Helmut Dähne (also rendered as Daehne or Dahne, born 29 November 1944 in Altenmark,[1] Germany) is a German former motorcycle racer, active not in Grand Prix races, for which the rather tall Dähne (190 cm[2]) is not well suited, but in endurance racing with production machines, comparable to touring cars and rallying with automobiles.

[9] He entered in the German "Seriensport"[10] championship, a series of contests for road legal machinery, where he could test and showcase the products of his employers.

[14][15][16] In the 8 Hour race at the Nürburgring, then still 22.8 km long, he and partner Alois Tost finished second behind a factory-entered Honda RCB.

For enthusiasts still willing to ride the Green Hell of the Nordschleife, timed contests were offered as the Seriensport Zuverlässigkeitsfahrten (Zuvi, reliability runs), which contained a single lap time trial run from standing start, thus eliminating at least the danger of riders colliding when racing for position.

[20] After the 1993 event, an onboard-video was produced[21][22] in which Dähne did another lap, about 10 secs slower, carrying camera equipment on his back.
