You want a bigger laugh go on an OEM parts finder website and look at the tires. A touch over $100 per tire. *gag*
Granted, I'm sure the KD1s would cost $250/wheel if they had an official Kawi P/N. -_-
Since Greg mentioned weight, that's the Kendas' weak spot. Cheap, Sticky, Light... Pick two.
Let us know how you get on with the KD1s.
