1200 Enduro Secure Oil Filler Cap

Conquest Carbon; my Ducabike Ducati Engine Oil Plug Cap £17+p&p has either a HX6/HX8 bit recessed into the cap. So you'd need a tool to get it open. I've had a locking key one on my beemer but reverted back to a normal one.

 

I bought this one for my non DVT and then put it on the DVT. Second hand on fleabay for £10.

 

No idea of the cost of theses things, but It goes in the hole where the oil goes in!
