Hmm. Each to their own, I always say. We have some pretty big guys here who ride the Savage and love it even though its small... The single cylinder makes it a unique ride and easy to chop and maintain.
My husband is 6' and he rode my bike when I was learning (to drive me to the empty parking lot). He said he liked the pick up on it. Thought it was a cool ride although he likes the power of his larger Triumph. He hasn't ridden it since, though, 'cause I'm always on it.
