My bike redlined with stock gearing only 3 times (indicated 171/2kph) and that was a long 3-5km downhill, most other times 169kph took some effort. TX_Dj and SS got similar (102mph on USA speedos @10500)Depends how much top speed you are willing to trade in order to get the fastest acceleration. Any given bike also depends on how much the power curve is falling away on the top end which is quite a bit on this bike unless you cut down the intake runner and fit a pod filter.
Now it redlines with 13t front on the flat or slight downhill provided there is nil wind and the temps are warmer than 30 degrees.
Before it would be back to 152kph uphill or into wind.
Now it keeps accelerating everywhere.
The 6% gearing change is more than offset by having the power to do a higher average topspeed anywhere.
But I doubt you'll understand, looking at torque graphs may work on paper dont always work in practice.. you need to be above the torque curve.
