I am a little confused by this answer given by Motocross Action Mag.
Q: DO I STILL NEED TO ADD A TOOTH TO THE REAR SPROCKET?A: In stock trim, everyone loved how long each gear pulled, but worried about the amount of clutch needed to get out of corners in second gear. Going to a 49-tooth rear sprocket shortened the pull in every gear, but makes carrying second gear through the corners much easier. It also made third gear more usable. We have geared every YZ125 since 1996 down one tooth—we’re not going to stop now.
I read on the Renthal site that the stock sprocket is 49. Are they saying that they go to a 48 tooth.
I apologise for my stupidity and thank you for your help :thumb:
