The Kawasaki KL250 takes the ATZ10 case. The Antigravity ATZ-10 RE-START is a drop-in for that case: 360 cranking amps, 2.6 lb, a built-in jump start that saves enough charge to get you home. Antigravity's list names the ATZ10 for this model; Yuasa's guide names the YTX7L-BS case for some trims. Go by the code on your old battery.

The KL250 is a dirt bike where the battery changed mid-run: 1978 to 1984 takes the 6N6-1D-2, 1985 to 1999 the YB4L-A and 2000 to 2001 the ATZ10. 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 2000 to 2001 that means the Antigravity ATZ-10 RE-START: 360 cranking amps, 2.6 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 ATZ10 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.
