The last couple times I have been out on the bike, I have noticed it handling a little stupid. I suspected the tire pressure, but with less than 400 miles on the bike, it couldn't be. Wrong, the front was about 7 and the rear was about 20. With it being so light, a low tire will not be obvious. Being a retired rural carrier, I am always eyeballing tires. You will not believe how many vehicles I see with a low tire.
