2020 Kawasaki KX250 Review – The latest generation of the Kawasaki KX250 was introduced in 2017. The year after Kawasaki made several changes to the engine to bring back some of the hits in the Power band the previous generation bike had. The engineers made some internal settings changes to the Showa suspension components in 2018 as well. The bike improved, but it still lacked top-end power compared to the competition and the fork felt harsh in the initial part of the stroke.
2020 Kawasaki KX250 Review
The 2019 model was identical to the 2018 bike, except for the color change on the lower part of radiator fire sparks and the “F” dropped from its name. For 2020, Kawasaki has given the engine a lot of updates in an effort to increase high-RPM power and has spec ‘d new KYB suspension components. So did a few minor revisions to the chassis. Kawasaki invited us to Castillo Ranch MX in Los Alamos, California, to ride the 2020 KX250, and we came away satisfied with its performance after our first day of testing.
2020 Kawasaki KX250 Engine
The engine may look the same from the outside, but significant changes lie inside – the most significant is the valves are now activated by finger adherents, more aggressive camshaft profiles, larger valves, a 1mm larger bore, 1.4mm less stroke, a 1mm larger Throttle body, a revised piston crown for increased compression, and a shorter intake funnel. Also, Kawasaki informed us the reef limit has been increased by 650 rpm over last year’s model. When kickstarting the bike, we noticed that it required a more powerful kick compared to the 2019 model, probably due to the increased compression.
The bike still kicks relatively lightly, but we noticed it took a few extra kicks to fire to life when it got hot. The engine retains the sharp power delivery and good midrange of the previous bike, but noticeably pulls harder and farther on the upper end, allowing the rider to hold a gear longer and without the need to switch excessively to keep the bike in the flesh of the Power band , as was the case with last year’s model. With the flesh of the Power band being moved higher in rpm range, we noticed the new KX250 has slightly less bottom-end power, but it’s more than a valuable trade-off for newfound high RPM traction. The green machine retains its easy clutch pull as well.

In addition to moving away from Showa separate Function Fork (SFF) and Showa Shock the 2017 to 2019 model used, Kawasaki has spec ‘d a new KYB 48mm Coil spring fork and KYB shock with higher spring rates. The fork is up from 9.4 N / mm to 10.0 N / mm and the shock has been increased from 52 N / mm to 54 N / mm. The KYB fork is a remarkable improvement over the Showa SFF unit as it gives a very plusher feel, is more progressive and has no harsh stains throughout the battle. It is a bit on the fixed side though. On our first test day, we found good results going four clicks softer on the compression, giving the fork more comfort on brake bumps but retaining good bottom resistance on jump landings. The KYB shock worked well and we left the Clickers in the stock position on our first day of testing.
2020 Kawasaki KX250 Chassis / handling
The 2020 KX250 has a lower front engine mounts that now uses a stud bolt design, a 250mm rear brake disc, a revised rear brake master cylinder and brake line, and now runs the same front brake pads as the 2019 and 2020 KX450. The chassis may be the least modified part of the KX250, but that’s not a bad thing, as it’s one of the most neutral-handling, easy-to-get-used bikes in its class. It has narrow radiator shafts and a slender center section and a side license plate area. The Renthal 971-Bend handlebar stock is high relative to the seat height; We would prefer lower mounts or a bar with less pitch. The seat is flat, which complements the slim body as it makes it easy to get back and forth.
2020 Kawasaki KX250 General Appearance
Kawasaki took feedback from the media and its consumers, and improved the KX250 in the areas that needed the most attention-engine and suspension. While it may look similar on the outside, this is a book that should not be judged by its coverage as 2020 marks the largest performance increase the latest generation KX250 has received. We hoped it would come with an electric start for MY20, but have to imagine it coming in the near future. We will spend more time testing the KX250 leading up to the 2020 250F motocross Shootout and will have a full review of the bike before then as we learn more about it, but we can safely say after our first day of riding it, that it is a noticeable improvement over its p redecessor.
