You really need to chill a little. Your statement that MotoGP riders are often smaller has absolutely no relation or relevancy to a larger persons ability to ride a motorcycle. Yes, most MotoGP riders are under 150 because weight maters in extreme racing scenarios and if riding skill was completely equal, a lighter rider will be able to go faster than a heavier rider. This is not nearly as profound as you think it is. As is always the case, correlation does not imply causation.
Furthermore, thinking that a 300cc bike is the only thing someone should get and that anything else is not only the wrong choice, but also moronic, is an equally dense point of view. There's nothing wrong with recommending a smaller bike and providing reasoning, but when you start criticizing people for the choices they've made simply because they don't agree with you, you've lost all credibility. I bought a 919 as my first motorcycle for a number of reasons. Am I an idiot because I'm 6'6" and physically can't fit on a smaller bike? Does it also fascinate you that I weigh more than 200 pounds and can somehow break the rules of physics and not only manage to mount a motorcycle, but ride it down the road without triggering a series of tears in the very fabric of space and time?
Allz I'm stating is that, in your case, better to remain silent and be thought a fool than to speak and to remove all doubt.
To the OP - Buy whatever you want, take a safety course, be careful, and ride the hell out of it. Sorry for getting salty but this was just getting out of hand here.
Let me clarify then.
1st....if you did indeed weighed in at 315lbs IN that photo....then there's been some photochoppin done.
In a normal scenario.....a heavier fellow would have a harder time manuevering a motorcycle and would be more prone to wrecking the FK outta his machine weighing in that much.
And what I meant to state was that if the OP of this thread wants to get a 650 or larger bike cause, well, a 390Ktm or a CB1 for example, couldn't handle his weight.then that's his choice. When I refer to heavier riders, 300 and above seems to be a bit more prone to NOT being able to move enough around the bike but in your case...............badmoon.........it appears you are the exception to the rule. Have you ever seen a 300lb motogp rider? let me answer that for you......NO....they usually weigh in at about a buck twenty or a buck forty. Allz I'm stating is that a smaller bike (390KTM for example) may not be well suited for a 1st time rider if that rider is indeed at 300+lbs......was I clear?
