My suggestion is…
If you can wiggle your way into BRC, do it now. It’s not going to be any easier in the spring. (Motorcycles Ohio has an online registration system, and it was literally damn near full state-wide within a few days of the new season going live.)
Personally, I think getting it out of the way is key.
During the winter, you could strike an easy trade with someone for your snowmobile for a bike. Or find a bike cheap, because who buys bikes in the winter when it’s cold anyway?
I know I missed out on a deal of the century on a Ninja 650 someone had up for sale on Craigslist. The kid needed money and kept dropping the price every day. I hadn’t taken BRC, never rode before, and sure as heck didn’t have any clue how to get it home.
