...and it does indeed, I believe, ship with an o-ring chain.
Uh, mine didn't...
Bare - it's interesting that the G5s were the first to the US (I haven't gotten to that point in the archive yet!). The discussion which I refer to is that which chronicled Kevin's October 2008 visit to Europe: "UCE unveiled at Intermot in Cologne" (http://www.enfieldmotorcycles.com/forum/index.php/topic,2680.0.html). The bikes shown in his pictures of that event were all C5's.
Don't let Europe confuse you, different timelines between them and the US.
And, I also read through the posts which described, and showed, the '08 Rally. It sounds like it was a fun weekend,
I thought that the C5's were being supplied with a mediocre o-ring chain.
