Just wondering if anyone could point me to, or has seen, a comparison of the final gear ratios in each gear for the new '08 GS vs the previous R12GS's?
I see BMW has lowered (raised numericaly) the FD from 2.8 to 2.9. But they also mention changing some of the gear ratios in the transmission. I'm most interested in how first and sixth would compare?

Thanks, if I'm doing this right it appears both first and sixth are slightly lower.

2007 GS final drive 2.82, primary 1.823= 5.14 reduction
1st gear 2.28 (5.14)=1-11.72
6th .81 (5.14)=1- 4.16

2008 GS final drive 2.91, primary 1.737= 5.05 reduction
1st gear 2.375 (5.3) =1-11.99
6th .848 (5.3) =1- 4.28
