Tires/tire combination. After recent screw in rear tire, determined by me to be not repairable on maybe 2-3000 miles left on thread=new rear tire for me, this time Bridgestone Hoop, with Michelin Power Pure on front.
This combo seems to work ok. I bought Bridgestone as it was what local dealer had in stock. I know matched sets probably work better.
SilverWing once Bridgestone as OEM, my 2009 had them=worked ok. My 2013 leftover came with IRC=worked ok, I especially liked the IRC front, it lasting 25,000 miles and worked well with replacement rear Michelin Power Pure.
Now I am not worried with present Bridgestone on rear BUT in past have had Bridgestone Scooter tires fail ---one on Helix in Japan, 2 on Reflex in US. All thread related on rear, none caused me to go down, caught them before they could have flown apart But something to think about.
