    Which sprocket size do you recommend for Yamaha Yz 125 2001?
    Front and rear...
    Standard is 13t front and 48t rear. Some people are saying +2t rear.
    What do you think? What are you useing?

    What are you riding? MX or Woods or both? I went to a 13/50 and it was a good all around gearing ratio.

    I then went to a 13/52 for woods riding and wow what a difference. It allows the bike to lug more in the tight stuff and not stall as often.

    If you are riding strictly MX I would probably go with the 13/50.

    This was on a 2001 YZ125.

    Here's something else you may want to think about on the '01. Read the whole thread. It makes a difference and is cheap and easy to do if you have a manual.

    Get the spring if you do it. Don't bother with the spacers. It is the same amount of work and you have the factory part in there.

    Ok, thanks!

    So 13/50 is a good combination?
    I`m riding mostly in sand.
