Before anyone can answer that question accurately, most will probably want to know how aggressively do
you ride, do you ride in rain, etc.
If you ride moderately, mostly around town, no silly lean angles.. and some racer-boy-wannabe who
grinds his knee caps on every curve recommends a tire.. and you wear it out in the middle after only
2000km, you'd think his recommendation was at fault.. but it wasn't
You might wanna be a bit more specific.
That said, I've been looking at reviews for scooter tires for years now, and I've had the same
size tires on my previous scooter and it's rather hard to find a negative review on ANY brand-name
tire. So, if you fall into the 'moderate rider' category, you'd be happy with any of the standard
Michelin/Pirelli/Dunlop etc, maybe even some of the 'no-name' stuff from IRC, Maxxis/CST or Shinko.
I seriously doubt you can get worse then the stock/oem CST tires, and they're just fine when new too.
