Mounting
Excellent tires for the klx300. They are a bitch to mount the rimlock. I had to get the tires to almost 90psi to set the beadlock right otherwise they are nice.

Top notch everything.
Arrived 1 day sooner than promised, top tier tires are excellent. Bought both front and rear and both tires have recent manufacture dates, a big deal as last time I ordered from Cycle Gear Chain and the rear was 3 years old.
