Seat height Honda 125cc 1992?

I'm approximately 4'11" and weight about 81.6 pounds, would I fit the bike?

If you mean a Honda CR 125 than no, it would be a struggle to throw a leg over it.

You'll fit a Grom, guaranteed.

Most probably no, I'm 5'6 and I can't touch the ground with flat feet on my 50cc bike, although it has a very high seat.
