2027 Kawasaki KX250F Review

Although Kawasaki completely redesigned the KX250F in 2025, it has still given it a surprising number of updates for 2027. With the KX450F all-new this year, the 250F will likely follow with a full redesign in 2028. Kawasaki could have carried over the 2026 model unchanged. Instead, it took the harder route and made several thoughtful refinements to the 2027 KX250F. We joined Team Green at Perris Raceway for a first ride.

The first thing you’ll notice is the return of the “F” designation, which identifies the bike as a four-stroke ahead of the highly anticipated KX327 two-stroke expected later this year. The KX250F’s most significant updates address the AMA’s new sound regulations, a common theme among 2027 competition models. The header is now 3.5 inches longer and feeds a larger muffler designed to help the bike meet the new 109-decibel limit. Kawasaki didn’t want the quieter exhaust to come at the expense of power, so it reshaped the combustion chamber with a more hemispherical profile and revised the EFI settings to match. The familiar handlebar-mounted mapping controls remain, though Kawasaki says the aggressive setting is now even more aggressive. Altogether, the engine is claimed to produce 0.7 horsepower more than the 2026 model.

Inside the engine, the coned-disc spring clutch receives 15 percent more spring pressure. The goal is to improve feedback at the lever and create a more direct connection between the throttle and rear wheel. Kawasaki also reshaped the clutch and brake levers for a broader, more natural feel, replacing the narrow design used in previous years.

The KX250F also gets a visible facelift with a new front fender and number plate. The shorter fender includes a mounting location for the LitPro-style GPS unit slated for the 2027 KX450F because both models share the same fender. The redesigned number plate routes the cables behind it rather than across the front.

Kawasaki also redesigned the radiator hoses, eliminating the Y-shaped junctions in favor of dedicated hoses for each side of the bike. According to Kawasaki, the change saves enough weight to offset the larger, longer exhaust. The claimed wet weight remains 240.8 pounds, keeping the KX250F one of the heavier bikes in the class.

One number did drop: the MSRP. Kawasaki lowered the price by $500 to $8599. Price reductions are rare these days, so Team Green deserves credit for making the KX250F a little easier to buy.

Returning features include Kawasaki’s Ergo-Fit system with adjustable handlebar mounts and footpegs, Showa suspension, a Nissin hydraulic clutch, dual fuel injectors, quick air-filter access, selectable power modes and Rideology KX app connectivity.

Time To Ride | 2027 Kawasaki KX250F Review

 The first thing I noticed as I swung a leg over the bike was the new levers. Their revised shape is far more comfortable and finally feels like a conventional lever. Thank you, Kawasaki. It may sound like a small detail, but it makes a meaningful difference on the track.

Kawasaki also changed the mapping controls. The standard “light off” setting is now the most aggressive option rather than light on. Holding the mode button for three seconds switches to the smoother “light on” map. I basically left the bike in the full-power light-off setting to sample everything the KX250F had to offer.

Right away, I noticed how directly the throttle connected to the rear wheel. The engine responded cleanly, and rear-wheel drive felt immediate. Some of that comes from the stronger clutch, while the longer header helps smooth the power delivery from low to mid rpm. The crisp mapping reinforces the KX250F’s clean, connected feel.

The engine does its best work from the midrange through the top end. Power builds noticeably in the middle and continues to pull toward redline, so the upper end of the rev range never makes the next shift feel urgent. Unlike KX250Fs from a few generations ago, which demanded to be ridden almost exclusively at the top, this engine is useful in the midrange while retaining its racey, high-revving character.

The KX250F is less convincing at the very bottom. It requires more clutch work and higher rpm than I prefer—or expect from a race-ready 250F—to pull cleanly out of a tight inside rut. I wanted the engine to spin up more quickly off the bottom before transitioning into its strong mid-to-top pull. I tried a more aggressive map but didn’t find a meaningful solution during our test day. A larger rear sprocket may be the answer, helping the engine respond faster when you open the throttle.

Kawasaki revised the suspension settings for 2027, and they worked well. At 190 pounds, I’m on the heavier side for a 250F, yet I never felt as though I was overwhelming the Showa components. Perris Raceway is fast and jumpy, but the KX250F took it in stride. The suspension stayed up in the stroke without diving on steep jump faces or blowing through on hard landings. It also remained predictable on corner entry and through tight ruts. Previous KX250Fs have sometimes felt unbalanced front to rear—usually with a harsh fork—but this bike never felt pitchy in either direction. My only adjustment was two clicks softer on the fork to improve front-end traction. One caveat: Although the settings worked well for me and other 190-pound vet riders, a smaller rider moving up to a 250F may find the suspension too firm.

Are the 2027 changes dramatic? No. But it’s encouraging to see Kawasaki continue developing a bike that may be completely redesigned next year. Without riding a 2026 model back-to-back, it’s difficult to quantify the improvement. Even so, the changes are worthwhile. The new levers, revised mapping, stronger clutch and updated suspension give the KX250F a polished, race-ready feel straight out of the crate.CN
