German riders Rolf Witthoeft and Herbert Schek were legends in their riding era which was partially due to the longevity of their time riding and also they became best known for riding some of the largest bikes to ever, later known as the Bull Rider Class. These bikes over 750cc may not have had the greatest power to weight ratio but they were powerful and it took a good rider to get these items of heavy metal around a typical ISDT course.
