I picked this bike up saturday and did my first mod on sunday. I found the battery placement under the gas tank in the owners manual after deciding to put the charger on it. The dealer had to charge the battery before delivering it to me. I wanted to make sure the battery was fully charged from day one. Adding battery tender extension leads was a royal pain! Honda could have placed the battery in a more accessible location-like under the seat or on the side behind a panel. There's lots of intelligent engineering in this bike but battery placement is definately not one.
