On loading my Motorcycle (2006 Honda Goldwing) onto a trailer while using this ramp, a tire of the motorcycle, after rolling over the hinge which sticks out over the ramp's traveling surface, shifted to the right and the heavy motorcycle became unstable, it felt to the side with me on it, saved by the motor guards only. As-is, this Ramp, as a result, would be fair to fall considered as neither useful, nor safe for Heavy Motorcycle Loading. A fatal defective condition obstructs the chiefly needed center lane for the Motorcycle tires traveling, where the tension would have a more even distribution of force and added to the stability and strength of the product. This grave deficiency would appear to render the whole structure unstable, thus, perhaps unsafe of use, as the ramp would tend to freely "butterfly" open when weight is added to its center and hinged platform side -this as based on laws of physics and commonsense. Moreover, and possibly hurtful to shoppers, seller fails to depict in pictures this conspicuous grave defect when advertising. Reversing the hinges to the untraveled on side, would have created a counterforce to prevent the splitting and separating of the two sides of ramp, when heavy weights were applied to its center.
