Monza Fuel Cap


The Monza Fuel Cap has a long history dating as far back to the 1930's. In the 1960's, this fuel cap became a staple on British sports cars and race bikes. These faithful reproductions manage to capture the look and feel of the original chrome caps for less money and much higher quality than what's currently being produced by the original manufacturer.
