Hi Jack,
Boy, I bet that greeting will raise some eyebrows in the national security circles.
I can't stand my own fat rear tire. My last replacement was with a size smaller which made my BA handle a lot better in the twisties. I am following "piper" with getting a larger front tire soon. He did it to get whitewalls I think, but I want it for handling. I am a flattracker at heart, but love the way I sit in my BA. That's a trade off, I know but all my old well handling bikes had equal or near equal size tires. Most winning flat trackers actually have larger front tires.
What am I talking about? I am 51 years old and thinking about draggin a knee!!!
I guess the fatter back tire lifts the rear of the bike up enough in a corner to enable you to turn your head to watch the sparks flying off your bike. A fatter rear tire surely will not last any longer. I hated throwing away my rear tire with 50,000 miles of tread left on the sides.
