hi all. can you folk tell me what speedo speed your XB does at say 3000rpm in top gear. just trying to see how different final drive ratio is between both bike's. Tam.

overall ratio: 4.7 (XB9) vs. 3.6 (XB12)
final ratio: 2.4
primary ratio: 1.6 (XB9) vs. 1.5 (XB12)

Or if you are sad like me;

XB9 = 4.03595 to 1 = 18.33mph/1000 = 55mph @ 3000.

XB12 = 3.6111 to 1 = 20.487mph/1000 = 61.5mph @ 3000.

Approximately!

guys exactly what I needed
