I guess I'm one of those guys. 03 HD with only 8K miles. I will say that she has never been on a trailer to a rally. I work a lot and cannot use my bike for work because of the amount of stuff I carry for work. Believe me, with the cost of fuel today I WISH I could use my bike for work. The tires on my Deuce only have 8 K miles but they are 6 years old and I have noticed some cracks in the side walls. Are some cracks OK or should I immediately replace them ?
