There's no bike I like more than a K, and of the 3 I've had the current 1991 16v K100 is the winner.
HOWEVER!
It's no secret these have unique wear characteristics on the front wheel. As Johnny probably says "Thes just hows it wears a fronts tior". Bud Provin seems to agree. I'm at about 3000 miles on the current tire and it's almost at the wear bars - plenty of pressure, new fork seals, good head bearing, aligned well. 3000 seems very, very low for not a soft, sticky supersport rubber. And so I put it out to the community of you folks: if you mitigate front tire wear, how? What's your favorite tire to put on? And how many miles are you getting out of yours?
