Does any slick tire manufacturer do an 80 series radial? My bike originally came with a 110/80 front and 130/80 rear bias ply. I've run every bias tire known to man and they suck compared to my Rosso 2 I've used for four years-a brilliant tire hot, cold or wet. My bike(s) love them. The pirellis however are 110/70 and 140/70 so I lost almost an inch of ground clearance upright, and because the radial profiles are more rounded, it gets worse as I lean over. I can't bring up my belypan anymore without setting it on fire from the exhaust lol! I need a bit of extra height so any input is appreciated. Thanks to all, be happy, racedays are coming!
