    High-pressure radiator cap for RSV4

    My 2016 1/2 RSV4 RF has a 1.4 bar radiator cap. Does anyone know if there is a higher-pressure option available....?

    I am looking for 1.8-2.0 bar if available.

    Does higher pressure rating = higher boiling point??

    Yes, higher pressure means higher boiling point.

    Hello guys, did you get a solution. I am looking the same for my 2016 RSV4. Tried the Graves 2.0bar but it did not fit.

    Call AF1 to see the current spec on #893954. I got a 1.6 bar cap earlier, and I think this was the one. It made a small improvement.

    Something needs to be done. I use the additional super stock radiator and my bike still "lightly" boils over in the summer, which is all the time here in So Cal.

    1.4 is way too low for a hot V4 track machine. I constantly boil out into the tank and then I have air in my system making it worse.

    OK. Borrowed my buddy's radiator cap off his 2015 KTM 500 and it fits. The stock KTM cap is a 1.8.

    Or you can get a CV715-31mk off of Amazon. It is 2.0

    Anyone know if only the older KTM 1.8 bar (listed as small version) is the only one that fits or do the newer KTM/husky caps fit?
