The dealers around here install the pigtail on everything. I use the Tender in the winter, but don't in the summer since the bike typically doesn't sit more than a couple days. I've got a set of the clips too, so I'll borrow the Tender from the bike and put it on my old truck for a day or two if it's been parked for a while. I need to invest in another Tender since I've got a riding mower now too.
