Triumph is legendary! That is what a guy on a custom chopper said with his aussie accent last Sunday when he pulled up at a red light. We take away from them being the only 100 year bike company and deminish their badboy (girl) mistigue. We show there is a choice and that bothers some of the younger Harley owners. The older ones have no problems with Triumph.
On the flip side we all talk like they are just into image rather than riding as we sit on our Triumphs posing lol. We have a great deal in common actually :-) we are just fewer in numbers.
I don't know anybody that really hates Harley owners nor do I know any Harley owners that hate other bikers. Its all just fun blustering. Bikers have very complex egos. Like a sports car the bike becomes an extension of your (snipped) personality.
