I have 2 Hayabusas and don't have a truck. I am going to use my 2004 Grand Prix to tow these on a 5x8 trailer. The total weight with trailer and bikes = 1360+ pounds. I have did good maintenance on car and am adding a transmission cooler to the car as well. What are your thoughts of me hauling the 2 bikes to black bike week from columbus, ohio? Has anyone done this before?
