They certainly didn't make the bike feel faster. The only thing I can say in the Kojak's favour is that these were light.

I persisted for a few weeks with the Kojaks, constantly repairing flats until while visiting a friend in a rural locale in Germany I gave up on them and replaced with some very cheap department store tyres which were clunky and nasty but better than the Kojaks because at least I wasn't fixing flats every several kilometers on average. But they were far from satisfying.
