Just basics. A tall windshield and some locking cargo cases (not sure of the right term). Those leather saddle bags look cool; but too many people have sticky fingers.
Skip the ugly tall tall winshield.
Get a WindVest instead.
We can get just about anything you want from Custom Chrome, Midwest Cycles, etc but you should shop around eBay for the hard bags, first.
They sell leather bags with locks, ya know.
One example of many.
