Racing in Upstate NY, CSBK

Moto America Pros are way faster then CSBK Pro riders, except for maybe for 2-3 SBK riders.

Amateur level though, I find the CSBK is a bit faster then the club level amateurs (CCS anyway, since it's the only series I've done in 3 locations those far: NJMP, Daytona and Homestead)

I know as a Pro level Canadian, I must ride in Expert level in the USA but doesn't mean that'll be case for you here. Don't know how they classify you but I'm sure after a trackday/practice day, they and you will have an idea where you'd be running.

If you do decide to run a one off event at the CSBK level, be prepared to pay a full licence even if you're doing a one off. Effen CSBK/Pro 6 charged these past 2 years full licences for a one off event, which was never the case prior.
Anyway, Bridgestones will be the new tire provider for 2023, so that might change, as I think that Pro6 where the ones to mandate the full price of a CSBK licence for a one off event.

If you have anymore questions, don't be shy, I'll answer to the best of my knowledge or get you in the touch with the right people
