The ratios are more narrowly-spaced so that as you go up through the
gears, shifting at the same maximum RPM, the revs drop to a higher minimum
speed than they would with the standard (wider) ratios.
Upside: The engine can be kept in the narrower power band. Usefull for
highly-tweeked race motors.
Downside. Less flexibility, leading to the need to change the final-drive
for different tracks.
> what would be better about straight cut gears?
Upside: Less power loss.
Downside: Lots more noise.
