some time ago (okay, many years) I bought a new Harley.
No took kit.
Dealer looks me in the eye, checks my hands (manicure) and says, "You don't need a tool kit. You need a cell phone and a credit card."
All mirth aside (hey, I thought it was funny) the only thing I've done is inventoried the stock/factory tool kit, and replaced any item I thought could be handled with one tool, instead of two, added a flat repair kit (tubeless tires, so plugs can get me home) and a stripped down $12 CDN Tire air/tire pump.
Over the years, I've added a few things, like a teeny, tiny screw driver for that one damned wire on the Gerbing jacket liner that drift's loose every now and then. And a spare clip for my 2 piece windshield. A spare gas cap for my auxiliary fuel cell, and a spare bulb for my Lightforce lights. I try to keep things on the bike that will get me home in an emergency, now the more room I have, the more stuff I have for comfort's sake. Mental comfort, that is.
