I'm going to be purchasing and rebuilding a vintage Vespa, haven't decided on a year/model yet, but what I want to do is really set it apart with the metal work, giving it a great steampunk appeal with copper and brass, but my concern is mainly with the strength and longevity of these metals on a Vespa. I want to to the trim and accents in copper and the breaks, kickstart lever and switches in brass.
Is brass going to be too soft for a kickstart lever? And will I need to worry about the weight of these metals? As far as tarnishing is concerned I know there are metal lacquers I can obtain so that I'm not too concerned about.
