• Importance: ♥♥ (A product of evolution rather than revolution, the KX didn't break new ground but consistently refined existing concepts.)

4. 1981 Suzuki RM125

The 1981 Suzuki RM125 was a truly futuristic machine that astonished the motocross world upon its arrival. While liquid-cooling had appeared on factory bikes previously, Suzuki perfected its application, resulting in a lighter, faster, and, crucially, far better-suspended bike thanks to its innovative Full-Floater rear shock. As was common in this era of rapid technological advancement, the RM’s period of unparalleled dominance was brief. By the following year, Honda, Yamaha, and Kawasaki had developed their own competitive models. Notably, the 1982 Suzuki RM250, a virtual clone of the ’81 125, achieved similar class-leading status.

• Dominance: ♥♥♥♥♥ (In 1981, nothing surpassed it, particularly in suspension performance.)
• Longevity: ♥♥ (Its reign was short-lived, typical for bikes of this rapidly evolving period.)
• Reliability: ♥♥♥♥ (Suzuki swiftly addressed the few issues that arose.)
• Importance: ♥♥♥ (Suzuki’s advancements spurred other manufacturers to significantly improve their suspension technology.)

3. 1981 Maico 490 Mega 2

Maico consistently demonstrated foresight in the early days of motocross, notably pioneering long-travel suspension as early as 1974. However, the pinnacle for the German manufacturer was undoubtedly the 1981 Maico 490 Mega 2. It boasted unparalleled handling for its time, complemented by a truly perfect engine. Ironically, the 490 may have inadvertently contributed to the demise of the Open class. Honda and Yamaha responded by producing more powerful engines, but they never quite replicated Maico’s exceptional power delivery. In 1982, the 490cc engine was integrated into an overweight single-shock frame, and its magic was lost. Despite Maico’s subsequent disappearance, the ’81 490 remained the class benchmark well into the mid-1980s.

• Dominance: ♥♥♥♥♥ (The best Open two-stroke of its day, with an engine considered the finest ever.)
• Longevity: ♥♥♥ (Though only one year was truly exceptional, its inherent quality ensured it remained competitive for an unusually long time for the era.)
• Reliability: ♥♥♥♥ (Dedicated Maico owners understood how to keep it running optimally.)
• Importance: ♥♥♥ (Its peak coincided with the beginning of the end for the 500cc class and Maico itself.)

2. 1974 Honda CR125M

The 1974 Honda CR125M earns its prominent position on this list through sheer volume and impact. Produced in staggering quantities, this bike single-handedly ignited the motocross boom in America. It was fast, remarkably reliable for its time, and affordably priced. This diminutive Honda heralded the decline of smaller companies like Hodaka and Penton, while simultaneously energising an entire generation of riders. Its arrival, coinciding with similar 125cc offerings from Suzuki, Yamaha, Can-Am, and Kawasaki, sparked the fierce competition that defined the 125cc class. Unfortunately, the CR125M also marked the dawn of a technology race for which Honda was initially unprepared; within a single year, the CR125M was considered obsolete by rapidly advancing designs.

• Dominance: ♥♥♥♥♥ (Even if not inherently the "best" 125, its overwhelming prevalence meant it won countless races.)
• Longevity: ♥ (By 1975, Suzuki and Yamaha offered superior bikes, and the CR saw no significant changes.)
• Reliability: ♥♥♥♥♥ (While transmissions were a known weak point, it was vastly more reliable than earlier 125cc models.)
• Importance: ♥♥♥♥♥ (Motocross as we know it today would not exist without the transformative impact of the Honda CR125M.)

1. 2008 Honda CRF450R

For many riders today, the 2008 Honda CRF450R represents the pinnacle of motocross bike engineering, not just for Honda, but perhaps for any manufacturer. It was the final Honda 450cc model to utilise a carburettor, with the subsequent 2009 fuel-injected model widely seen as a step backwards. The 2007 model, which was very similar to the ’08, was produced in greater numbers than any other dirt bike in Honda's recent history. While debates about whether current 450s are superior continue, the 2008 version's undeniable superiority to its contemporaries and its lasting presence on tracks today underscore its legendary status. It delivered a near-perfect balance of power, handling, and user-friendliness.

