Motorcycle and Scooter appreciation

Just turn 20
Had my full licence for 3 years now looking to purchase my first big bike
Been riding a hyosung 125 for the pass 2 years just like some advice as to should I jump straight to a 600 or take it easy and get a 250?

Sell your Hyosung to Tanya.

I got a 400 and was glad I did.
It was a huge step up from a 125, it took me a year and a bit to crave more power.
When my two years were up and I got the triumph it took me bloody months (and a crash) to gel with the thing. If I had hit it straight from a 125 I'd be dead.
