I have been ripping my proma circuits for a while now and I do love them. I wear ear plugs when I ride anyhow and I definitely enjoy the sound, but I'm wondering if anyone ever gets anything with a bit lower tone to it? Thinking more like Derbi Variant with a phat chamber pipe type sound. Is that impossible on a vespa period?
I'm tired of being the one with the most ring ring riiiiiingggggg moped at the rides. How's the calibrata sound?
