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
