From memory, the stock tires were greasy feeling ( like any new tire ) for first 100 miles. At 300 miles ( got bike new out of state and ride 1000 miles), they felt pretty good. At 1000 miles, they started to go downhill. At around 4000 miles ( I really forget now) rear tires was bald, some steel belt was starting to peek out. The front had some wear left but had irregular wear pattern, looked awful. Virtually every mile on bike was just basic 70 mph slabbing.
Kawasaki must have gotten one hell of a deal on these tires as they still use them. I mean, how long have these tires been around? Twelve years? More? Mich seems to upgrade their tires every three years.
Anyhow, I thought that the c14 was a two wheel rolling turd before replacing those stock tires with Michelin’s . Now it’s like one one of those hippos in Fantasia - bike is fat and heavy, but she can now dance pretty good!
