Here's the trailer I built from an OLD boat trailer, the frame of a rollup bed cover, and about $50 worth of steel and hardware. I called it my "lite" trailer. The local Cat scales couldn't weigh it, meaning the entire trailer weighed less than 200 lbs. Because I couldn't get it officially weighed, I couldn't get it titled here in PA, so I gave it to my brother in TN where it is legal as is. My brother is actually considering using it tow his wife's dirt bike behind the family's Honda PC800. It pulled a single bike like a dream. I had my YZF600 on it numerous time and most recently the CR250. When my dad pulled it to TN he had his old XR650 on it with nary a problem for almost 900 miles. If I built it again, I'd mount a rack to the front to bolt a tote or an aluminum box to carry riding gear and basic tools. That said, most of the time, I just load the bikes in the truck. My Ram 2500 with 33 inch tires and factory HD package sits pretty high, but I've never dropped a bike off the truck or had a tailgate break. For ramps, I have two 10' long 2"x10" boards covered in expanded steel mesh. I've loaded the street bike while it was snowing and still had traction.
