A forum for the discussion of your sidecar, Conversion Trike or Pull Behind Motorcycle Trailer.
I said to phone Frankenstein because they will give you an exact measurement. I myself think it would be 58 inches wide plus add 2 inches for each fender overhang which would make it 62 inches total but I can not guarantee that but they could
My Wide Glide using the 38" Sport Trike axle, along with the upgraded wheels, 265/50 tires, and 12.75" round fenders measures 51.75" outside fender edge to outside fender edge.
Hope that can give you an idea of the width you're looking at with the rear axle and fenders.