• Dominance: ♥♥♥♥♥ (The best 450 in 2008, and arguably still one of the best today.)
• Longevity: ♥♥♥♥♥ (Any Honda CRF450R from 2003 to 2008 is still a very good bike. In that period, each year was better than the last.)
• Reliability: ♥♥♥♥♥ (Intriguingly, the ’08 model is often considered more reliable than current Honda 450s.)
• Importance: ♥♥♥♥ (The 2007 model's unprecedented production volume made it the most ubiquitous motocross bike of the 21st century, a testament to its widespread appeal and performance.)

Here's a summary of the "Greatest MX Bikes of All Time" and their panel ratings:

The Modern Battlefield: 2025 250cc Motocross Bike Comparison

Stepping into the present, the competition in the 250cc four-stroke class is fiercer than ever. Unlike casual online opinions, our comprehensive evaluation comes from a seasoned wrecking crew with decades of experience, employing a rigorous testing methodology. We utilise a diverse range of trusted test riders, from AMA National Pros to Vets and Novices, filtering opinions through personal biases. Crucially, we live with these test bikes, racing them weekly for a full year, ensuring our rankings account for long-term durability as much as immediate track performance. For 2025, the class sees fierce competition with the introduction of Triumph alongside the established Japanese and Austrian brands.

All bikes were tested in their stock form with identical Maxxis MX-IH intermediate hard-terrain tyres, and dyno tests were conducted on the same day at Pro Circuit's race shop to eliminate variables like temperature and humidity. Every bike was thoroughly broken in before testing.

8. 2025 Suzuki RM-Z250

The Suzuki RM-Z250, despite its perennial last-place ranking, holds a unique appeal. It's built with exceptional durability, handles corners with remarkable agility, and offers a user-friendly low-to-mid powerband that novice riders particularly appreciate. It requires minimal clutch work to get moving, picking up power immediately. Suzuki celebrates 50 years of RMs by offering various Throttle Syndicate graphics and, for a limited time, includes a complete Pro Circuit T-6 exhaust system, which significantly boosts low-end power and reduces weight.

• Why it should win: Durable, nimble cornering, respectable low-to-mid power, attractive price, and enticing "RM Army Edition" package including a Pro Circuit exhaust.
• Why it should lose: Severely hindered by super-stiff Kayaba spring forks and a rigid aluminium frame. On rough tracks, it’s a handful. Low horsepower numbers are a major drawback, as it struggles to keep up with competitors even with engine modifications. It doesn't perform well when revved out, requiring short-shifting, which can cause the chassis to bind and deflect. Lacks electric start.
• Overall: The RM-Z250 remains the slowest, heaviest, and stiffest in the class. However, with suspension re-valving, its durability and cornering prowess become more apparent, and its low price point is a strong selling point.

7. 2025 Triumph TF250-X

As a first-year model, the Triumph TF250-X is remarkably polished, far surpassing many other manufacturers' initial offerings. Triumph intelligently drew inspiration from established brands, assembling a talented team of engineers and test riders. Its engine is strong, snappy, and exciting, delivering respectable, linear power on the track. Weighing in as the lightest bike at 221 pounds, it feels incredibly light and nimble. Ergonomically, the cockpit is reminiscent of previous-generation KTMs, offering excellent knee grip. Triumph didn't skimp on premium components, including D.I.D rims, Brembo brakes, a Brembo hydraulic clutch, and ProTaper handlebars.

• Why it should win: Impressively refined for a first-year model, strong and snappy engine, lightest in class, excellent ergonomics, and high-quality components.
• Why it should lose: Significant issues include notchy shifting (partially remedied by a Yamaha shift lever), faulty ECU mapping causing bogging and stalling (even after re-mapping and trying a 2025 model), a frustrating abundance of button-head Torx bolts, and the use of narrower 100/90-19 rear tyres (for weight saving, not performance). The footpegs also pack with mud easily.
• Overall: The TF250-X shows immense promise with its quality and performance. However, its notable shifting and mapping issues, combined with its newness in the aftermarket tuner scene, prevent it from ranking higher despite its potential.

