• how to get the teeth (grooves) of the belts

  • I’m after some color belts for my ’94 YZ10 runner. but didn’t know the teeth of the front belt. so………. I counted it myself.
    it had 170 teeth on it. but I needed to make sure. it could be 169 or 171 if I made a mistake. so I checked the length. it’s a circle you know, so I had to fold it, and got 254mm length. but this still could be wrong ‘cuase the belt is not a thin paper. the actual length should be longer than 254mm

    254 x2 = belt length = 508
    we know the pitch is 3mm
    508/3 = 169.333333333

    so I tried 255mm
    255 x 2 = 510
    510/3 = 170

    then got a conclusion 510mm is the right length. but this turned to a bad joke. there was already 510 written on the belt

    510 3M 3.5
    length 510mm
    pitch 3mm
    width 3.5mm

    the answer was right in front of me. but didn’t know it before my hard labor. rear belt is 64T btw
