Just looked at my dyno chart - it reaches max hp at about 9000 then it flattens and stays constant to 10000 and rolls off fairly gently after that, still showing about 100hp at 10700rpm where the curve stops. Moto Rapido have said to me that it's not really worth revving past 10k but I still hit the limiter sometimes when being over enthusiastic
Apologies to Tony H for hijacking his thread a bit..........
