83 GS750ES swingarm mod?

[baz666]

Hello all,
My 83 GS750ES has a backtire that's 130/90/17. Is it possible to someone convert to a wider swingarm so I can fit in more reasonably sized and more modern rear tires?
It looks like the 130 is the absolute limit and barely clears the swingarm on the righthand side (as sitting on the bike).
thanks in advance for any advice.

Here is my 750, it has an '89 gsxr rear wheel with a 160/60 Dunlop Roadsmart on the stock rear swingarm. There are several other members who have done this also who i'm sure will post up some pics.

Full side view. Front end is RF900 with matching gsxr wheel. Fairly easy to swap parts, mostly bolt right up with some slight tweeks.

Topside shot. Handlebar setup suits me.

I run a 170 profile pilot power in a stock swinger. It's actually the chain that limits it at that point as you can't move it out any more and get good frame clearance at the front.

With a frame modification to build a box for the chain to pass through a 180 could be made to fit easily.
