What desert or cross country race does 100mph all day long?Willow Springs for one! Otherwise, the one's with knobbies will still be regularly hitting 100+ mph (or even 125 mph in Johnny Campbell's case) if not averaging that, if one must split hairs. The point, is that you can gear any 450 MX or open class off road bike to run that if you want...it's just a matter of which one's come back as bits and pieces in a wheel barrow after 1,000 (OK 700) miles! With the Honda you can turn around and do it again. But then we already knew that didn't we?
