1980 gs750L , what size is the front wheel

[Headphase]

I'm at work, and the bike isn't, so I apologise for the dumb question.

I want to order a new front tyre and can't remember the size.
It's a standard 1980 gs750L model, can anybody remind me what size wheel it has. Save me waiting till I get home then losing a day ordering a tyre.

thanks

is it a 90/90 19 ? And if so, can a 100/90/19 fit?

My wife's 850L is wearing a 100/90-19. (Cheng Shin Hi-Max)
My son's 650L is also wearing a 100/90-19. (Kenda Challenger)
I see no reason to belive that your 750L would have a size other than those.

I believe that 90/90 might have been stock, but the 100/90 is a little larger, which slows down the front wheel, making the speedometer near-perfect. \\/

thanks Steve, much appreciated.
I'll wait till I get home and double check what is already on there, no point rushing things when it's taken a year to get the bike road ready anyway, eh

I think all GS's but the 400/425/450 take a 19" front tire.
