I went with the 30T on my 08 SERK. With the gearing on that model, I did not feel 30T would be enough difference. I have been very pleased with this mod. Great low end launch & 6th gear is much more usable @ highway speeds.

The stock gearing on the 11 SESG is much better, I do not feel a need to make any changes.  FWIW.

What, if any, changes to dyno numbers when changing to the 30 tooth gear?

I'm thinking the rpms should change by around 6% since that equates to the gearing change.

No.. gearing won't change HP or Torque figures on a Dyno, as RPM is factored into the equation...
i.e. the Dyno will account for the change in RPM as well as the change in torque and the resulting readings won't change.

It will directly affect torque applied to the rear tyre at any given speed and RPM though.

Does anyone have a good source for these gears ?
Are you buying them from Baker ?
I'd like to try a 31T on my Springer.
