as said check spokes ,swing arm and head bearings , new shocks are a must do , , new tyres and ride it , if they were as bad as some say there would be no bikes left as they would all be crashed and there not !!!,
, I and many have riden them and most other triples and had no problem with the handling if you know how to ride them , get use to it and you will surprise a lot of people how fast they do go around a corner, just my opinion , they got a lot of bad press due to guys that couldnt ride out of sight on a dark night working at bike mags , if they were so bad how come they use to win races
