i cant see a dirt bike doing that... youd need to have some thick *** brackets firstly... secondly the cross bars would need to be a good 3 inch square bar... and youd have to ride your bike up onto it somehow... my bikes 15-20lbs compared to a bike thats a couple hundred pounds...

 

haven't been on in a while man, but that looks great! nice and clean...good job.

 

ya i know i was thinking of doing a slight different degn but similar because i have a short bed and am getting a tool box soon so i was thinking of make some kind of ramps that lift up similar to this design with the bike that way i could fit my dirt bikes in.
