Will show you the effect of changing sprockets. On my ZX6 I went down one at the front which makes the gearing shorter, makes it feel more lively, gears are closer spaced and top speed is lowered.
On the busa I’ve got +1 at the front. It’s got so much torque that in normal riding I can’t tell the difference other than gears last a bit longer and fuel consumption improvement too.
None of this will damage the engine, just make it rev a bit higher or lower for the same road speed.
