Be careful, I recently had to replace 1st gear on my LI 150 S3 and contrary to all the evidence out there, I needed the 117.5mm one...

There's no guarantee that the badge on the front matches the installed box unless you know it's never been opened. You should always check all the gears and make sure that you've correctly identified the gearbox.
