Shop all Moto Guzzi batteriesWhy the year matters on this one
The California Stone is a motorcycle where the battery changed mid-run: 2005 takes the ATX12 and 2006 the YTX20CH-BS. The plate above names the source for each year, and the table shows every run we have on file, so match the year to the case before you order.
For 2006 that means the Antigravity ATX12 RE-START: 360 cranking amps, 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.
