I've replaced my red Koni Ds with Vikings (Biserker models)... very pleased with them.. especially the ease of quick adjustments by simply turning the knobs (Konis require, at least, partial removal and twisting them). I loved my Konis... but the new generation of double-adjustable shocks -- Viking, QA1, etc) have revolutionized shocks/dampers for those people interested in having more tunable rides. Of course, tire sizes, tire psi, suspension set-ups, etc... all further contribute to ride quality.
