Even on my commute, I don’t really have need for a topcase or rear trunk. The Vespa GT comes with a rather sturdy rack mount on the rear, which is all good, but I certainly don’t need it. What’s more, that rack mount covers up the glorious sloping rear end on the GT. So I got the idea that if I swapped the underseat plastic bracket from a GTS, I could clean up the rear end and get more of that classic Vespa shape back on my bike. This was the result. I love it.
