It was finally time to get some new tires, after 7000 Kms for me, and 4000 Kms for Chris. This is what I saw after removing mine... Almost! I got me some Michelin Pilot Sport, Chris got Metzeler 7 Teen. The only problem is that the Metzelers are rated for 120 Km/h, the Michelin ones are rated at 150 Km/h, like the originals, and as Piaggio suggests. I need the higher rating more than he does, as I use the freeway daily, going at top speed. At 130 (real) Km/h, 143 indicated, where the rev limiter cuts off (constantly). Both sets work much better than the OEM Savas.
