I have no idea what is the part number of the triple clamp. I can't see it. It what it is.
I just put on a brand new 170 tire. I guess I'll just wait another year or so and experiment with a 160 By your theory, the more mileage on the tire, wearing down the center, the bike should be more stable?
In the meantime, the rear shock is set to stiff and I keep the rear tire aired up. I might think about softening the front. It's just much worse with the big HB jrs on there. I really noticed it when I had the shop put on new front tire and they aired it really stiff (like 40lb) and the bike was weaving & bouncing all over the road. I usually keep the rear about 4-5 lb heavier (40 vs 36lb), I might up the difference (maybe 42 to 34).
