Hi there, I have a friend whos looking to purchace an enduro bike and was looking for a little information if possible. He's looking for an enduro bike around 600cc and has been looking at yamaha ttr's, KTM's and honda Tranalps, could you tell me if it has been documented if any of them are better suited to a tall man? or another similar bike that would suit a taller guy as he's 6ft 4in?
