Across 5 covered model years from 1990 to 2006, the Kawasaki KX 125 motorcycle has supplied dry weights ranging from 190.7 lb (86.5 kg) to 192 lb (87.1 kg).
Kawasaki KX 125 weight overview
This is a genuinely light bike. That usually makes parking, pushing it around a garage and catching small low-speed balance errors easier than on larger motorcycles. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

What the weight numbers tell you
Kawasaki KX 125 weight FAQ
How much does the Kawasaki KX 125 weigh?
The source data gives 190.7 lb (86.5 kg) to 192 lb (87.1 kg) as dry weight. A fueled, road-ready bike will weigh more than this figure.
Are all Kawasaki KX 125 model years the same weight?
There are year-to-year differences in the supplied data. The earliest covered year is used as the baseline, with later changed values shown separately above.
What does a full tank of gas weigh on the Kawasaki KX 125?
A full tank works out to about 13.5 lb (6.1 kg) to 14 lb (6.3 kg) from the listed 2.17 US gal (8.2 L) to 2.25 US gal (8.5 L) capacity. Actual fuel density varies slightly, so treat it as a practical estimate.
What does the Kawasaki KX 125 weigh with a 180 lb rider?
The approximate combined total is 371.8 lb (168.6 kg) with a 180 lb rider, based on the representative dry weight used on this page.
Is the Kawasaki KX 125 strong for its weight?
The calculated range is 20.7 hp per 100 lb. This ratio is usually more informative for acceleration comparisons than horsepower alone.
How much heavier will the Kawasaki KX 125 be than its dry weight?
Do not treat dry weight as curb weight. Adding the listed fuel capacity alone produces roughly 204.7 lb (92.8 kg) to 205.7 lb (93.3 kg); the true ready-to-ride figure can still differ because dry-weight definitions vary.
How much of the Kawasaki KX 125 total weight comes from fuel?
Fuel accounts for roughly 7% to 7.3% of the available motorcycle weight figure. On lighter bikes that share can be surprisingly noticeable.
How does Kawasaki KX 125 torque compare with its weight?
Available data gives 9.48 lb-ft per 100 lb to 10.19 lb-ft per 100 lb. That ratio helps explain how strong the engine is relative to the bike’s mass, especially at lower speeds.
What is the Kawasaki KX 125 engine-size-to-weight ratio?
The model has about 0.65 cc per lb in the available data. This simply shows how much engine displacement there is for each pound of motorcycle weight.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications. Confirm critical figures in the owner’s manual or on the official Kawasaki website.
