My first ride was in the Yardley factory parking lot in East York in 1965. I was too short to reach the ground from the saddle so I had to launch from a curb or take a rolling start before I threw my right leg over the saddle. Stopping involved sliding my butt off the left side and hooking my right leg over the saddle so I could touch a toe to the ground once I came to a complete stop. :I in those days all the bikes had the same seat height even if it was only 80cc, manufactures went out of their way to make the saddle that tall.
The very best place too first ride a motorcycle is on a grassy field or the flat bottom of a sand pit. Makes crashing far less painful and you will break far fewer levers.
Specs are very important when you are shopping for motorcycles, but you have to learn how the specs relate to results. Massive front brakes on a bike is an easy visual key, should be easy to spot, if the brake disc's are nearly as large as the rim and there are 2 of them, those are probably powerful stoppers.
I think Hyosung 250 pictured here is the only 250cc bike with huge looking dual disc brakes that don't really work like huge dual disc brakes.
China likes to put stuff on there product so they can list it as a sales feature on the brochure, not because it needs it or is better. Brakes on that particular bike don't actually work as well as one good brake disc fitted with a decent calliper :| while they look like the real thing they are poor value. Those hyosung callipers are crap and the wrong thing to put on that disc which was made to look like it is on a radial calliper equipped bike.
When shopping for disc brakes the most important feature is usually the number of active hydraulic pistons in the calliper. Two beats one, particularly if they push against each other, 4 piston brake callipers is the performance spec of choice to look for, but you won't find them on anything less then a high performance brake.

Honda CBR250R vs. Hyosung GT250R vs. Kawasaki Ninja 250R | MC Comparison
"Although it has twice the front brakes of the Honda and Kawasaki, the Hyosung’s squishy lever takes double the effort and has practically no feel."
... squishy brake lever action on a hydraulic brake is either the result of air in the system, stretch in the rubber brake lines that should be steel reinforced or poor design of the calliper. In the case of the hyosung example I would suspect the rubber brake hoses and poorly designed callipers to be the source of the problem the test riders noted.
