Kids and mini · Four stroke

Kawasaki KLX110

The kids' trail bike and pit bike that everyone has owned or borrowed. Auto clutch, four speed, air cooled, and impossible to kill. The L version has a manual clutch for bigger riders. Sold in Australia from 2002 to 2020, 19 model years.

About the Kawasaki KLX110

The KLX110 is the bike that fills every pit and every back paddock. It is a 112cc air cooled four stroke with a four speed gearbox and an automatic clutch, electric start on the newer bikes, and a build quality that shrugs off years of neglect. The KLX110L (and later the R L) has a manual clutch and taller suspension for older kids and adults.

It suits kids from about seven to eleven, or an adult who wants a pit bike. It is heavier and better built than most cheap imports, and a used one is worth what you pay for it because it will still be running in ten years.

What changed by year

2002 to 2009
The original bike: carburetted, kick start, three speed on the early years. Simple and cheap.
2010 to 2020
Revised with electric start, a four speed gearbox and the KLX110L manual clutch version. The common used bike.
2021 onwards
Renamed KLX110R and KLX110R L with fuel injection. Starts every time and needs no carburettor cleaning.

Servicing a KLX110

Change the oil every 10 to 15 hours or a few times a season. It takes about a litre of 10W 40 four stroke oil and there is no filter, just a screen. Clean the air filter every few rides and keep the chain adjusted and oiled.

Check the valve clearances once a year and the brakes before every ride. On the carburetted bikes, drain the carburettor before storage.

Engine hours between jobs: the schedule the Digital Garage tracks for this bike, based on the manual. Racers and hard riders go sooner, as above. Ride in sand or mud and halve the engine ones.

Buying a used Kawasaki KLX110

Look for a straight frame, wheels that spin true, working brakes and a throttle that snaps shut. On the carburetted bikes make sure it starts and idles cleanly. On the electric start bikes check the battery holds a charge. Check for a stretched chain and hooked sprockets. Cosmetics do not matter on a KLX110.
