The tire, if you just want to break your bike, not of course on dirt but on Greek goat paths, is just what you need.
It bangs at the slightest bump, the tire carcass is made from concrete and steel.
Also, it's the best way to break your back in two, and that's not an exaggeration at all, believe me, you won't miss out.
I wouldn't recommend them to anyone, regardless of the fact that they have a sporty crown, maybe the only positive.

I put the tires on a 250 cc scooter and after 14 months and 4000 km the tires were ready to be thrown away. The tire dealer I asked for an opinion said that Pirelli states that these specific tires reach the end of their life at 6000 km. Wasted money since when I put them on, he didn't mention anything like that. I wouldn't choose them; very disappointed.

the worst, it slips for fun and is extremely hard, you fall into a pothole and think that the scooter will break, stay away, citygrip all the way

Terrible black tires on the Forza 750.. Such a waste of money.. On the streets of Athens where the road markings and asphalt quality are mediocre, the rear tire slips for fun.. I find it hard to believe that the old tire, which had 14K kilometers, held up better..

In Kymco Xciting 400i, I put these - admittedly worn after 3.5 years - their cousins Metzeler Fell Free. Big difference in grip in all conditions, no more worrying slips front - rear. It's like I changed my bike. Also, faster response, so it feels lighter. It's also about 10-15% more comfortable, something that used to bother me a lot on my scooter.. now it's bearable. Very satisfied.
