blackmax Posted June 13, 2008 Share Posted June 13, 2008 I bought a 900RR shock from a member last fall, planning on installing it tomorrow. Anyone have any experience with the stock spring? Will it be sufficient for a 190 # rider ? I ride solo 99% of the time. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Redbird Posted June 13, 2008 Share Posted June 13, 2008 I don't recall the exact rate, but it will be way too soft. That was a popular mod for awhile, most were going with the heaviest spring they could find to fit, which I believe was a 16kg/mm- still too soft unless you're on the lighter side (for an XX rider).

CxBXR Posted June 14, 2008 Share Posted June 14, 2008 Too soft that come from a bike that weighs almost 100lbs less. Quote Link to comment Share on other sites More sharing options...
Para045 Posted June 14, 2008 Share Posted June 14, 2008 From the Racetech site: 95 CBR 900RR Rider Weight: 190 lbs. REAR SHOCK SPRING Recommended Rear Shock Spring Rate for Street: 15.75 kg/mm (use closest available) Stock Shock Spring Rate: 14.6 kg/mm (stock) FRONT FORK SPRINGS Recommended Fork Spring Rate for Street: 0.857 kg/mm (use closest available) Stock Fork Spring Rate: .820 kg/mm (stock) CBR1100XX Rider Weight: 190 lbs. REAR SHOCK SPRING Recommended Rear Shock Spring Rate for Street: 17.25 kg/mm (use closest available) Stock Shock Spring Rate: 16.8 kg/mm (stock) FRONT FORK SPRINGS Recommended Fork Spring Rate for Street: 0.991 kg/mm (use closest available) Stock Fork Spring Rate: .890 kg/mm (stock) I have a 95 CBR 900RR shock on my 98 XX with an Eibach 1100lb (19.3 kg/mm) spring and with my sags set for my 300lb weight I am on the second lightest notch of preload and it feel quite good but put the missus on the back (~180lb) and I do notice the difference Quote Link to comment Share on other sites More sharing options...
blackmax Posted June 14, 2008 Author Share Posted June 14, 2008 Thanks, I haven't compared the shocks side by side, is it possible to put the stock XX spring on the 900 shock? Quote Link to comment Share on other sites More sharing options...
Para045 Posted June 14, 2008 Share Posted June 14, 2008 Thanks, I haven't compared the shocks side by side, is it possible to put the stock XX spring on the 900 shock? No the XX spring is quite a bit longer Quote Link to comment Share on other sites More sharing options...
