My Z250 has 17 inch IRC Road Winner tyres, front 110/70 and rear 140/70. A few weeks ago I was riding a nice new road .... with a bit of gravel (for about 10km) on it and that was very unpleasant riding. Quit a few times I could feel the rear or front sliding a bit in a curve. Never had that so much before (with my Kawasaki Versys with Pirelli MT60RScoras or Avon Distanzia tyres). I checked the tyre pressure and it seems OK. So although I am not yet in the need to replace the tyres I am a bot searching what is for sale in Thailand. The size seems a bit weird as there are not so much options that does not change the height of the bike too much. I liked the Avon Distanzia but I think the size is not really matching. So has anyone a good recommendation?
