Retractable Pop Up Fuel Cap for Triumph Rocket III

These neat little gas caps give a clean look to your tank and have the added benefit of being lower profile than the standard fuel cap making them particularly suitable if you carry a tank bag on occasions. They are also super easy to fit, they replace the original fuel cap without any modification to the old cap or tank.

The replacement petrol caps are well made in Aluminium and are available in a chrome or black anodized finish. The mechanism works smoothly, just press down on the centre and turn 90 degrees to release the knurled inner and simply screw the cap off or on as usual. Pop the inner back down and turn back through 90 degrees to keep it down out of the way. Have a look at the video below if we've managed to baffle you!
