Kawasaki has officially announced its 2027 KX motocross line-up, including the confirmation of the newly-introduced KX327 two-stroke alongside updated KX450F and KX250F four-stroke models.

The 2027 Kawasaki KX327’s chassis is derived from its flagship KX450F, with a completely new purpose-built fuel-injected, single-cylinder engine.

Marking Kawasaki’s first new two-stroke model over 250cc in more than two decades, the 327cc engine delivers a new level of controllability and performance. Its flat torque curve and precise fuel injection ensure smooth, predictable power delivery from ultra-low to mid rpm, allowing riders to maintain traction and momentum through technical sections without hesitation.

The engine provides consistent performance in any environment, while its inherently lightweight two-stroke design helps achieve a total weight comparable to a 250 class four-stroke. Staying true to its roots, the use of pre-mix lubrication adds a simple, nostalgic element that enhances the overall riding experience.

Supporting the engine is a chassis built around Kawasaki’s aluminum perimeter frame, delivering the balanced handling and stability riders expect from the KX family. High-performance suspension components provide excellent front-end feedback, precise cornering, and composure at speed, while aggressive Lime Green bodywork and slim, rider-focused ergonomics reinforce the bike’s race-ready intent.

The result is a new generation of KX – lean, athletic, and built to perform – due for release in late 2026 at the MSRP of $9099 in the United States market.

In addition, the 2027 Kawasaki KX450F – reintroducing the ‘F’ to the model name to signal its flagship presence among the KX model line – boasts a more refined and race-focused package.

Updates to the intake and exhaust systems give the KX450F a stronger, more responsive feel when the throttle is opened, with improved low-end pull and stronger performance through the mid- to high-rpm range.

A redesigned chassis, including a revised swingarm, improves rear-wheel traction and control, while a longer wheelbase adds stability at speed, helping riders stay planted in demanding conditions. Premium components, including a full Brembo braking system, further enhance performance and control on the track.

The updated bodywork features a slimmer, more compact design with smooth surfaces, complete with Kawasaki’s signature Lime Green styling. It also has improved smartphone connectivity, offering more intuitive engine tuning, expanded launch and traction control adjustability, ride logging, monitoring functions, and maintenance reminders.

Overall, the 2027 KX450F is more stable, and more capable than ever, continuing to deliver the performance needed to compete at the highest level.

The 2027 Kawasaki KX250F builds on the major performance gains of the 2025 model with a sharper focus on race day results. Developed using direct feedback from competitive riders, the new KX250F delivers stronger, more usable power with smooth, controllable delivery, allowing riders to push harder.

Engine updates, including refinements to the combustion chamber, revised exhaust pipe length, and an optimized silencer, contribute to stronger power across the entire rpm range. Updated FI settings provide a crisper, more linear throttle response, while a larger-capacity clutch improves power transfer to the rear wheel for stronger acceleration and better control out of corners.

The lightweight chassis retains the agile, confidence-inspiring feel introduced in the current model, now further refined for improved stability and handling. Updated front and rear suspension settings enhance traction and ground feel, helping riders stay consistent as track conditions change. The result is more confident line selection and the ability to ride more aggressively with greater confidence.

Up front, new styling elements including the number plate, front fender, and fork guards feature a slimmer, more purposeful design that reflects the KX’s race-ready character. The 2027 KX250F is built to perform when it matters most, continuing to evolve Kawasaki’s 250cc platform with the goal of developing the next generation of champions.
