What the MC 250 needs, in plain English

Every MC 250 from the first 2022 model through 2026 starts on the ATZ5-X case, a 12-volt starter battery. GasGas 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 ATZ5-X: 170 cranking amps, 1 pound, the same case in lithium. 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 GasGas MC 250 take?+
The ATZ5-X case, the same one on every MC 250 from 2022 to 2026. The Antigravity ATZ5-X is the lithium drop-in for it.
Will a lithium battery work in an MC 250 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.
