Vincent,

To clarify:

ANY heavy weight, whether on a rack OR on the seat, can cause the rear frame to break.

BUT so long as you do not exceed the weight of a passenger you are probably ok.

The BMW racks are about 1mm thick tubing if I remember right from the broken ones I've seen. So nowhere near as strong as the Touratech.

I would suggest taking the bike to a good welder and getting the rear frame strengthened, or go to Touratech or Wudo or HPN and see what they suggest - they aren't that far from you!

Sorry, Grant. I don´t agree on the "weakness" of the stock rear frame on a R100 GS.

I´m well informed about damages on our beemers. None of us on 2-ventiler.de knows of any issues, even heavy loaded or 2 up.

My bike did well since 1989 on many rides, and never had any issues with the rear frame.

Did you experience damage on the rear frame of a R80 or 100 GS ?
Or do you just think it´s weak??
