MXA Race Test: An In-Depth Look at the True Performance of the 2025 Suzuki RM-Z250 – How It Stands Up on the Track
The world of motocross is ever-evolving, with manufacturers constantly pushing the envelope to design bikes that offer better performance, handling, and overall rider experience. One of the most anticipated bikes in 2025 is the Suzuki RM-Z250, which promises to deliver a new level of performance in a fiercely competitive class. But does it live up to the hype? The Motorcycle X-Press Association (MXA) took on the task of thoroughly testing the 2025 Suzuki RM-Z250, pushing it through rigorous race scenarios, evaluating its strengths and weaknesses, and giving a detailed, hands-on review that covers everything from its engine performance to its handling and suspension.
The Evolution of the Suzuki RM-Z250
The Suzuki RM-Z250 has a long-standing legacy in the motocross world, known for its competitive edge and consistent performance. However, as with all vehicles in this high-demand segment, Suzuki has to keep pace with rivals like Honda, Yamaha, Kawasaki, and KTM, all of whom continuously raise the bar. The RM-Z250 was redesigned with several key updates for 2025, many of which reflect Suzuki’s intent to regain its competitive edge.
The 2025 model arrives with noticeable changes, particularly in the engine, chassis, and suspension systems, designed to improve throttle response, handling, and overall race-day performance. MXA’s race test dives into each of these areas, evaluating how well the bike performs under competitive conditions.
Engine Performance: Smooth Power with Room for Improvement
The heart of any motocross bike lies in its engine. Suzuki has gone to great lengths to refine the 249cc, liquid-cooled, four-stroke engine in the RM-Z250. For 2025, Suzuki has made incremental improvements to the power delivery, including adjustments to the fuel injection system and the addition of a new exhaust system designed to increase low-end torque and mid-range power.
When MXA took the bike out for testing, the first impression was that the 2025 RM-Z250 has a smooth, linear power delivery. The engine doesn’t hit with the brute force seen in some of its competitors, but it offers a controlled, predictable output that makes it easier for riders to handle, especially when navigating tight corners or handling technical sections of the track.
The low-end response has improved compared to previous models, making the bike more rideable in softer, lower-traction conditions, like ruts or sand. The mid-range power is where the RM-Z250 really shines, allowing riders to maintain speed through turns and surge up jumps with minimal effort. However, there is still a slight gap when compared to some of its rivals in the higher RPM range, where bikes like the Yamaha YZ250F and Honda CRF250R pull away slightly. The engine feels solid but could benefit from a bit more top-end power to match the competition in full-on acceleration.
The throttle response, aided by the Suzuki’s advanced fuel injection system, is crisp and responsive. Riders will appreciate how the engine maintains its composure even when pushed to its limits, though the upper range could still be refined for riders who crave more aggressive acceleration.
Suspension and Handling: Refining the Ride
The suspension system of any motocross bike plays a crucial role in determining how it handles the varied terrain encountered during a race. The 2025 Suzuki RM-Z250 is equipped with a Showa 49mm SFF-Air TAC fork in the front and a Showa rear shock that works together to provide a balanced, plush ride.
MXA’s test riders were particularly impressed with the RM-Z250’s handling. The chassis feels solid and stable, especially in high-speed sections and during cornering. The front end stays connected to the ground, providing a high level of control when entering turns, while the rear suspension provides the necessary support to absorb the big hits and chop typically encountered in rough terrain.
The Showa fork offers a good balance of plushness and performance, absorbing bumps well without feeling overly soft. In the rear, the shock offers excellent mid-stroke support, keeping the rear end stable during aggressive acceleration and when coming out of corners. However, like most bikes, there are trade-offs: heavier riders might find the rear suspension a bit too soft in certain situations, requiring some tuning to find the optimal setting.
The Suzuki RM-Z250 shines in its overall agility. It feels light on its feet, allowing riders to quickly change direction and react to changing track conditions. The bike feels extremely nimble and responsive in tight corners and technical sections, with the chassis working in harmony with the suspension for a confident, planted feel.
Ergonomics and Comfort: Rider-Focused Design
When it comes to motocross, comfort is crucial, especially during long motos or when pushing through tough track conditions. The 2025 RM-Z250 features updated ergonomics that improve comfort for a wide range of riders. The bike’s seat is firm but offers enough cushioning to provide a balanced ride, even during extended periods of standing or seated riding. The handlebars are positioned to offer a comfortable reach, and the overall geometry of the bike provides a natural riding stance.
MXA’s test riders noted that the Suzuki RM-Z250 offers a good amount of space for different riding styles. Whether you’re a taller rider or someone with a more compact frame, the bike’s adjustable components help ensure that most riders can find an ideal setup. The footpegs are solid and provide excellent grip, giving riders more control over their bike, especially in aggressive cornering.
Brakes: Stopping Power When You Need It
In the world of motocross, brakes are an often overlooked but incredibly important component of a bike’s overall performance. Suzuki equipped the 2025 RM-Z250 with a high-performance braking system that combines a 270mm front disc and a 240mm rear disc for optimal stopping power.
During testing, MXA found the brakes on the RM-Z250 to be highly effective. The front brake provides strong, progressive stopping power that helps riders control speed in corners or during jumps. The rear brake, though not as aggressive as the front, offers solid feedback and control, preventing any unwanted rear-wheel lockup in tricky conditions.
Both brakes offer a high level of precision, which is essential for motocross riders, especially when navigating tight sections of the track or performing quick, technical maneuvers. Overall, the braking performance of the 2025 RM-Z250 stands out as one of its stronger points.
Final Thoughts: A Solid Contender in the 250cc Class
After an extensive race test, it’s clear that the 2025 Suzuki RM-Z250 is a well-rounded machine that delivers on its promise of improved performance. The bike excels in handling, suspension, and comfort, making it an excellent choice for riders who prioritize agility and stability. Its engine is smooth and reliable, though it could benefit from more power at the top end to truly compete with the best in its class.
While it may not have the brute acceleration of some of its competitors, the RM-Z250’s balanced approach to power delivery, handling, and comfort makes it a competitive choice for motocross racers who value consistency and predictability. With the right setup, the Suzuki RM-Z250 can compete at the highest level, and it remains one of the most rider-friendly bikes in the 250cc category.
In conclusion, Suzuki has managed to craft a motocross bike that blends reliable performance with the precision and control needed for serious racing. The 2025 RM-Z250 is a solid contender in the fiercely competitive 250cc class and is sure to be a favorite among riders looking for a versatile and competitive machine. Whether you’re an amateur rider looking to step up your game or a seasoned pro aiming to fine-tune your setup, the Suzuki RM-Z250 should definitely be on your radar for the 2025 motocross season.
