I just installed a pair of Ricor Shock Imtimidators on a friends RK. They say that they reduce front end dive under braking and increase the response to bumps and irregularities from the front end. Pretty easy install, drain forks, remove spring, install spring, add ricor 5w fork oil. Bike did seem to have less dive and the ride was smooth over some bumpy road, but I haven't ridden a RK much so I don't have much history with it. Web site is http://www.ricorshocks.com--take a look an tell me if there worth the $298.00.
