Wife and I have Big Dog's, love 'em and don't plan to sell, trade up/dwn anytime soon. Mostly been said but here ya go:
Like others have said, give me toys to go with it (accessories, apparel that's worth a damn), open parts catalog with replacement part upgrades like bearings, bolts (speaking of, give new owners better quality of the parts, finish/chrome used to build 'em,) etc. Don't make owners rebuild their bikes if they are the type to put a few miles on em right....

We'd rather not carry around a spare parts bin with us on travels; carrying clutch cables, bearings, starters, ehc's/WP, bolts and batteries is embarrassing...esp if our HD buddies found out, (where are we to put our Beer carrying all that shit?)....

You've read Ray's and others saga's over the years - pay attention, your customers do. Make it right.
Bottom line for me, simple stuff above in my book; give us reasonable priced options and accessories...build it even better than the first and second time I choose the brand. You know the deal, take care of your customers and they will take care of you. I've bought two - the ball is in your court.
