I have read all the post on strapping down and trailering your bike. I have a 5x8 landscape trailer, I put a 3/4 pressure treated floor on it and a Wheel Chock. I have for D- Rings and would like to know where to mount them. DO i mount them in the center in the front to pull the bike in the chock better. DO i put all four in front (all straps goign forward) I have never hauled and i have a 06 sportster. ANy suggestions on where good points on the bike would be to place the straps? I am finishing the trailer tommorrow and hauling wed. JUst nervous. THanks GUys.
