Overview
The Kawasaki KX 100 is a motocross bike in the KX family, produced from 2005 through 2022. The 2022 model has a 99.0 cm³ liquid-cooled, single-cylinder two-stroke engine, a six-speed manual gearbox, and a wet weight of 77.0 kg; power and torque figures are not included here.
At 871 mm, the seat is high enough that shorter riders may have trouble getting both feet down. The 77.0 kg wet weight makes the bike easier to maneuver at low speeds, while 330 mm of ground clearance and 274 mm of travel at each wheel suit uneven terrain; the fork offers compression damping adjustment, and the rear shock adds compression, rebound, and spring-preload adjustment. It has kick starting and premix lubrication, so starting is by kick and the oil must be mixed with the fuel; the tank holds 5.00 liters.

Pros and cons
Advantages
Light wet weight
At 77.0 kg wet, the KX 100 is easier to maneuver at low speeds than a heavier motorcycle.
Adjustable suspension
Compression damping can be tuned at both ends, with rebound damping and spring preload also adjustable at the rear.
Ground clearance
The 330 mm clearance helps the bike pass over uneven motocross terrain.
Things to consider
Kick-only starting
There is no electric starter, so starting always requires using the kick lever.
Premix lubrication
The oil must be mixed with the fuel rather than added through a separate oil tank.
Small fuel tank
The 5.00-liter tank carries a limited amount of fuel between stops.

How to measure
Stand barefoot with your back to a wall. Hold a book firmly between your legs, then measure from the floor to the top edge of the book.
Estimated ground reach
Tiptoes likely; one-foot stops may feel easier
Plan to use a one-foot stop and test the motorcycle before buying.
