Good reading. I now have 2 bikes running the Antigravity batteries. Hasn't been long enough to say for sure how well they will last, but they have been flawless in both bikes so far. The cranking power is unbelievable. I had an Odyssey PC545 in my street bike, which was a big improvement over stock, but the AG is half the size and 7 lbs lighter and STILL outcranks the Odyssey.

The AG in the 690 turns the bike over a bit faster than the stock battery, but it also only weighs 2.5 lbs. Its truly hard to believe that it will work when you pull it out of the shipping box and its so light.

My only regret is that I could have used one of their small format cells instead and used the extra room in the battery tray to carry a spare tube or something.
