"The continental Zippy 1 is truly performance-enhancing equipment. I did not realize a tire could affect performance is such pronounced and profound ways. If you did not think the Vespa GTS could handle any better, then put a Continental Zippy 1 on the front and back and hit the twisties. Wow! The Zippy is a great performance tire. I was never impressed with the OEM Sava tires. With that as my reference point, I cannot over state how much better my GTS handles now that I have switched to Zippys. Great Tire, Super Service, and a Pro-Scooter atmosphere at Edwardsville Vespa. If you want to optimize the performance attributes of the GTS I recommend replacing the Sava tires with the Continental Zippy 1."
