Hi all, I have a bike that has top speed at 70 kmph in 5th gear, 4000 rpm. I feel like there is still more engine power left un-utilized. Now i wish to do some calc and add a 6th gear, so that top speed is pushed to 100 kmph. Please shed some light on this topic and help me do math and identify if its feasible or not.

You can use the relationship between the brake power, torque and angular speed. Once you decide the expected power output, then you can get the required torque that can give you 5000rpm speed. With that, you can go ahead and cut the gear based on the availability of gear design parameters.
