Below you will find information on an aluminum motorcycle trailer I have been developing for quite some time. I was not fond of the on-bike style bicycle mount. I thought it would be unique to be able to tow a bicycle with me while riding a motorcycle. My criteria was to have a tracking trailer which leaned with the motorcycle in corners, be all aluminum for durability & lightweight, and be able to carry two bikes with gear. It can be removed when not in use. Duffel bags, coolers, and other items fit well within the middle tray when not hauling bicycles.
With much trial, error, and mid-construction changes below are photos of the fully functional trailer. It tracks great, has no odd behavior, and fits nicely within the outter edges of the motorcycle handlebar limits.
