The Kawasaki Ninja 650R takes the YTZ10S 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.

The Ninja 650R is a motorcycle where the battery changed mid-run: 2006 to 2011 takes the YTX12-BS, 2012 to 2016 the YT12A-BS and 2017 to 2021 the YTZ10S. 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 2021 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. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
