Dirtbike carrier for XJ???

I took the xj out last weekend and we went to a place where theres dirtbikes, quads, and 4x4's. Well we stopped for a break at the entrance after a few trails and saw this guy pull in with a stock xj with a dirtbike on the back, and ever since i sold my truck and got the xj i've been looking for a way to haul my dirtbike, without buying a trailer. And i'd never seen the carrier that he used on the back of his jeep, it looked just like a bike carrier for a pedal bike, but a little beefier.
Do they sell dirtbike carriers for xjs? and if so, about how much do they run for?
or was it something that this guy just fabbed himself?

Check out dennis kirk i have seen a few of them on there an there really not to expensive.

PM Jeepernick... pretty sure he bought something like that for his XJ.

DR

You can order them for your hitch receiver to load the bike on and haul it there.

I built one in about 2 hours to haul my yz250f. its easy.
