The Kawasaki KLX140L takes the YTX7L case. The Antigravity ATZ-7 RE-START is a drop-in for that case: 150 cranking amps, 1.3 lb, a built-in jump start that saves enough charge to get you home.

What the KLX140L needs, in plain English

Every KLX140L from the first 2008 model through 2020 starts on the YTX7L case, a 12-volt starter battery. Kawasaki ships it with a lead-acid battery that starts to fade after two or three seasons of short rides and off-season storage, and that is usually the day a rider goes looking for something better.

The lithium drop-in is the Antigravity ATZ-7 RE-START: 150 cranking amps, 1.3 pounds, the same case in lithium. Its RE-START function puts the battery to sleep before a parasitic draw can drain it, then wakes it with one press for a jump start. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.

What size battery does a Kawasaki KLX140L take?+
The YTX7L case, the same one on every KLX140L from 2008 to 2020. The Antigravity ATZ-7 RE-START is the lithium drop-in for it.
Will a lithium battery work in a KLX140L without changes?+
Yes, on a bike with a healthy charging system: the lithium battery uses the same case, the same posts and the same cables, and it drops in where the lead-acid battery sat. Bikes older than about 2000 should have their voltage regulator and rectifier checked first, since a failing one overcharges any battery and lithium tolerates it less. Fill any gap in the tray with the foam spacers most lithium dirt bike batteries include.
Do I need a different charger for a lithium dirt bike battery?+
Use a charger or maintainer with a lithium (LiFePO4) mode. A lead-acid trickle charger can push the wrong voltage profile, and a desulfation mode can damage a lithium pack. A lithium-profile maintainer over the off-season keeps it topped without harm, and the battery loses only a few percent of charge a month sitting on its own.