6. 2025 Kawasaki KX250

The 2025 Kawasaki KX250 shows significant effort from the manufacturer to address previous complaints. Last year’s model boasted strong top-end power, and for 2025, Kawasaki aimed to improve the low-to-mid range with a new cylinder head, piston, and more efficient intake/exhaust ports. Crucially, they switched from ultra-stiff Kayaba forks to plusher Showa suspension and adopted a version of the KX450 frame. These changes result in forks that actually compress over bumps and a vastly improved turn-in, making the bike more manageable and comfortable on corner entry.

• Why it should win: Strong engine (especially top-end), improved chassis with new Showa suspension, better turn-in, and sleeker bodywork. Kawasaki's Team Green contingency program is also a significant draw for racers.
• Why it should lose: Despite engine updates, the 2025 model saw a step backward in overall power delivery, with a smaller power window requiring aggressive clutch work. The engine feels choked up, negatively affecting chassis performance, and the forks can still smash into bumps. It vibrates more than other bikes, and the ECU mapping needs refinement. The rear brake is excessively touchy.
• Overall: While the chassis is an improvement over the 2024 model, the engine's diminished performance prevents the KX250 from climbing higher. It's a trade-off where improved handling comes at the cost of the engine's previous strength, making it harder to find the power pocket.

5. 2025 Honda CRF250

The Honda CRF250, while not the strongest in terms of raw engine power, shines brightly in its chassis and handling. Our test riders consistently praised its exceptional nimbleness and ease of turning, making it a joy for whips. The Showa suspension is well-balanced and effectively absorbs large impacts. Honda’s focus on chassis refinement, driven by feedback from top riders, has resulted in a frame built from 70% new components, enhancing handling characteristics and ensuring the bike feels more planted on the track.

• Why it should win: Outstanding chassis and handling, incredibly nimble, balanced Showa suspension, and excellent ergonomics. It's also one of the most affordable bikes in its class.
• Why it should lose: The engine, despite updates to the airbox, exhaust, crank, and ECU, remains comparatively mellow and struggles to keep pace with the powerhouses from Yamaha and the Austrian brands. This lack of straight-line drive is a significant racing disadvantage. The cable clutch and raspy muffler are also minor points of contention.
• Overall: The 2025 CRF250 represents a two-step improvement over its predecessor, primarily in handling. While its stock engine is a drawback for competitive racing, the potential for significant performance gains with aftermarket modifications (as seen in the Works Edition) makes it an attractive option for those willing to invest further.

4. 2025 Yamaha YZ250F

The Yamaha YZ250F is renowned for having one of the most exciting engines in the class, thanks in part to the success of the Star Racing Yamaha team. It boasts a loud, torquey power delivery, making riders feel fast on the track, even though the rev limiter kicks in quickly. It's considered to have the second-best engine in the 2025 shootout, behind only the shared Austrian powerplant. For 2025, it features a new rising-rate linkage and updated suspension settings to improve hold-up and stabilise handling, preventing front-end dive and giving it a more "racy" feel. Yamaha's free Power Tuner app offers extensive customisation for engine characteristics.

• Why it should win: Exciting and torquey engine (especially mid-range), excellent Kayaba SSS suspension, new chassis improvements for better handling, and a highly customisable engine via the Power Tuner app.
• Why it should lose: The updated intake system, while aiming for top-end gains, unfortunately diminished the legendary low-to-mid power and increased engine braking. The engine revs out too quickly, requiring frequent shifting. The stock seat is notably uncomfortable, and the cable clutch is less preferred than hydraulic options.
• Overall: While the YZ250F remains a formidable force with its strong mid-range and superb suspension, the compromised low-end power and the need for constant shifting hold it back. It's a bike that demands aggressive riding to unlock its full potential, and its comfort could be improved.

