A couple pieces of information that covers several areas. First for all of those who have asked the new high mount Ti akra system on the SSP300 is not and will not be offered as a KTM powerparts exhaust system, in the near future. There is limited quantity for the SSP kits being sold and only customers that have purchased the kit can purchase them as spares. For now that is, it might become available sometime. They will have to develop a map for it too. The only map for it is the one in the SSP kit ecu for racetrack only. Secondly the cylinder head has been redesigned in the coolant passage and bridge over exhaust port, to prevent gasket failure. I just checked the parts fiche to verify and was told they did not change the P/N. The P/N on the '18 rc390r fiche is the same as first generation. They were supposed to start installing them in production. I do not know and doubt any are available here yet. The new ''revised" head will fit/interchange to first gen engines/cylinders. There should be an obvious visual difference in them to determine it. I will keep you informed as I know or when I see one.
