I haul my bike with a Honda Accord all the time. I think of it like this. (How's this for scientific). My car has 5 seats, lets just use 4 of them. I figure I should be able to fit (4) 250lb guys in there and the car should be designed for atleast that, right? Well, I weigh 195, my bike weighs 195, the trailer weighs about 250, and I have about 25 lbs of gear and gas. So, 195+195+250+25=665lbs...... (4) guys at 250= 1000lbs. So that leaves an extra 335lbs. Enough for an extra small guy and a 125 ;)