3. 2025 GasGas MC250F

The 2025 GasGas MC250F, sharing its core platform with KTM and Husqvarna, offers many of their class-leading advantages at a more accessible price point. As one of only two completely new bikes for 2024 (alongside the YZ250F), it gained a new engine, frame, subframe, swingarm, plastics, and electronics for the 2025 model year. It benefits from the class-leading chromoly steel frame, a potent high-rpm engine, and a high-quality hydraulic clutch. GasGas distinguishes itself with slightly softer suspension valving, aiming for a more user-friendly feel than its orange and white siblings.

• Why it should win: Shares class-leading engine and frame with KTM/Husqvarna, more affordable price, durable clutch, and softer, more compliant suspension settings making it comfortable for a wider range of riders.
• Why it should lose: Intentionally detuned by its parent company: lacks a map switch (requiring an aftermarket purchase), has Braktec brakes and clutch (inferior to Brembo), forged aluminium triple clamps (not CNC-machined), a more restrictive airbox, and an internal muffler restrictor. These compromises result in less aggressive power and a mushier brake feel compared to KTM/Husqvarna.
• Overall: The GasGas MC250F is an impressive machine, offering a plush ride and usable power. While deliberately softened to differentiate it from KTM, it retains significant potential and is a strong contender, especially for riders prioritising comfort and value, with room for simple aftermarket upgrades to boost performance.

2. 2025 Husqvarna FC250

The Husqvarna FC250 stands as the "shorter" sibling within the Austrian trio, sharing the same robust foundation as KTM and GasGas but featuring a 1-inch lower seat height due to its 10mm shorter forks, shortened shock, and revised linkage arms. This design choice significantly lowers the centre of gravity, enhancing cornering abilities and making it particularly appealing for shorter riders, vets, and those new to the 250cc class. Its engine, identical to the KTM 250SXF, is powerful and linear, revving endlessly. The FC250 offers exceptional traction and confidence-inspiring stability, aided by its precise Brembo brakes and ProTaper handlebars.

• Why it should win: Lowered seat height and centre of gravity for improved cornering and accessibility, powerful and linear engine (shared with KTM), durable Brembo clutch and brakes, and refined chromoly steel frame with better flex characteristics for 2025.
• Why it should lose: The primary consistent complaint across all Austrian bikes is the spokes loosening during the engine break-in period, requiring vigilant tightening. While minor, it's a regular maintenance point. Some faster riders might prefer the full suspension travel of the KTM.
• Overall: The Husky FC250 is an outstanding machine, especially tailored for its target audience. Its combination of a powerful engine, confidence-inspiring handling, and unique lowered chassis makes it incredibly user-friendly and competitive, narrowly missing the top spot due to its slight airbox restrictiveness compared to the KTM.

1. 2025 KTM 250SXF

For the third consecutive year, the KTM 250SXF proudly claims the "MXA 250 Bike of the Year" award. Its engine is the undeniable class winner, sharing its prowess only with its Husqvarna and GasGas brethren. While the Yamaha YZ250F offers a stronger low-to-mid punch, the KTM’s power window is broader and more sustained, pulling relentlessly through the rev range. The hydraulic Brembo clutch is the most durable in the class, a fact underscored by its widespread use by factory teams in AMA Supercross and Nationals. The KTM’s subframe design, with its open area beneath the seat, maximises airflow to the intake, delivering a more exciting throttle response than its stablemates. It also features more aggressive, race-oriented suspension settings that suit the widest range of riders.

• Why it should win: Class-leading engine with broad, sustained power delivery, most durable hydraulic Brembo clutch, superior Brembo brakes, open subframe design for optimal airflow and throttle response, race-oriented and confidence-inspiring WP suspension, and a highly user-friendly setup.
• Why it should lose: It has gained some weight since 2022 (though slightly reduced for 2025). The spokes still tend to loosen during break-in, and the frame requires several hours to fully break in. The WP XACT air forks, while capable, demand regular air pressure checks, especially in warmer conditions, which can be a minor inconvenience for some riders.
• Overall: The KTM 250SXF stands as the benchmark in the 250cc class, delivering an unparalleled combination of power, handling, reliability, and ease of use. Its ability to effortlessly handle rough terrain, outpace competitors on straights, and carve through corners with precision makes it the undisputed champion.

