The Honda Sportrax 450 takes the YTZ7S case. The Antigravity ATZ-7 RE-START is a drop-in for that case: 150 cranking amps, 1.3 lb, a built-in jump start that saves enough charge to get you home.

Shop all Honda ATV batteriesWhy the year matters on this one
The Sportrax 450 is an ATV where the battery changed mid-run: 2004 to 2005 takes the YTX9-BS and 2006 to 2013 the YTZ7S. 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 to 2013 that means the Antigravity ATZ-7 RE-START: 150 cranking amps, 1.3 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.
