Anyone know the stock sprocket sizes front and rear for a 03rm125 and also what would you guys suggest to run for a little more low end? Currently running 13/49 which was how I bought it.

Try running 13/51 that should make it a lot snappier
Thanks! Going to pick up a sprocket and chain today. Yesterday was my first time riding it and the chain and sprocket were in decent shape so I figured I’d try that gearing before buying new, but it definitely needs to be done.

For future reference, 12/49 gearing is stock. 13/51 will be slightly taller.

I never torque them just tighten them and the spring pressure helps also

87 inch pounds. Make sure you torque them in a star pattern so the pressure plate sits evenly. Always torque engine parts, you're smart to ask that and not just go by feel.

If you are going to use a torque wrench, please use an 1/4 inch drive.

Mainly because the torque spec is very low for the majority of 3/8 drives. Ideally you want middle of the road and majority of dirt bike fasteners are pretty low. There have been many bolts snapped with 3/8 in the low range. If that is the only wrench available, go easy. I rarely use a torque wrench on those clutch bolts as all you need to do is bottom the bolt and no more. My experience anyway.

Makes sense for the clutch spring bolts. Yes I have snapped one just snugging it up.
