Most thefs is opertunists if thay can get get something for nothing thay will. However thay are not going to work too hard at it. Most locks and chains will not stop somone who REALY wants your bike. I have used bolt cutters, Sawsall (like a big jig saw), drils, hack saws, cut off disc on dremils, even liquid hydrogen once. Thay all cut or brake locks and chans or what thay are chained to. A disk lock gust means thay need to pick the bike up, thay probly will do that any way to get it in to a van.

What you want to do is just make you bike less of a target. Get a old tent and cut it up to fit around the bike and bags you will have get it sown up so it covers the bike up. Get your new cover good and wet and stor it so it molds up real good, so it smells and stains wash it and rewaterproff it on the inside. Now for the fun part pee on it! Get a cat and dogs to pee on it. No thef in there right mind is going to spend there time and chance geting cought trying to steal what ever pice of crap is under that tarp. In South America people take pride in what thay have and beleve others do the same.

Most small town thefs wont steal your bike, its to grate a risk thay wont beable to move it and probly dont know people that can fence, your geer is that there after. Small, expensive, eazy to move, prfitible. The odd pro that is set up to steal bikes and cars has fences and will likly already know where your bike is how much its worth may gust part it out, old beat up muddy over land bikes dont tend to sell well, most people see a bike like yours will know its stolen.

If all this fails gust get a bike in SA like a 400cc job there cheap, easy to fix, small, and all you realy need. A bit more of a target but you pee tarp will help that.

The pee tarp works for me in citys in the USA, I put on a light cable and a lock for looks
