1991 BMW-Motorcycles Background Info
The 1991 BMW-Motorcycles Vibe
Welcome to 1991, an era where BMW was busy proving that a motorcycle could look like a futuristic space pod (the K1) or a desert-conquering beast (the R100GS). This was the year of high-vis graphics and bold statements. While some folks were distracted by the neon windbreakers and the Berlin Wall coming down, we were looking at the paint. Our records show that for 1991, we've focused on the survivors-specifically the deep, metallic Blue that defined the K-series and the R100RS. It's a color that says "I have a mortgage and a passport," and it looks just as fast today as it did when Nirvana was still an underground band.
Paint Health Check
If you're riding an original 1991 Beemer, you're officially in The Peeling Era. By the early '90s, BMW had fully committed to multi-stage systems-stacking a lush color base under a protective clear coat. It looked brilliant in the showroom, but here's the rub: those early high-solids clears are prone to "Delamination." On those massive K-bike fairings or the R-series tanks, a small stone chip isn't just a cosmetic blemish; it's an invitation for the clear coat to start lifting away from the color coat in sheets. Once the air gets under that clear, it's a slow march toward a total flake-off.
Restoration Tip
Listen closely: you need to seal your chips immediately. If you see a tiny white-edged nick where the clear is starting to "bridge" or lift, don't wait for the next service interval. Take a fine-grit applicator and some high-quality solvent touch-up to seal the perimeter of that chip. By bonding the edges of the clear coat back down to the base, you stop the delamination in its tracks. If the clear has already started to lift, don't just "blob" paint over it; you've got to carefully feather the edges of the failing clear first, or your repair will just peel off like a bad sunburn.
