Would any of you be so kind as to show how this is Done.

To utilize the disc brake, you need the oilhead swingarm. I understand that it bolts up relatively easily to the pivot points on the frame. However, the shock mount is inline with the rear wheel, so mainframe modifications are required to adapt the new shock location. This also means you can't use the stock battery location. Some remove the airbox and move the battery forward.

Other than that it's straightforward....

It depends what model you are fitting it too.

I am unsure about the Paralevers.

It will not fit the G/S Monolevers without a lot of work.

The frame is too narrow. You will have to move the right side swingarm pivot out away from the bike by about 1". To get the centre line close but not straight. Then you have to fabricate a top shock mount.

I looked into this and for me decided to build a twin shock swingarm extended by 100mm. A LOT easier that the other options. Again this is on a R80G/S.

I've heard that the airhead swingarms - pivot to pivot - are the same whether they're twin shock, monolever or paralever. But the oilheads are wider.

I'd think that narrowing the oilhead swingarm would be a better option than widening the frame.

Correct - I've heard that the airhead swingarms - pivot to pivot - are the same whether they're twin shock, monolever or paralever. But the oilheads are wider.

Problem is lining up the centre of the rear wheel with the bike and the shaft opening with the back of the gearbox.

One thinks it would be a simple project but is isnt.

I was going to build one, had an1100GS rear end. BUt it wouldnt fit with out a lot of work.

I though that it would be easier to build a new frame then try to get the two components I has to fit
So I looked at an old R1 frame. this would be a lot easier






What bike are you looking at fitting the oilhead rear into?
What are your reasons for wanting this?

Civil, you're welcome to have a spin on mine if you're over for a GS Event in UK

Mine is adequate with a longer HPN G/S drive train and still has good rear brake, a reliable driveshaft and about 12" of rearwheel travel.

The guy who built mine probably thought it was better to do down this route, than have to modify the back of the gearbox mount/new shock mount and re-aligning the frame

no. It works with the airhead swingarm too.

See:



The owner of the bike wrote a german How-To about the conversion. On the site you can find some more pics.

I am thinking to do this mod on my GS too and I already started to buy the needed parts.


Regards

Bernd

Interesting. When I wrote my post, I was actually thinking of maybe utilizing a K-bike swingarm and final drive, but I wasn't sure if it was the same setup as the airhead paralevers. Looking at that site, he used a K-bike part (the inner "cover") on the original airhead final drive to get the caliper mounting tabs. What rear wheel was used?
