The 80GS and 80G/S Speedos - mono and para - are the same
R80GS & R80G/S MPH/KPH = W1244
3.36 (RATIO 37.11 SPEEDO 1.244)
The older Speedeos would have been expressed this as 1.244 rather than 1244

W773 = R80G/S and R80ST KPH only

W means 'Wegsteckenzahl' ('travel-distance-index-number'), which equals the number of rotations for 1Km and/or 1mile (a mile would need more W's) travel on the speedo - this is both for recorded mileage and speed

to answer your question - the speedo matches the rear drive ratio

Hope this helps
