I'm not a big fan of motorbikes, but I do like the Harley Davidson and Indian bike, thanks to watching the USA show 'American Pickers'.
I know nothing about them, but I just think they are aesthetically pleasing. A bit bad ass! I wouldn't dare try them out either unless it is just around the car park riding pillion. I loved the skulls on the side of the bike as well.
Skulls give off a tough image, a bit like the tattood owner of the bike but he is a big softy.
