hey, not all of the ducati riders are old. i'm 25.
track days are an awesome way to enjoy your bike. no cops, you can see all the way through the turns, no oncoming traffic.
you can run at your own pace, and comfortably step it up if you want. the setup differs between the track days, but most have pretty easy rules.
tape or remove any glass (signals, mirrors, headlight)
replace coolant with water/water wetter. (they don't want anti-freeze on the track)
have serviceable tires and brakes (depends on the track, but 75% tire, no squared off tires, and 50% brake pads left)
most require either full leathers or a 2 piece with a zip (be it 270 or 360... depends) gloves, boots, and an undamged helmet. the strictness on personal safety gear depends on the track day.
its a good idea to bring your own gas to an event... buying gas at the track is super expensive (like 4 or 5$ a gallon)
i think that covers the minimum prep required for a track day... not a big deal at all really. the ducatis are made for the track, so stripping off the street gear is simple and easy.
my personal list of things to bring:
tool set (basic stuff, hand tools, suspension tools, tire guage)
5 gal of gas
food and drinks in a cooler
canopy to shield the sun
i usually strip off the mirrors and signals, tape the head light, change the oil and filter, set the tire pressure, check my brakes, clean and lube the chain, check the radiator, tape the wheel weights, (change the tires if they need it) pack all my stuff and get everything all set a few days before. i never have the extra money to stay at a hotel the night before, so depending on the drive i either leave in the am, or sleep in the truck.
