Welcome Jeff!
We have reversed roles, I cycled for years (since the 1980's), but when I turned 40 I wanted to do something I never did before and bought a 2009 Kawasaki 650R with 400 miles on it . . . the whole front end had been in a front end collision. I wanted to not only learn how to ride motorcycles for the first time, but learn how they work and to be able to repair them. It was a nice change of pace to have a mechanical motor in the frame and not be the motor for a change! Rode 44,000 miles on that green bike the first 2 years.
Glad you got back into cycling. If you can't find studded tires, my friends and I used to make our own studded tires when we rode our mtn. bikes in the winter time in Iowa. Get a set of tires that are worn down or slicks, drill holes in a pattern in the tires, feed small and short machine screws with button heads from the inside of the tires, poke them through the tires and tighten a nut on the screw on the outside. Worked great on frozen creeks!
