Tamper proof oil filler cap

[GoldOxide_imp]

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.

I reckon a tamper resistant oil cap is for those who might need to leave their poor ol' CB parked in the dubious part of town overnight and wish to minimize the opportunity of some punks pouring sand and gravel into the crankcase.

Conceptually very easy to do with maximum impact.
