The Honda Sportrax 250 takes the YTX12-BS case. The Antigravity ATX12 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.

The Sportrax 250 is an ATV where the battery changed mid-run: 1987 takes the YTX12-BS, 2001 to 2020 the YTX9-BS and 2021 to 2026 the YTX12-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 2021 to 2026 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.
