I brought this Biketek filler cap recently off ebay basically because I was interested and it was cheap. It was advertised as from a 600SS, but I've since found it can't be. It's 114mm OD instead of the 105mm that all the older Ducati ones I have are. It's got 201 marked on the back, but I can't find a reference to that online. The mounting bolt spacing is very similar but a just a slightly bigger PCD, and it has the 2 dummy bolts like an SS/Monster one. Does anyone have any idea what it could be off so I can put it back on Ebay?
Looks very similar to one I had on a Triumph 675 Daytona. If so should also fit the Street Triple 675. EDIT. Just checked a photo and it’s different. Sorry.
