Hi all Is there one of these available for the CB1100? If not does anyone know if the BMW one would fit the Honda? (most likely different thread/hole size)

Good question, and nice find MC.
The tamper-resistant filler cap is also good lookin'.

They look nice. They are just a torx though- tamper ones would have a nub in the center.
I'd suggest silver as the anodizing would mar where the tool rubs.

Looks nice, but is oil tampering a thing?

If someone has a BMW that these fit, it would be easy enough to see if they fit the CB1100 before you order any.

... probably easier to quickly punch a gashing hole in the side of the engine case.

If I recall, the BMW has a larger diameter hole than we do. My old R1200R had a factory tamper-proof oil cap. It had a funky triangular shape to it, which required a supplied tool to open.

My 2004 BMW R1150RT has a completely different cap. It is all plastic, but is not threaded at all. Inside is a plastic T which fits into a slot inside the case. Nothing threads into anything.

How about tamper-proof valve stems? Or tamper-proof throttle cables? Or spark plug caps? Axle bolts? Rubber hoses? Bleeder screws? There are too many exposed components on a motorbike to worry about that could be tampered with that would leave you stranded, or dead.
Sobering thought.
