Minarelli C2 Variator 19 High quality Polini 4 petalNew old stock, original variator for Minarelli C2 engines. If you're lucky enough to own a C2, you might want to stash one of these away for a rainy day. They are a hard to find piece and they can crack. We have had to replace a handful of these ourselves on bikes here. This is just the variator. This does NOT include the ramp plate or the back plate.
