+1 to that! Try sitting on a 650R instead. At 6'1" you're just too tall for that little 250R. I wouldn't even recommend the 500R because even though I've read plenty of threads where people that are your heighth say that they do fine, they admit that they do get cramped during long rides. The 650R sits a little higher than the 500R which is why I think that it might be just tall enough for you to feel comfortable sitting on.Big bike fixes that...For such a task you either suck it up and learn on that bike or get on a larger bike. If there are adjustable rearsets you can adjust them to your needs but do not expect super monumental adjustment. Just being honest.
