Same as the others....rock steady. On a trip with a lot of other brands and 40+ mph crosswinds, I was the only one not complaining about being blown all around.
You didn't say if you purchased new or used, how many miles are on it, tire condition, etc.
Two potential easy things:
1) Relax. Don't put a death grip on the bars and see if that helps. Many have stated that until they did this they were blown all over the road by semis. After relaxing, no problems.
2) IF your front wheel has been off for any reason, slightly loosen up the axle and bolts around it (finger tight so it is not too loose). Mount your steed and push up and down a few times to compress the front end and let everything fall into place, THEN tighten the axle, then the two bolts. This has fixed many users swerve problems.
If the problem is still there, take it to the dealer!
