I just got mine the week before Thanksgiving and the firsts for me was full skids and a bumper. I guess it really depends on your riding locations. I do trails in Ocotillo Wells in Ca., so those were the biggies for me. I just ordered some new levers (brake and clutch) and I also got a couple ngk sparkplugs with the order. Next week, a six pack grab bar. I should be set for OW on New Years! Have fun and grats on the bike!
Congrats!! You'll love the SE, it has descent power and handling. I would recomend riding it a few times thru break-in to find out what you like and don't like before you run off and spend your dough. Between the power mods and suspensions that are availiable for the 700, you can turn it into a pretty wild machine! But do not forget the riding gear, that would be my first purchase if you don't already have it, the stock machine will bugger you up just as fast as a modded unit.
Have Fun with it!
