Say for example a 125cc motorcycle with 6 gears has a top speed of about 75mph, why can’t they make it with 7 gears and surely that’d increase the top speed?
In: 1
Gears don’t add more speed. The engine has a certain amount of force it’s putting out, and that force is what determines speed.
The function of gears is that combustion engines have to spin between a certain minimum RPM to prevent stalling, and a certain maximum RPM to prevent damage.
