Fiona Posted February 1, 2006 Share Posted February 1, 2006 Can't find anything using the search but I was reading this somewhere last night in a drunken state but can't find it again... But basically it was a bird fitted with a 900RR shock and upgraded race tech spring. Has anyone heard this? Any benefit/drawback? Any areas of concern to note? What I remember reading was that the shock length/height was identical between the RR and the XX so it was a direct swap and that by upgrading the spring you'll have a fully adjustable rear suspension. Hell, could have been the drugs talking and I didn't read it at all but I thought I'd put it out there and see if there was anything to it.

airborneXX Posted February 1, 2006 Share Posted February 1, 2006 Yep I read a few of them. Even bought one off Ebay for 20 bucks with 8,000 miles on it. Now to just find a spring... oh and money :wink: Quote Link to comment Share on other sites More sharing options...

Now to just find a spring... oh and money :wink: Have any of them to reference? I suspect it's not in the same class as putting a Wilbur's or Ohlin's on your bike but any idea how the two/three compare? Quote Link to comment Share on other sites More sharing options...

Otherwise how does the ride feel with your setup over stock? Quote Link to comment Share on other sites More sharing options...

HERBXX Posted February 4, 2006 Share Posted February 4, 2006 The shock can handle the extra weight of the XX no problem? Otherwise how does the ride feel with your setup over stock? I think a f4 and 929 weight close to the same . The shaft and the shock valve body(piston) seem to be identical, though the shims stacks are quite different. I have a 1100 lb spring and i revalved the shock my self. It's valving is close to he stock XX stack with allowances for the heavier spring. The ride is stiffer then stock, feels better , a little more controlled. Just putting in fresh oil can totally change the feel of the shock. I going to take some more compression damping out of the valving if i get a chance before spring. I'm thinking of trying more of a two stage compression stack but im not sure i want to deal with the complication. I just may remove one more shim from the valve face and give it a try. My xx shock wasn't worn out when i took it off. I was able to buy 3 f4i shocks for about 20 buck each off ebay last year. I have one as complete spare, one on my bike and one i nicked the air bladder on (losts of good parts left though) . You can't even by a new seal head for a shock for 20 bucks. I not claiming its better then a ohlins or penski or anything but i like it. YOu can still find almost mew f4i shocks around. The 900r shock are getting pretty old. If you use a 900rr shock it should be revalved and have the oil changed anyway. Quote Link to comment Share on other sites More sharing options...
