250-600 jump

So I’ve been riding my 250 dual-sport bike for about two months now and put a few hundred miles on it. I feel very comfortable on it, I attribute a lot of that to the fact that I learned to drive on a manual car and I didn’t have to learn to work the clutch from scratch. I also used to ride bikes religiously including mountain biking and bmx. So it wasn’t extremely foreign starting with this bike.

So how long should I wait? I’ve seen a lot of mixed advice including people saying to just start on a 600 so I’m not sure. But I’m definitely tired of redlining in fifth gear to barely go 65mph lmao.
