For Aprilia RS660 ('20+ models)

Diamond quick release tank caps have been used and trusted by many of the worlds top teams for well over a decade. Precision milled from lightweight 7075 aluminium to the exact size of your bike's tank cap recess - making for a perfect, flush fit. The beauty of the engineering is highlighted throughout by the flawless deep black hard anodising.

Diamond's Posi-Lock, spring loaded bayonet centre cap makes for quick release for re-filling, but with a positive solid locking mechanism to eradicate centre cap loss. 

Every Diamond tank cap is equipped with it's own internal breather line, to equalise vacuum pressure within the tank as your fuel level drops - So no fuel starvation issues.
