All 2st Provini?

How can I get one? Or is it not worth it?

Thanks,
Josh

I had one and I say YES, it's a very good mod for the WR250 / 300. Problem is they are hard to get. I'd be the first thing I went after if I got another two stroke. You can get them direct

It would be nice if somebody would import them, but they are worth the trouble.

Is it a problem if I don't speak Italian to order direct? Any idea on the current cost? Thanks!

Send an email and get details, then go from there.

What does it do ?

Controls the rate at which the power valve opens and smooths the action. It's a damper unit / shock for the PV.
