The Roadmaster Dark Horse is a motorcycle where the battery changed mid-run: 2020 to 2024 takes the YTX20HL-BS, 2025 the GYZ20HL-C and 2026 the GYZ20HL-A. 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 2026 that means the Antigravity ATX20 RE-START: 680 cranking amps, 4 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.
