Surfing the interweb (as you do) and I came upon something that caught my eye. A battery brand called MotoBatt, anyone 'erd of 'em?
Anywho, the one that will replace my battery (YB16AL-A2), ('97 900M) would be a MB16AU and on BumbleBee (ST4) (YT12B-BS) would be a MBT-12B4.
I'm pretty sure that Gowies stock them and they should be around $100.
