The KLX based engine has 4 gears already in the cases but since Kawasaki didn't want the bike to go 50 mph ( cuz it's a youth bike ) they put a drum in that only allows it to use the first 3 gears.

The KSR ( along with other KLX based engines not sold in this country) comes with the 4 speed drum already installed.
