Does what it says it does. Keep your fuel in your tank secure, especially with the reading gas prices.The key cover scratch the underside, but I can live with that for the price I bought it at.

Fit my bike perfect.

Cumple con su función.El modo de uso es lo enroscas como cualquier tapón sin llave, luego metes la llave y le das vuelta hasta que tope. de ese modo aunque el tapón gire ya no se abre y no puede sacarse.La pintura se ralla con facilidad incluso usando la misma tapita que trae incluída, es una lástima que sea un Drag Specialities y el “único” con llave, la calidad al tacto no me gustó mucho, pero por el precio está muy bien, de vista luce bien

Use it only when going on tour, fits well and does the job.

The only thing i didn’t like was that it had a decent chip in the key cover but all in all good cap
Big gut no butt –
On my 2022 streetglide, it would require some extra work modifications on my tank lid. Bought this keyed cap months ago. Haven’t put it on yet. Probably won’t.
