I still want to see someone actually load that thing. I've got those wheel shoes in a trailer, and the bike needs to be perfectly aligned. Putting the front tire in the chock with the rear still on the ground would be a guaranteed way to bend the front rotor. The whole bike would need to be on the tube and roll forward before locking in place. I'm trying to find pictures, but I remember seeing a guy show up at a race here. He had an old Corolla I think it was at least, that he took a cut off wheel to and made into an El Camino chop job. Removed the front console and back seat, cut out some more of the roof, and put some eye bolts in what was left of the roof. No idea how he actually drove it to the race.
Ha, yep. Just picture that with like an '88 Corolla sun faded burgundy paint mixed with rust...and an $8k dirt bike in the back.
I could see myself driving off with my helmet on the workstand and gas tank all untethered. I get home and start looking for them -- DOH!
Instead of a single rear wheel, I think it would be better with a dual wheel setup with the axle further forward under the rear wheel of the bike. You could cut significant length off the trailer that way, and incorporate a stowaway ramp to facilitate loading the bike from the rear.
Interesting conversation piece! However, I see no practical advantages to the trailer but too many disadvantages to list.
