Backrest mounting

[sbg]

I have been trying to get a passenger backrest/luggage rack for my '83 gs1100g and am not having much luck finding one. If I knew what models will fit what bikes it would make things easier, or if I even knew where they mount that would be best.

I know the front mount on the backrest usually mounts on the shock mounts, but can anyone with my bike or similar tell me where the other mounting points are? There doesnt seem to be anywhere else on my bike for the rearward backrest mounts to anchor to.

TIA.

Usually mounts like you said to the shock mounts & also to the turn signal
mounting point

I just fitted a grabrail to my GS1000E - there are 4 studs in the
rear of the seat that can be removed - I'd guess you could also
mount a backrest there (Actually I'm after one too!).

Thanks for the replys.

I had thought about the seat as a mounting point, but Im not really comfortable with seat pan as a structural support.

I will take a closer look at the trun signals.

On my 83 1100E the rack/backrest attaches to a fabricated frame that bolts to the shocks and to the turn signals mounts.
Could be possible to do the same with your model.
Best place to find backrest is eBay it seems :?
