I have these in my XS11 forks. I actually sent them to Race Tech and they did the treatment. The bike sure handles like a champ. I was also told by Race Tech that you really need to replace the rear shocks because they work together and have a large impact on how the bike handles. I guess, most folks just do the forks and leave the rears stock. So, I bought some progressive rears.
Here in Cali, I the big problem we are having is texting while driving. I see it regularly when I look out my car window into other cars. I was rear ended by a teenage texter. My assistant was rear ended by a car that was rear ended by a texter. Teenage drivers are bad enough drivers, then you distract them with mobile phones.
