The Piaggio Fly 50 takes the ATX12-AH case. The Antigravity ATX12-AH RE-START is a drop-in for that case: 360 cranking amps, 3 lb, a built-in jump start that saves enough charge to get you home. Antigravity's list names the ATX12-AH for this model; Yuasa's guide names the YTX7L-BS case for some trims. Go by the code on your old battery.

The Fly 50 is a motorcycle where the battery changed mid-run: 2009 to 2010 takes the YB9-B and 2017 to 2019 the ATX12-AH. 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 2017 to 2019 that means the Antigravity ATX12-AH 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. Antigravity's list names the ATX12-AH for this model; Yuasa's guide names the YTX7L-BS case for some trims. Go by the code on your old battery. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
