Unless you have a short wheelbase bike, you will have to fit some sort of sidecovers, otherwise you will have again a big empty space that needs to be filled.

I intend to keep the airbox to keep that engine shape. As you say, I think it looks weird without and I'm not keen on those bikes where the battery is just bolted in place of the airbox. I reckon that one of those lithium batteries should fit, I need to make a cardboard mock-up really.
