  1. Billy

    Just installed the battery in my old shovelhead a few days ago fired right up, super light and small compared to my old one. So far well worth the money, only reason I didn’t give it 5 stars not sure of the longevity and durability yet.

  2. Anonymous

    Replaced the factory battery (fourth time now in 12yrs) on my BMW K1200LT with this unit. Physically smaller, lighter, and quite a bit more powerful. My LT has NEVER cranked this easily before, even with a new, freshly charged lead-acid battery.

    Highly recommend, you will not find a better battery on the market!

  3. Moto Corsa Italiano

    Great upgrade to any bikes starting system. Great reduction in weight, great increase in cranking power and the OEM fit makes install a breeze. Truly the future of powersports batteries!!!

    Awesome product. The Antigravity unit slid right into my stock battery box. It was just a bit slimmer than the OEM unit, but the battery came with a quality foam block w/ adhesive backing to take up the “slack”. After torquing the leads, the bike fired up instantly. I don’t know if it’s a placebo effect or not, but the bike feels much more agile in the twisties. Taking 10lbs right out from under the rider can’t be a bad thing, and I think every 5 lbs removed is the equivalent of 1 hp. I HIGHLY recommend this product.

    When I got it I couldn’t believe how light it was. I must admit I was a little skepitcal, but when I hit the starter….. WOW!!!! I think I’ll have to put one in all my bikes
