While driving on logging roads with my Ct90 on the harbor Frieght receiver rail I hit a number of potholes. The bike bounced came loss and I couldn't see it in my mirrors. I stopped and found the CT laying on it's right side on the receiver rails. I had strapped it tight and the straps held it from a complete separation. I unstrapped and reloaded, restrapped and took it easier and watch the potholes. It seems to have not hurt the Ct90.
