primary drive

Has anyone ever replaced the primary drive on px 125 disc.
I have a 177 kit and want to upgrade my P drive.In the sip shop you can find these.Do they fit a px millenium?

Many Thanx Curare.Should I also put other plates and springs in it?

hello balmo,

no, you can’t fit this to a millenium.

to upgear the millenium primary you need either this: art:87470000
or the longest you can go without changing the christmas three is art:93045000
the last one for the moment comes only complete with the renforced clutch.

If you have a Polini or Pinasco I would go for the last option (22 teeth), if you have a DR or a Malossi I would choose the first (21 teeth).
