Introduction: 1991 ST1100 Darkside
Going to the darkside, other than Star Wars, is the use of a "properly fitting" car tire, in place of the rear tire (most popular) or both front and back of a motorcycle. This is a documentation of my conversion process.
It is important at this stage to note that there are time and resources invested in this project for those who want to do this conversion on this model. If you don't have a metal lathe, you will have to provide the necessary blue prints and money to assemble these parts with a rim other than OEM. These parts include a modified brake caliper hanger, different length spacers on the axle and a spacer underneath the 5 lug spline spider. The rim you need is 16" instead of the OEM 17" to faciliate a tire that will mount. The Goldwing rim is more narrow than OEM, these spacers and modifications aid the shift of the appropriate distance to the left so the wheel is centered.
