Does anyone know the thread pitch of the front sprocket nut?

Recommended Posts

Manual just says "M22" and leaves out the pitch : ///

(oem part # 90179-22018-00!)

So FZ-07 uses the standard pitch? Fine pitch is 1.5 or 2 mm --- but the manual doesn't even specify"fine" or "standard". For example the rear axle nut is actually a fine pitch -- but that's nowhere specified in the manual either!

Is this Bodystyle rear fender extension useful against mud everywhere after a short trip in the rain? I've installed the same last weekend...

But @topic.

The description of this Ebay offer for the nut with Yamaha Art.Nr. 90179-22018 says M22 x 1.0 :

Ok, maybe not the best source of information but the only one I found atm  😕

22 x 1.00  Appears to be the correct nut,  but missing the 2 small dimples at the outer edge, like the pic.

Rear hugger- Do not ride in rain or mud often, at best would keep mud off the shock.
