Here is the starting point of a cheap sidecar built with readily available low tech. 1983 XS650 yamaha rat adventure bike and a 1980 CB650 honda rear wheel and swingarm. They both have the same size rear tire.I will post photos as I build this rig so some of you who would like to try hacking can get an idea what can be done for cheap. This rig is also for sale $795 for the bike or $995 for the completed rig. I am building this rig for my personal use so thanks in advance for all the warnings about danger. I have ridden my home built rigs as far north as the arctic circle and as far south as mexico city. I just brought home some salvage angle iron from where I work...it will work well with the salvaged honda and yamaha 4 wheeler packing crate rectangular tubing.
