If you have tried to swap your fuel cap out from the stock "monza" on your Thruxton 1200/Speed Twin/Scrambler 1200 tank you will have found that you have been left with a strange notched ridge that is welded into the top of the tank.

Up until now your only choice was either ignore it or grind it off.

This sale is for the ring adapter piece only cnc machined out of 6061-t6 aluminium
