Hi Fade-Dude. I had one fitted to my 03 636 race bike. It worked, but I am not a great fan of it. Fitment required drilling for the dowel pins, and if it wasn't checked regularly it would loosen a little and the dowels would start making the holes oval. Another thing was that the damping rate between clicks are, excuse the pun, Extreme. Please do not adjust this damper while riding, because the difference between medium damping and solid hard happens in like 2 clicks. If you get it, fit it properly and change settings while stationary. I have a WP damper which is absolutely wonderfull, but hard to find and expensive. I have sold my 03 636 and bought a 06 636 to race with now.I am going to modify my WP mounting kit or look for another mounting kit that might work. I know that the Hyperpro dampers and damping kits are available here in the RSA and my damper will fit in their mounting kit. Linex Yamaha is the importers of Hyperpro and I have seen the mounting kit here in Cape Town. I am looking forward to getting my 06 on Friday.
Keep it mean and green!
