What's the pressure rating? It's not listed anywhere that I could find.

Well I haven't tested it but it has the 1.2 stamped on top and looks and feels identical. I suspect it's the same part. "
"This OEM BMW radiator cap is a direct replacement for the 1.2 bar Rotax 912 part at less than half the price."

Okay, then. That sounds awesome! Rotax is asking like $80 for their cap? Now we just need an alternate source for Ignition boxes!
(I cheated and built my own expansion tank with a "normal" $3, 16 psi [1.1 bar] cap.)
Thanks for posting as I need a New cap and would rather pay BMW prices than visit the local roTAX department
A new cap is on order
Even BMW discribe it as an oddball it is for a f650 bike
What year?
Sorry cant remember the exact year,but must have been early 90's as i remember thinking thats about when the 912 first surfaced
Found another cap you may want to consider. Used by KTM, Husqvarna, and Husaberg bikes. Part #77335016000
KTM bike cap only 18Cdn Warning this is a 1.8 bar cap so your engine could get a little hotter before it opens the cap. The website says your boiling temperature will increase because of the higher pressure.
This cap was easy to get. The BMW cap was $60 cdn and had to be ordered.
1.8 bar = 26PSI
1.1 bar = 16PSI
26 psi is really high. At nearly twice the pressure you might risk blowing off hoses.
