If the chain broke on a fellas concentric drive ATV, could he put it in AWD and make it back to the truck? How does this work? The guy at the delaership was very polite, but really just said that the concentric drive was "very reliable."

Thanks,

 

Don,t know about on the concentric drive but I saw a guy break a rear chain on a 96 explorer 400 4x4 and he drove the thing the rest of the day with only the front wheels pulling, wild looking front wheel drive quad. I would think the concentric would do the same. I ride with several 400s with the concentric drive and it has proven to be much better than the old style setup at maintaning proper tension even when jumping.

Flash,
I wondered the same thing about a year ago... IF I broke the rear chain, WOULD it make it home under its OWN power.?
While making a sprocket and chain change, I put everything back together EXCEPT for the chain, and fired it up. I drove it in AWD and it pulled fine. The only problem I noticed was EXTERMELY difficult turning, I guess thats because it "sensed" that the rear wheels were spinning BAD... So, to answer your question, Yes it will, as for whether or not you'll be tired when you get to the truck, My experience with it would lean on the YES side...
As far as it being Concentric Drive System (instead of the NON CD System) that just has to do with the more consistent chain tension throughout the suspension travel..

 

The pivot axis of the swingarm on a concentric drive ATV is aligned with the countershaft sprocket, therefore keeping equal tension on the chain as it traverses up and down. It is actually easier to maintain as well, when adjusting chain slack. As long as the quad is on a level surfeace you can get an accurate measurement of the slack without worying about the chain stretching when the rear shock is compressed.

As far as driving in front wheel drive, that shouldnt be a problem, if you must.
