Wow, this is your first bike and you're older than me! I'm 47 and just started riding 2 months ago (after having taken my New Rider course exactly 2 years before that). Congrats and welcome.
We also both have bikes built in the 80s, with low mileage (which seems like a good thing, but depending on the bike and the owner, could be a bad thing, I've learned). Mine is an 86 with about 7700 miles on it when I got it. And I've put over 900 miles on it in the last 2 months.
We're also both musicians. I play piano and sing, and I played low brass instruments when I was a kid. Bass guitar is on my bucket list.
So, welcome! Enjoy it, and this is definitely the right place for information. I come here nearly every day.
