I agree, stock fg mt tires aren't good for much other than parking lots bashing. even the cloned firehammer tires were better since they cut pieces out to make it more like lugs (siping?).
give a review on the insulator, never tried one so have no clue. I sold my last street bike in 1988 and the person that bought it, loaned it out and they wiped it into a park bench and the girl on back died. I was being sued for 3.5 million bucks, but lucked out finding a piece of paper a year later to prove I had sold it. I'd love to have bike again for cruising, but trips along country roads and such are way more laid back. too many idots in the city to ride around
