i got 3 questions really........?

i gonna buy me a bike this is what i want honda 600 shadow deluxe but i also thinkn about the kawasaki 750 vulcan. the shadow is what i prefer. i ve rode bikes all my life not a beginner at any means just a small guy that wants a low seat height and not a big bike, if i cant touch the ground flat footed i dont need it. sold my goldwing cause i could barely hold it up ....... next ? when i ride my 250 rebel why do all the other bikers kinda laugh at me. i guess they think i'm a beginner or someting i had the bike since i was 14 and i 31 i love my lil bike so what could be the deal.
