On the Boxertoko GS the swing arm is lengthened by welding 2 original GS sw arms together.
I think thats the only reason that they moved the top shock mount. (they wanted to use the bmw/WP shock)

Shortening the torque arm to much might reduce wheel travel....!!!!!

Realize this is reviving an old thread on one somewhat offtopic post in it - but had this thought today after seeing/reading all the threads on "G/S-ifying" R80STs combined with some recent threads on the increasing scarcity of r100gs and/or gspds. Has anyone "GS-ified" or "GSPD-ified" a R100R? If that is a stupid and/or unworkable thing - as a mechanical "Grasshopper" I will humbly recieve my lashings.... But was just curious...

I did that to an R100R once.

Very nice! Figured if anyone - you might have done something like this.

Really wondering though if anyone's going to the trouble and expense (perhaps to spendy to be worth it?) to get the parts like fairing, crashbars/headlight guard, (tank & fender if going for PD) etc. to make it look like a "factory" GS or PD?

Many of the PD body parts (including the Tanks) are no longer available from BMW. They are going to get harder and harder to find.

18x2.50 rim for R100GS rear wheel

Hi Prutser. Just found this thread again. I am looking to fit an 18x2.50 rim to the rear wheel of my R100GS. I was just wondering if I need to offset the rim as discussed here. And if so, by how much. Any advice is greatly appreciated. Cheers, Brian.

Just a quick one here that's been nagging me: The "standard" oilhead trick of shortening the torque arm doesn't actually do anything useful at all on an airhead paralever, does it? Not on its own, that is.

Because you don't rotate the FD around the pivot bearing like on the oilheads but around the bottom shock mount, which is already nearly on top of the rear axle so a few degrees rotation won't have much effect. And if anything the bottom shock mount moves UP a bit (along the arc defined by the shock length) by the FD pivot straightening out. As far as I can eyeball it, this gets you exactly FA in extra ride height. (And as Prutser points out, potential problems at full compression.)

Ofcourse if you change the top mount too that's different...
