I've kind of stayed silent, and Bruce has given you a lot of great advice, except I have one nit to pick.
Only have exposed skin in area's where you'll be comfortable with losing it. Skin grafts are no fun.
Do this especially if you're going to be weekend warriors. The reason I say this is that most people have their heads up their asses on the weekends. As bad as they are during the week, they leave their brains at the house on the weekend.
Number one rule when riding a bike on the streets. People in cars/trucks are out to kill you. I know this sounds harsh, but it's the only way you'll survive.
I live in an area where the weekend warriors love to hang out and ride, and sadly, every weekend, someone gets to ride in the big red and white truck with all the fancy lights and sirens because they lost the arguement with a four wheeler.
I've been riding legally licensed on the streets, off and on, since I was sixteen, . I can't even tell you how many times I've had some jerk try to kill me.
Both of you wear helmets! This is non negotiable. If you want to know why, take a full bore run at a brick wall and see how good your head feels afterwards. If you're not willing to do that, then wear a helmet.
I have a co-worker who is just now getting back to normal from taking a fall at over seventy miles an hour, and he was wearing his brain bucket. Had he not been, I'd take a picture of his gravesite and send it to you. His accident was well over a year ago, and he's been having to go to rehad to this day.
I personally can attest to the helmet rule. When I was sixteen, I had a car pull out in front of me, and even though I was only going about 20-30mph, I flew over thirty feet in the air, and felt my head hit the pavement on both sides, front and back.
Anyway, Uncle Vance is done. Please heed these suggestions. I want you to be able to actually tell me,
" Geez, you were right, and I sure am glad I listened and did what you said to do."
Because, you WILL lay that bike down someday, and it's better to be protected ahead of time then remorseful afterwards.
