I sure agree that the K60 scout's performance is sometimes questionable.
I have run Big Blocks and just loved them, better on the road and a real knobby off road, the rear is junk in 3,000 miles though.
I run K60s only because they are the best compromise I have found,,,,, I'm still looking and waiting for tire companys to get the ball rolling on big adventure size tires.
As far as I'm concerned all them stock type tires are a joke for this kind of bike [dangerous offroad]
Why buying this type of bike and having street tires on it------you might as well be riding a Harley
