These are from 2013, the top clamp has been opened up to fit older spec. 22mm vs 25mm offset. extra forward bar mount, and thicker. helps the run wide issue in older yz450 perfect for ice, makes bike super stable. also have a 2004 ecu has a crazy low end power curve and lower rev limit( save them valves).
