You mentioned doing something to your tank hoses underneath. Not sure of your climate in Greece (ours is hot and dry until Winter), but I had a buddy pull his new Kawasaki into his garage after a ride. The next morning he came out to a dented tank. Paint was perfect. He was looking all over trying to find what fell on his bike. Come to find out, Kawasaki had a tank vetn recall. As the tank cooled, the vent didn't klet air back in. POINK!It was already in my list to buy. Looks interesting and fits the looks, but it seemed a bit flimsy. My tank unfortunately got dented while I was at work. I don't know how or who did it but I used this simple sticker to cover the damage. I got it from a local bike shop.
The brand is One Design, it's the universal Gray
