Custom hand lathed from aviation grade billet 6061t aluminium. This sale is for the complete new cap fully assembled and ready to fit on your bike.
Sides of the top cap have been knurled for extra grip – the lower threaded part of the cap in aluminium has a spring bound valve system centrally located in the middle of the bung. This connects to 3 vents in the top part of the cap to allow alleviation of any pressure that may build up inside the tank. It also comes with a petrol-resistant o-ring seal that sits on the top of the thread.
We spun three concentric circles on the top of the cap using the lathe with the centre part higher than the outer.
This listing is for the POLISHED ALUMINIUM TOP/ALUMINIUM THREAD assembly of the tank cap.
Some models it will fit include Bonneville, T100, America, Speedmaster, Thruxton. It will also fit on the HD Sportster and probably a load of other models.
