yes....I got my battery from OrientExpress.com. It is called a "A123" battery. Works fine, and recharges through the stock bike charging system. I ran mine down bad.....I put it on my battery tender for 2-3 hours today, and it jumped right back up!
They are PERFECT for a Cafe bike, IMHO.
(not so sure any pics of my bike should have made this thread....this is the dream bike thread, not old, tired CB550's thread)
