You are indirectly stating the obvious, HF. No one should buy a bike that doesn't "fit" them, if they can avoid doing so, unless they know and plan to modify it and make it fit. As far as your 6'+, 200lbs+ criteria go, well, I flat out disagree with you. Although mechanical Darwinism may support your point by the numbers generally riding R3s (the bigger the machine-the bigger the operator tends to be), a more pragmatic view (i.e., that rider experience and ability count for much more than just size) seems to prevail. Otherwise, I'd surmise that motorcycle track racing would be more heavily dominated (no pun intended) by much more manly men than the sprite-like, stick figures (mechanical jockeys, in essence) who dominate the sport.
