I am researching what the RPM coming from the gearbox Tachometer drive at 10km will indicate what speed on the Tacho dial plate?.

I'm not exactly sure what

I'm not exactly sure what information you are looking for, but here is the math (I think) for my R6 with sidecar rear drive for 10k/hr:

10,000 m/hr
166.67 m/min
2.1 79.37 Wheel RPM
4.63 367.46 Shaft RPM
0.53 194.75 Speedo Cable RPM
3.6 1,322 Engine RPM (1st Gear)
