Scott covered the obvious, w/out the engine running the trans will burn up. I'd say before you buy it confirm you can actually get the chain secured out of the way of every thing. Although if you need more room you could remove the sprocket w/5 nuts.
As for tie down travel, I have seen fork seals leak from being tied down.
Good luck if you choose this option. Is it worth it to rent a trailer??
+1 on removing the rear sprocket but something
probably easier and just as effective,
remove the plastic chain guard. I think there's 3 screws and a plastic pop in retainer up front. Tie, duct tape, etc, the chain to the swing arm out of the way.
I know they make front tire/bike retainers that don't require ANY TYING DOWN (they grab the front tire), but their for trailers with a flat floor and aren't cheap (definitly wouldn't work in this case nor even on my trailer (with no floor).
Just as a side note, I've towed with the above trailer (rack/ramp, tied to actual perimeter frame of the trailer), for approx 8 hours a day, with the bikes cynched down without issue. It doesn't need to be bottomed out. IMHO, half ways to 2/3's is plenty (fork compression).
I do, for overnight, when NOT UNDERWAY, release the straps abit (**make sure you re-tighten them before you leave) just to get the pressure off the front end..
Should you have a BMW (cantelever ft end-SP?) or can figure out where to cynch down the FZ
at the lower fork legs , the front suspension would have NO pressure on it and actually function while cynced down. The tabs on the fork legs (where the fender mounts would probably work but does
appear to be too low and NOT offer enough support to keep from swaying.
A BMW we took 850 miles to Deals Gap was securred this way, tied down without compressing the suspension on the above trailer. The attachment point was fairly high with the CL front end thou...
BTW, my neighbor, back in the LATE 1970's, used a very similar set up for transport. I don't remember the bike he towed but I re-call we just removed the chain with the masterlink...
