Here's an odd question. I went riding with a friend (who is quite the beginner), and he rides an 04 xr650 which just beats the living crap out of him. Then he rode my 05 wr450 and he fell in love. "UNBELIEVABLE" he says in the difference in performance and handling. So he's gonna go buy one. My question is, is he too big? He is 6'8" and 300lbs!! He thought the xr650 would be a good bike for him because of the size, but he has a hard time starting it and it's not a good bike for trails. Any advise? Forgive for saying this, but I thought a big KTM with an electric start should be considered.
