Just installed some SW-Motech crash bars on my 97 R11GS. Easy install took about 45mins. Step 1 Move tank back to make for better access to the top mount bolts Fit top mount. Step 2 Remove the two 10mm nuts that secure the front of the skid plate and fit hex spacers. Fit Lower bracket Step 3 Remove rear subframe upper mount bolts and use longer spacers and bolts supplied. Fit bars, tighten all bolts and nuts refit tank and you're done. PS use threadlock on all threads and don't fully tighten bolts until both bars fitted. Easy peasy. Andy.
