Technical SNR Rotax gearing PFI

[frenc1i]

Hello,
Going up to PFI for some testing next week in SNR Rotax, not sure about gearing, I've been told 12/79 but not sure if the 79 is a bit too high given the long straights. Anybody have any recommendation's pls?.
Ian.

Ethan's guide says 12/79 should do. Not sure if it has been updated since the bridge extension but you can always change at the circuit if need be. Just bring a couple sprockets and make sure they are all in good condition

Cheers Jacob,
Sounds like a plan. We’ll start with that, and drop it down a cog or two to compare.
