Does anybody know if nsr500 has any part in common with her sisters?

I mean, front and rear sprockets are shared with rs250 mono arm? Or maybe rc30?
What about the clutch discs?
And the pistons, pins, rings and clips.... What about honda cr250?

Keeping the distances, I've had a '00 tz250 that can be fitted with vertex Suzuki rm 250 pistons, just a skirt 5 min modification needed et voila you have forged pistons instead the weak standard equipment...

Thanks you all.

Every time I stare at this bike I know it's been a good choice!
