    This is a *Must Have* item and an absolute work of art that is extremely functional! Forget using the Key anymore….

    Never understood the lock, bike would be stolen before someone would steal fuel out of it. Total pain in the butt taking the key off the bike, opening the fuel cap, take key back out because it hits the steering stabilizer and won’t let cap open fully. Now put key somewhere, fill up, put key back in to close the cap and finally take key out of the cap and put back in ignition.
    OR, OR; buy the fuel cap adaptor, i would also buy the pre filter that goes on the cap, turn it to open. Fill up, turn to close and be off. Very well made, comes with everything you need to install in under 10 minutes. My mosko tank bag still fits nicely on top of the tank.
