Hello Italy, it is possible to mount the new Grimeca NT kit on a PK Fork Rush..... It is the same procedure like the PX Millenium Kit, including the 3mm displacement (i guess it has been the same with the Grimeca Classic, but you won´t notice). Also it is possible to mount a RS24. I would recommend the S&S version, because this one is 18mm shorter, I am a link. It is usefull to have the shorter version, because the PK fork is 35mm longer compared to the original fork (dragster look). Some GSF users tested the RS24 in the european scooter challange and it can be recommended. Hope i could help AL
