Antigravity AT12BS 12V Motorcycle Battery 360CA (w/ Re-Start, Thin Case)

Antigravity AT12BS 12V Motorcycle Battery 360CA w/ Re-Start: The Thin YT12B Case, With a Jump Start Built In

Yamaha's V-Star 650 ran a YT12B-BS for seventeen years; so do the FZ6R and the Triumph Bonneville, Thruxton and Speedmaster 865s, Ducati's Monster, Multistrada 1200 and Diavel, and the FJR1300 and Raider on the taller YT14B-BS. The AT12BS RE-START replaces all of them at 2.3 lbs with 360 cranking amps and a jump start built into the battery, for $40 less than the heavy-duty version.

The thin 2.75 inch case is the point: it fits the narrow trays these bikes were designed around without shims or a hacksaw. The RE-START BMS sleeps the battery before an alarm or a long sit drains it flat and keeps a reserve. Press the button on top, hit the starter, ride.
