Across 5 covered model years from 2021 to 2025, the Kawasaki KLX300 SM motorcycle has supplied dry weights ranging from 302 lb (137 kg) to 304.2 lb (138 kg).
Kawasaki KLX300 SM weight overview
This is on the lighter side for a road motorcycle. The advantage is usually most obvious while parking, maneuvering at walking speed and moving the bike around off the engine. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

Kawasaki KLX300 SM weight FAQ
How much does the Kawasaki KLX300 SM weigh?
The source data gives 302 lb (137 kg) to 304.2 lb (138 kg) as dry weight. A fueled, road-ready bike will weigh more than this figure.
Are all Kawasaki KLX300 SM 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 KLX300 SM?
A full tank works out to about 12.4 lb (5.6 kg) from the listed 2 US gal (7.57 L) capacity. Actual fuel density varies slightly, so treat it as a practical estimate.
What does the Kawasaki KLX300 SM weigh with a 180 lb rider?
The approximate combined total is 484.2 lb (219.6 kg) with a 180 lb rider, based on the representative dry weight used on this page.
How much heavier will the Kawasaki KLX300 SM be than its dry weight?
Do not treat dry weight as curb weight. Adding the listed fuel capacity alone produces roughly 314.5 lb (142.6 kg) to 316.7 lb (143.6 kg); the true ready-to-ride figure can still differ because dry-weight definitions vary.
What is the estimated Kawasaki KLX300 SM weight with a full tank of gas?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 314.5 lb (142.6 kg) to 316.7 lb (143.6 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
What is the Kawasaki KLX300 SM displacement per pound?
The model has about 0.96 cc per lb in the available data. This simply shows how much engine displacement there is for each pound of motorcycle weight.
Is the Kawasaki KLX300 SM easy to move around by hand?
The number is manageable for a road bike, but you still notice it when parking, making tight low-speed turns or catching a lean. On the move, chassis balance can make it feel lighter than the scale suggests.
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.
