I will be carrying 3 dirt bikes and considering buying a pickup with an 8' bed. My question is will 3 full size motocross bikes (2 * 125 and 1 * 250) fit on a pickup? I am also looking to buy the bikes and so can't test it out. Would hate to buy a new truck and find out that I still need a trailer.
3 will fit, trick is to space the middle one back a little so the bars don't clash. Have used an old car tire to do this. The angle of the tiedowns on the outside bars is kind of steep so so you gotta kinda watch it in the corners.
Can also just bolt some angle iron on your plywood with a notch cut for each bike tire.
If your truck is tall consider pulling the tailgate off when hauling the bikes. The ramp doesn't need to be as steep and it's sure easier climbing in and out to get gear etc.
