I have a 1983 GS750E and I was wondering if anyone new what is the widest tire I can put on a stock rim the still fits in between the swingarm?
 
130/90/17.

My manual says a 140/80/17 can be used as an alternative but having seen a bike with one on I think it was pinched...

I've also ridden one fitted with a 120 & that rode great too....
 
A popular mod is to put a rear rim from the later GS1150 (same style but wider) with a 140 or 150 tire.
 
Stay as close to stock as possible, maybe 1 size bigger. Your foot print with the wider tire isn't all that much more.

My bike always rode best with the stock 120 on the stock rim. 130 felt just
okay and the one time I tried a 140 I hated it.
 
Right or wrong, I don't know, but I want something a bit fatter than stock. so I have decided to go one size up on both the front and rear....

Problem is you're going to have trouble finding anything for the front. At 16", even stock rubber is hard to come by I find. With fatter on the front you might find the steering a bit heavier too, but I'm just guessing on that.

Let us know if you can find anything.

so stock size on the front and one size up on the rear, would this be a better combination ?
 
We keep wasting bandwidth on this subject.
If you want Looks, over Handling and Safety, buy a Custom with a 10" wide rear tire.:D
A wider tire on the rear actually pushes harder on your front tire in a fast lean (think about the geometry, if you can :confused:). You'll get a tank slapper.:eek:
Then you'll have to add a steering damper to help (not fix) the problem you created.
If anything, you should consider a narrower tire for rear.
Modern sport bikes are engineered for wide tires, a 83 GS 750 is not.
A narrower tire is actually cheaper.
Modern tires are pretty sticky.

Note: Its not that Harleys' aren't safe, you just don't push them in corners like a Sport Bike.

Fixerated that for you so we don't get no complaints here

Also, a bigger tire on a smaller rim puts less, lot more, rubber on the road.
 
so on a serious note....is the air valve stem a standard size, like the same as in a car rim, or is it a different size ? is it specific to a motorcycle, or can I grab a couple of new ones from my local garage (non motorcycle shop)
