Malossi has a new Maxi Fly clutch. We got the first one shipped to the US and put it in about a month ago, and it's a lot better at take-off than the stock one. When we switched out the Variator and belt, the Clutch Bell was blued, and the stock clutch was shuddering on take-off. The Malossi Clutch is definitely a good replacement for the stock clutch and well worth $80. It's part M5217088 or 5217088B. If only there was a good sport level aftermarket bell that didn't cost an arm and a leg. I've been trying without success to get someone from Italy to ship me a Polini Bell while they are still out there. The CIF bell is a good replacement for the stock one, but doesn't offer any improvements, from what I can tell.
