Been on a dirt bike since I was 4. Been on the road for a few months now(I'm 22) cause I just bought a CA plated xr600r
Few things I've learned about riding on the street are:
If someone's on your ass and you're going the posted speed, let em pass, it's not worth letting some asshat push you to go faster.
(Noticed this after I saw guy I was riding with down SH38 almost get taken out turning left when a driver behind us saw it necessary to pass on the left on a two lane highway just 'cause 55 wasn't fast enough for him)
Screw the 2 second rule, i take 5.
Always tap the brake to flash the brake light.
Riding at night sucks.
Choose good tires.
Ride like you're invisible.
