There was a point in time when the Gilera Nexus was going to be the hot big bore racing scooter, and a lot of companies made race parts for it. Piaggio made it just about impossible to do a big bore cylinder kit for the engine when they punched it out to 490, and the racing world moved onto the T-Max. The Malossi cam was developed while the Nexus was very actively raced, along with a set of valve springs that are better suited for long stretches at high rpms, and should be installed along with the cam.
We have sold a few of them, mostly to Latin America, and my understanding is that it still sells well in France, so you might get feedback from actual users on forums there.
