gsxr 1000 swingarm swap for my 700es

[seann]

im looking for any info on a swingarm/shock/wheel swap from a gsxr 1000, to my 85 gs 700es. there was a guy who had done this swap and was selling the 700e on ebay a few months ago. he said he got the info from gs riders.com and i looked it up and came up with a bmw site. well i emailed this guy and he said he would email all the info that i needed and i never heard back from him. i was wondering/hoping that someone in here would know anything about this swap, or info where i can find it. i am in need of a larger wheel for the back of my gs. (fat guy little wheel) just doesnt look right to me. thanks for any info.

I think you could probably make it work but you would probably have to use a offset front sproket, and you probaly couldnt use the front sproket cover,
you would allso need to have the frame altered with a difernt shock mount on the frame, positioning this mount would be really importent to get the rear shock to work, if wrong the rear end suspension locks, the chain run could allso be a problem, and there allso be fabricated some internal swinging arm pivet adapters converting the swinging arm shaft from the standard large shaft to the one the GS700 currently uses.
is it all worth it... I duno its up to you

Right on all counts. But you can modify the sprocket cover to work quite easilly.

I also converted to a mono shock setup.

Either way, a bit of a job.

then what else could i do? i would like more tire, and it really does sound like alot of work for just that. i really dont want to chop my bike all up. its in to good of shape to hack it up. i dont mind a little modification but i would like to keep it simple. thank you guys.

I am putting on a 92 katana rear on my 700E right now. It's a 140 rear and I am suprised on how easily it's going on.

You don't need more tire to corner harder.


Race bikes had 130's and 140's for years and years - and they were dragging knee just like Rossi on a 190.


Bigger doesn't mean better - it means that the tire has to travel farther to lean into a corner, and it means slower turn-in, which is important when you have a bike that weighs as much as your GS.

If you're wanting a larger tire just for looks - ride your GS as-is until you've got the money to buy a bike with larger wheels.

If you're wanting a larger tire because you think it'll allow you to corner better, just take your GS to a track day and find out just how far over she'll actually turn without sliding out.


If you're wanting a larger tire because of the limited selection of tires in the 130 range, you can get DOT slicks for your bike - but this is a valid challenge. You can upgrade your wheels to wider early Katana wheels and run up to a 160 in your stock swingarm, with minor modification to the drive sprocket and sprocket cover.

Changing a swingarm and a front end are not incredibly difficult, but getting the parts, fabbing spacers, and making everything work right can be expensive and very time consuming.

I'd start by getting an aftermarket rear shock, new fork springs, a fork brace, fork preload adjusters, and stainless brake lines for your bike first - these are all simple bolt-on upgrades. After you've made it handle and stop as well as you can, then you should look to upgrading the wheels and calipers. If you're outriding the bike at this point, then you should look at getting a more modern bike.


Unless you're just looking at modifying your bike as a hobby - then hack away. Doesn't matter what the cost is at this point...
