Antigravity AG-1201
Small Case Lithium 12v Powersports Battery
The Antigravity AG1201 battery has 360 Cranking Amps yet is only 4.50 x 3.25 x 4.25 inches (LxWxH to top of terminals). This lightweight Lithium motorsports battery weighs only 2.25 lbs and is a great choice for those seeking very high power in a compact battery. It can replace the typical 12Ah lead/acid battery with a weight savings of up to 7 pounds while offering much more cranking power.

Since day 1 my 2009 Aprilia SXV cranked slow and had a hard start problem…especially in the cold. I installed a 12 cell AnitBravity battery and the problem is solved. Cranks faster and starts reliably.
Now I dont fear getting stranded.

I am building a L/S bike (long/skinny) using parts I’ve had for years. The front end is a Harman 15″ over girder that I used on a 39 knuck in 1974. Using that front end as a starting point an building a copy of that bike but thus time I am using an Evo engine. Order a teardrop oil tank that was supposed to allow the use of a stock SoftTail battery. No way but the tank maker sold Antigravity batteries. I ordered direct from Antigravity, not wanting to deal with oil tank maker. Got the battery it fit and starts the 8o” Evo easily. Very happy with product. If you can afford one buy it thanks, The Grandimagineer P S. I am a 70 year biker and Mustang Person. That has been building bikes and Mustangs for many a year
