IMHO the Heidenau K 60 Scouts are the best allround tire I've used.
Good enough grip in the dirt, nice on the road two up at 100 mph.
Without a doubt the best mileage I've gotten by far.
I've run a set of Mefo's to Alaska, two up fully loaded 990 and
while their mileage was ok, I'm getting 2,000 more miles out of the rears.
Around 7,000 miles.
For comparison I could never get more than 4,000 out of the TKC 80
Went through a couple of sets of K60's this year and have a new set
mounted on the 990 for a ride in South America ( shipping out on
Monday ) got a spare set in the shipping container.
On the pavement I'm pretty aggressive trail braking in the twisties
and the K 60's work as well as can be expected from a 21" front.
No weird squirming around while tipping it in on the brakes.
Da oggi la strada
é senza limiti
