That's not really how I meant it.
If you're not confident enough in your skills to try it yourself, and have to ask someone on the internet if you're ready (note we have NO WAY WHATSOEVER of accurately assessing your skill set OP) then you need to go an sit in a coffee house for a while and ask yourself if you think you can do everything right every time. A modern 600 will punish your mistakes, where the 250 will usually let them slide. If you feel confident enough in your riding of the 250 that you think you won't make any mistakes from now on it's time to move up. If however, you often or even occasionally say inside your helmet,
"why did I do that"
"that could have been bad"
"dumped the clutch, fuck"
or any iteration or similar idea...
Well you get the idea. The 250 that you have is the place to perfect your muscle memory. If YOU fell you're there then move up IF you want too. Not because people give you a hard time about what bike you ride. Not because you think you need more power to keep up. Not because it's what everyone else does. But because it's what you want.
Hope this helps.
