so i rode all the way up to Arctic circle and coldfoot.. with my cbr600rr, that was with touring tires, arriving at Arctic circle. met all the GS guys, and ooh no "you aint going to make it up to the top with those tires" then i got some chills and decided i should wait till i find some knobby tires, went into Ak leather and they showed me the continental Tk, i think these are going to do the trick for next year! yeeeHAAA my tank can do maybe a good 130 miles to a tank, i carry a 1 gal jug, should i plan on getting more gas jug from the stretch from Coldfoot till Prudhoe ? to the top with these tires. what cha think??
