***EDIT*** Quick overview if you don't want to search through the whole thread: Here's the main points. = Single wheel trailer = CRF250L pull vehicle = Modular luggage system/quick change system - Cooler - Two 5 gallon buckets for fishing - General luggage carrier [firewood, groceries, howitzer, etc] = Build with scrap laying around the garage, budget $40 - I have a lot of junk laying around, including a wheel and hub so I can probably do it. Why a single wheel trailer? Because I can. I like building things. I built a sidecar, and it was ok. Needed to be redesigned for better suspension. Thought I would try a single wheel trailer while I do more research on sidecars and design a new structure. The existing single wheel trailers out there are pretty nice and have been tested and professionally built. Most common bikes have hitches available. BUT...they are very expensive, and nobody makes one to fit a CRF250L. I can build one dirt cheap and custom fit to my bike. So, here we go. Better put in a picture before everyone gets bored and leaves. I decided to do a single sided swingarm. The hub and wheel are generic trailer stuff that is available at any farm supply or auto parts store. I sort of planned that, so that if anything happens on the road it can be fixed easily. You might notice that the wheel is worn a little unevenly. That is because it came off the sidecar, which had a little too much negative camber. If I get really energetic one of these nights, I might take the grinder to it and even it out. Bearing is in need of a repack, but that will wait until I am done with building and paint. No reason to risk getting more dirt in it with the on-off-on-off of test fitting and fabrication. Test fitting the bearings and rod. Bearings are also generic farm supply stuff. Trimmed off extra metal. Finished welding the spindle, rod, and welded on caps. Put in gussets for the pivot rod, and mocked up some sort of swingarm/shock mount.
