I put them on my 02 ER model last year. DO IT!!! You will never regret the expense. Just a quick click or two and you can adjust for conditions. I have rebound and compression adjustables and am VERY happy with them. You can pound through the stutter bumps and not have your arms and shoulders beat up. Just gotta get a new center and rebuild my "used" rear Ohlins shock, and it will be perfect.
i put 2 new ohlins clickers on the front and the big one in the rear (comp. adj. only), and had my center rebuilt/revalved by pioneer- trying to save a few bucks. havn't tried it yet-- i'm hoping it'll be a good setup.
