    My rig is ok for fork springs. It's got heavy duty progressives in the front which I think have some extra preload spacers installed. When I first got it I thought the forks where seized. They are infact just stiffly sprung, so no probs there.

    The rear and the sidecar springs are a different matter entiery though. On the twisties it's quite possible to suffer from sea sikness :D

    That's called a "schwabel", being put together from "schwinge" and "gabel" in German

    ( meaning "swingarm" and "fork" )

    That's interesting. Glad to know it has a name 'Schwabel' sounds good too.

    Ah, I had momentarily forgotten about those being in my own plan!

    I know this thread is quite old now but I wondered how Val was getting on? I also like the look of the modification you are thinking of.
    I am new to all sidecars never mind steering geometry but wondered if it would not be easier to re-machine some yokes with a different angle for the forks? Does this do strange things when turning? why is it seemingly not favoured?
    Thanks

    Well I haven't stopped thinking about this mod. My main reason for not getting this done is simply time and money.

    However my main plan has been kiaboshed. Whilst measuring up I discovered that to put the front wheel exactly where I want it (down 100mm and forward 40mm which would raise the ground clearence and reduce trail), the bolts/bearings that would need to go through the front wheel spindal clamps to mount the swing arm would foul the discs. The only way round this would be to machine the inner edge of the forks. Doing this presents another problem. Machining the inner edge of the forks would remove the inner clamp bolts. So not being blessed with the nesassary welding skills I have decided that I need to find an alternative design.

    Over the last couple of months I've been soarcing reletive SH parts at the right price. Such as a set of upper and lower yokes from a K75 for £19. With these I can at least make up a set of traditional LLs, but I might yet go down the route of simply fitting a pair of off road forks the same size, though I'd like to keep the OE wheel, haven't decided just yet.

    In the mean time we'll be moving house in a few weeks (going to hold up at my Dads for a while). Then in a couple of months (fingers crossed) we'll be relocating to the west coast of Wales, where the new house (fingers crossed the money man he say yes) has a massive workshop where I'll have plenty of space get stuck in to this project. Providing I manage to get the time of course.
