hi i got the 250, make sure you lock tight the air box, back two mud guard and the rear sub frame bolts up or they will shake loose and come out trust me!!!!!
Just keep a eye on all the bolts at first, I check the whole bike after a trial after loosing several lol
I have changed the seals on mine after the bike was 2 months old they were shot, nut its a easy job to do.
keep a eye on the rear brake too i had my master cylinder replaced under warranty only last week, the brake went realy dull i changed the pads n seals but no good, its fine now though.
hope it goes well
