Vespa GTS vs Piaggio Beverly

Hello, I need your experience. Would like to get a stronger scooter to drive to work. I’m driving about 10 km of highway at the speed of 100. I noticed that the ride with the Yamaha Beluga 10 inch tires is quite wobbly. Since the adrenaline is already going up at 90 km/h in the curve. My favorite would be a Vespa GTS 300. Now I have to remember that the ride with the small wheels is similarly uncertain at higher speeds, there would be a scooter like the Bev erly with the big wheels more meaningful? Best regards Stephan
