I know these bikes are technically off-road bikes, so it could be the stock knobby tires the bike comes with (I am assuming you are riding on the road?) giving you issues. Of course, check all the nuts and bolts and whatnot first, but I wouldn't put it past the stock tires which I assume are somewhat aggressive knobbies. People in the past with new bikes, like the Hawk 250 (also technically an off-road bike which may still, but I recall used to, come with fairly aggressive knobby tires), have complained about wobbles and ended up changing out their stock tires and seen a near complete fix.
