Just a few words of warning about the Piaggio front rack, specifically on a 2023 GTS. The shoulder bolts used for installation are known to be made of ricottium alloy, that is, baked ricotta cheese.
I crashed on Day 3 of the 2025 Scooter Cannonball. I was on a dirt road with hard pan washboard. The ride was rough but manageable at 20 - 25 mph until the scooter suddenly started to shake violently, and the front pitched down to the right. At first I thought that I had just hit some kind of resonance that amplified the peaks of the washboard. I'm now thinking that the front rack contributed to the problem.
I had added a light bar to the rack, and was also carrying a full 1.25 gallon gas can on it. After the crash, I noticed that the lower shoulder bolt that the rack bolt attaches to had sheared off. This could have happened when I crashed. It could also have happened during the bouncy ride, and if so, then the rack would have become a 10 pound pendulum that swung the front end off course. I had broken one of these shoulder bolts during installation, so I know how soft the metal is. I did get replacements from Motovista. I know to blame the rider before the machine, but I'm putting this out there as a warning to watch that front rack under load.