Here’s a comparison of the 2025 250cc motocross bikes based on key performance metrics:

250cc Four-Strokes vs. 450cc Motocross Bikes: Which Is Best?

The perennial debate in motocross often boils down to the choice between a 250cc four-stroke and a 450cc four-stroke. With over 50 years of experience, Motocross Action has observed this evolution firsthand. While social media is rife with unqualified opinions, our long-term testing and diverse rider feedback provide a nuanced perspective.

In the 450cc class, pure horsepower is often less critical, as most riders rarely exploit the full potential of such a powerful engine. Instead, handling becomes a greater priority, as managing a higher-speed machine demands more control. Conversely, in the 250cc class, the engine’s performance is paramount for competitiveness. The lighter overall weight, reduced rotating mass, and slower engine speeds typically make the chassis easier to dial in.

The 250cc four-strokes, like the KTM 250SXF, thrive when ridden at high RPMs, demanding riders to be precise with their shifting and maintain momentum. They offer a lively, agile ride that can be incredibly rewarding. The 450cc machines, however, deliver immense torque and brute power from lower in the rev range. This makes them less reliant on constant high-revving but demands a different kind of skill: managing the explosive power and preventing arm pump. For many, a 250cc offers a more engaging and physically less demanding ride over a full moto, allowing riders to push harder for longer. Ultimately, the "best" choice depends on a rider's skill level, riding style, and local track conditions. Pros might prefer the raw power of a 450, but for many amateur and veteran riders, the manageable yet potent nature of a 250cc four-stroke makes it the superior choice for consistent performance and enjoyment.

The Horizon: Will We See a 250RX Motocross Bike?

The motocross market is constantly evolving, with new manufacturers entering the fray and established brands refining their offerings. While our testing crew rigorously evaluates every new machine, the question of future models, particularly a 250RX motocross bike, often arises.

Currently, Italian manufacturer Beta has made its entry into the motocross market with a 450RX model. However, as they do not yet produce a 250cc four-stroke enduro bike, a 250RX motocross model is not anticipated in the near future. Similarly, Ducati is actively working on a significant entry into the motocross world, with their Desmo450 MX expected by 2026. A timeline for a 250cc four-stroke from Ducati, however, remains unconfirmed. Triumph has already made a notable splash with their TF250-X, demonstrating that new entrants can bring innovative and competitive machines to the class, despite initial teething issues.

It's a common misconception that "all bikes are the same," suggesting one should simply choose a colour preference. This couldn't be further from the truth. While aftermarket modifications can elevate a lower-ranked bike, applying similar enhancements to a top-tier machine will only widen the performance gap further. Our rankings focus on stock models, excluding limited-edition "Works Edition" or "Factory Edition" bikes with their significant price premiums, as these do not represent the standard consumer offering.

Frequently Asked Questions (FAQs)

What makes a motocross bike "great" beyond just speed?

Beyond raw speed, greatness is determined by dominance over its competitors, longevity in remaining competitive without major changes, reliability in harsh conditions, and its overall importance in shaping the sport or influencing future designs. A bike's impact on rider accessibility and popularity also plays a crucial role.

Why do some bikes consistently rank lower in modern shootouts?

Bikes that consistently rank lower often suffer from a combination of outdated technology (e.g., lack of electric start), compromised suspension settings that are too stiff for most riders, and engines that produce significantly less horsepower than the competition. While they might excel in specific areas like cornering or durability, these drawbacks limit their overall competitiveness in a modern racing environment.

Are air forks better than coil-spring forks on motocross bikes?

Both air forks (like WP XACT) and coil-spring forks (like Kayaba SSS or Showa) have their advantages. Air forks are lighter and highly adjustable via air pressure, allowing for quick changes to suit different track conditions or rider weights. However, they require regular pressure checks. Coil-spring forks are often praised for their consistent feel and plushness, requiring less frequent adjustment, but they are heavier and less tunable without internal modifications.
