Well , I had thought about the differences , and the main issue was the 18" rear wheel , the tire selection is limited , and mainly designed for off road (AT 81 , etc.) , so there are no real "MX" tires in the 18" platform , since I ride a lot of tracks , AND , already have the 450X for off road , I felt I would be better off getting the R , I really did not want the stiffness of it , but , I can fix that ..... and I have a extra set of wheels off my 02 (Tusk Impact) that I built recently as you may recall , so I figured I could get a front and rear hub for the 20 , a front rotor , and have 2 complete sets of wheels for whatever terrain I ride , since the hubs are the only difference with the exception of th larger front rotor ..... Though I could have set them up for the RX , I did not want the larger tank when I did ride track .....
Since I am at the track pretty much every weekend I am not injured ,I just figured the R would suit me better in the end .... and I will always have the old reliable X for anything else ..... and the fact that I am really competitive , my friends are constantly telling me "Slow Down Roczen !" ... lol ... I wish I was as fast as him ... I would be heading to the Nationals to break in my new bike ... ,so again , the R on a track is where I get my adrenaline needs .... , and slow mountain riding when I get the chances , is just relaxing and a change of pace and the X does that very well ......
If I can't get my leg over the bike with my decrepit hips , I can always add the kickstand to the R .... but I am hoping I get a little more limbered up riding this thing ( maiden voyage is tomorrow .... hopefully I don't sink) , and that was one of the main reasons for considering the RX (that and the plusher suspension) , but the kickstand was really the main focus , but then the rear wheel started taking away that focus , so as long as I can get on/off the R without a stand , I will , then , if needed I can just add it ,and be good to go ....

...................... Besides ........... This is what keeps me thinking I am young ......... well ... till I fall ... then I wonder why I put myself thru this .... then I get dumb again , and go back to riding like I am 16 ... at least for a few minutes ...
