Main thing is what feels good to you, to sit on and ride. Everyone is different. My first was a Suzuki Bandit 250 - test rode several bikes and it just 'fit' - I liked the seating position, and the balance. Had it 2 years and never dropped it because she wasn't top heavy, we did loads of kms (including a trip from Welly to Invercargill - down the west coast and up the east of the south island). Test rode quite a few bikes in the months after getting my full license before I finally found one I'd trade my baby bandit in on. Good luck :-)
Look where you want to be, as far ahead as you can see and always enjoy the ride.
