hydroforming process, removing any fused layers. In addition, the placement of the engine has been tuned to be closer to the centre of the chassis. Indeed, all these small details are not directly apparent to a rider, but they make the RM-Z250 more lithe and easy-to-ride dirt bike.
