Debating hard on a used Grom

As the title says, and mostly the reason for that is due to being almost 42 years old, 5'10 and weigh 250...

I have dirt bikes and quads, been riding those for over 10 years just never had the space or need for a street bike. But now that I do... (commute to work 9 miles) idk if I'm too old or heavy for this fun little bike.

I've always liked the way they look and they seemed fun to own. But now I'm a bit self conscious of all this.... I'd like to hear your opinion.

(BTW, I've written Harleys on the street just never actually owned one)
