ive wanted a nike for some time now, but i dont have a bike license. ive had a full car licence for around three years now but my heart is set on getting a bike. i just want to know: how different is owning a bike compared with owning a car, i dont really know much technical info about bikes or anything like that, is this vital though? i mean i dnt know much a bout cars yet i still drive one quite well and know when its broken lol. plus how do i go about gettin a license and do i need a certain size engine to start with? im 20 and looking at a harley davidson 1200 sportster, would this be ok to learn on? thanks
