This question has come up before, some felt a difference btwn a std/tourer and an I/S. I found an article that provides some info. Rider June '99, was about the I/S
Compared to the std/tourer.
I/S forks
1. spring rates are the same
2. compression damping increased slightly
3. Rebound decreased slightly.
I/S rear shocks
1. spring was stiffened, common knowledge
2. rebound rate was stiffened.
enjoy.
