The build quality is top notch! Don't fret if it doesn't match the OEM setup, even if the instructions say otherwise! The OEM is a 2O type (over the fender), but these CoreMoto lines are 2F type (double banjo, single dedicated line from master to each caliper). The description does not list this, but the CoreMoto website explains kits will default to this 2F type for better performance.
