1985 GS1150E Rim size question

[Slowhand]

I have an 85' 1150E that I bought new. I wrecked the bike years ago, wiped out the front end. It's been in my garage since with my others bikes, I loved that rocket and thought I'd fix it one day, it only had 12,000 on the motor. Well 'one day' has arrived, late but it has arrived.
The rim sizes on mine are a 16/2.75 front and a 17/3.50 rear. I have found a 16/2.50 front rim, forks and triples that I'm told are from an 84' 1150ES. My question is would these work on my 85'. Can I fit my 120/80 Metzler on that narrowed 2.50 rim.
Any answers or insights would be appreciated.

thanks

Thanks guys. What's amazing is my Metzlers still look new, no age cracks or anything. I will replace them before I start riding the bike. For now I just want to get my old front tire on a rim and the forks in so I can move it around on wheels to continue working on it. It's been on the centerstand with the bent forks and busted rim lying on a dolly. Pain in the ass to move it around with the jack all the time.
I didn't know the 84's came with that smaller size rim. Anyone know if that would affect the handling using the 2.50 up front and the 3.50 in the rear? I'm guessing probably not.
anyway, thanks again, I will probably be back on here quite a few more times as I try and get this ol baby running again.
