RodeRash Posted July 17, 2003 Share Posted July 17, 2003 Does anyone know what the linkage rates are on the BlackBird? IE: How far does the shock compress when you compress the rear wheel 100 mm? Quote Link to comment Share on other sites More sharing options...
AlphaBird Posted July 17, 2003 Share Posted July 17, 2003 Does anyone know what the linkage rates are on the BlackBird?IE: How far does the shock compress when you compress the rear wheel 100 mm? Approx 2:1----raise the shock height 1mm---get 2mm intherear Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted July 18, 2003 Share Posted July 18, 2003 I thought it was a riseing rate linkage. That way it moves easy for small bumps but has more resistence for big bumps. Quote Link to comment Share on other sites More sharing options...
SwampNut Posted July 18, 2003 Share Posted July 18, 2003 What you describe would be low-speed and high-speed valving on a shock. A rising-rate linkage decreases the leverage as the suspension compresses, effectively increasing the spring rate as applied at the wheel. This gives a softer ride at normal compression, and helps resist bottoming by raising the rate. I doubt that the XX has rising-rate linkage, but I don't know. Sport bikes avoid this, same reason they avoid progressive/multi-rate springs. Quote Link to comment Share on other sites More sharing options...

This is correct--All Hondas have rising rate linkage--its how they pass their own two-up off a curb scenario---on the 929 I actually got rid of this via an imitation HRC dogbone/plates from DK---it eliviates the power-on squat that the rising rate produces under heavy track acceleration---makes the travel/spring rate alot more linear Quote Link to comment Share on other sites More sharing options...
