I had bent two Duke 2 BBS wheels inside of a week, the spokers that replaced them went over the same roads & speed bump highway joints that lofted the bike into the air without issue for 18 months.
My supermoto has a flat spot on each wheel but the 60' MX jumps have more to do with that than the street. A set of TUV (Euro standard like DOT???) approved wheels in cast would have folded already. They apparantly mandate a softer material to allow the rim to bend rather than crack but it bends very easily, see any BBS wheel for road use, KTM, VW Corrado,,, Great smooth as a new racetrack road wheels but not for real USA roads in this day.
