New HPSD owner here. I like mine so far (only 0.5 hrs on the bike). I had no twitchiness or "lock-to-lock" handlebar swapouts like I would get once in a while on the YZ450. On the stand, I can feel it work. Also, from what I've read, the 09 is a bit more responsive to tuning the clicker than the 08? And, in the manual, they give inspection and rebuild instructions, and time intervals, I'm sure, although I don't remember the specifics.

Overall, after years of ridng blue, I think this is a great little gadget that takes any twitch out of that wonderful Honda steering. So far...
