I just purchased a CFMOTO UForce and drove it for less than 10 miles.  The lugnuts on 3 tires fell out.  One tire actually came off of the vehicle. Is this normal for breaking in?

Well...no. Your dealer didn't do his prep. Torqued properly that will never happen. Left loose it will happen with any brand.

Make sure to check all the bolts .When i bought my 600 touring last year , all the tie rods were so loose that the nuts were about to fall off.
