havent riden on 190, as mine was fitted with 180. Noticed from Cads that I did seem to be right on, or over, the edge of wear when I returned to paddock. I am sure I had loads to go before disaster but it makes you think - how far can a 180 go? Also, Nick had a 190 and has strips on the sides, and we all saw how quick he was thru the bends and his pics demonstrate serious lean angle.
