I have the same situation with you, but a bit different. My
spocket size is 40 and tyre size 120, speed at 100km/h with 6k
rpm.
When I changed to tyre size 110 (same brand with you), spocket size
40, my speed at 100km is 6.5k rpm. I had a top speed loss of
10km/h. I think you had a better situation then mine. When I want
to go 120km/h, I need a rpm of 8k. Since I cannot ta han the petrol
usage like this, I changed to a smaller spocket of size 38. Then
things got better, 100km/h at 6.2k rpm, 120km/h at 7.5k rpm. So I
think itz the size of your tyre and spocket that makes the change.
If I'm wrong please correct me guys. I also dunno why I get speed
loss changing to a smaller size tyre...
