When I had K60's on I went out with my Son on his ZX6 and we did the big boys and their toys thing.
He commented later that I was certifiable, and that he was positive the BMW was going as fast as it would go.
All bragging aside, it was going as fast as it would go.
The K60 are not sticky, but they are predictable. They work reasonably well for dirt roads and light/moderate fire trails.
They last well when 2 up and loaded.
I might add, I also did this with an E09 rear, and D952 full knobby front. Flat out, skate through the sweepers.
Still predIctable, but....living on the edge.
