I recently had to replace the battery on my personal ride. It was time. The original gel cel, lead acid type battery that came with the BMW was just over 6 years old and I was surprised it lasted as long as it did. I attribute it's long life to constant use. Sitting around, slowly discharging is hard on a battery of most types and my bike doesn't do much "sitting around."
When shopping around for a new one, I looked up the type and size and started checking around. One option I found, was one of the new Lithium Ion type. This is the newest, yet tried technology for auto/motorcycles and I couldn't find any downside to using one.

After deciding that it would work in my bike, I went down to my local shop of choice (
Kinetic Playground) and ordered up an 8 cell
EVO2 Ballistic battery to fit. When it came in the next day, I was very happy with the choice.
