 As motorcycles are forbidden to participate in industry pool sessions and after-hours test sessions, "Performance Bikes" were forced to test during quiet mid-week tourist sessions, where speed limits apply in some sections.This means their lap times are measured from bridge to gantry (see below) and are approximately 22 seconds shorter than a full Nordschleife lap.Nordschleife runs are conducted or observed by various other media outlets, such as the British "Evo Magazine" or "Auto Bild" from Germany.
