Gilera 125 RTX Kick-Start Battery Replacement - Motobatt MB5.5U AGM
Gilera 125 RTX Kick-Start Battery Replacement - Motobatt MB5.5U AGM
Warranty
The Easy Part of Keeping an RTX Running
Same case, more inside: the MB5.5U packs 7.0Ah and 90 CCA, against 5.5Ah and 44 CCA in a flooded 12N5.5-3B. Those extra amps count most when the RTX struggles to start in the cold.
- Posts doubled for each polarity - your leads connect on either terminal layout.
- The case size every 12N5.5-3B shares - 135 x 60 x 130 mm from base to post tops.

Frequently Asked Questions
Is it hard to find a battery for a Gilera in the US?
Not for the RTX 125. Its battery is a size that many bikes and scooters share, so you shop by the size code on the worn-out one, with no Gilera part number to chase.
What size battery does the RTX 125 take?
A 12N5.5-3B. That code sets the case size and where each terminal goes. The MB5.5U shares that case and works with that terminal layout. If yours is marked differently, call us before ordering.
Is HTBS connected with Gilera?
No. We're an independent battery seller, and nothing ties our company to Gilera. Motobatt builds the MB5.5U, and we sell it and help you confirm the fit.
Give us the label code off your RTX's battery. We'll confirm the match, so the battery stays the easy part.
