I got a new battery this week from Shorai that is a Lithuim ion Iron type battery and only weighs 2.2 lbs. It is an 18 amp/hour battery instead of a 14 amp/hour battery and also has a higher CCA ratting. According to Shorai, their battery can withstand more heat, cold, and vibration than a lead acid. I'm in the process of testing it out, and intend to write up a review when I get done. Here is a link the site.

Here is what the Shorai 18 amp/hour battery looks like next to the OEM 14 amp/hour battery. It's significantly smaller in every dimension, as well as a whole lot lighter.
I got the battery installed in the bike ok. The only issue I have is that since the battery is not as tall, the positive terminal is no longer accessible without removing the battery cover plate. This also made it bit difficult to route the positive cable so it didn't interfere with getting the cover plate on. I may try to come up with a way to raise the battery up some so it sits at the same height as the OEM does. I also learned you have to be careful with the terminals, as they are not lead, and if you overtighten them, they will twist and bend out of shape.
It has no problem starting the bike and I cranked it over in 40 degrees with the bike cold soaked and it seems like it cranked a bit faster than it used to.
