In the mid-1990s, Michael Geiger turned his back on the Pro Superbike DM, despite good results, due to insufficient financial strength. In the club sport scene, the Lower Franconian is still present, very successful and is considered one of their most colorful dogs. This is largely due to his racing motorcycle, one that is essentially 23 years old Kawasaki Z 1000.
In 1999, the overall winner of the Thunderbike Trophy, the oldtimer, radically revised by the Kawasaki Z specialist Roland Lenden from Oberursel in Hesse, now drives in the Open Xtreme class of the Club Sport Trophy, which has been completely reorganized by the German Motorsport Association DMSB. In the course of the restructuring of the racing categories from the 2000 season, amateur and popular sports were also completely reorganized. The Clubsport Trophy brings together classes from the previous DM program, the Rundstrecken-Cup and completely new ones. Two races per event and twice the training time than before offer the drivers more action and are intended to curb the massive migration into the free race training scene.
The Xtreme bikes represent the hottest club sport category. There are around 500 cc racing machines from the previous DM as well as three- and four-cylinder four-stroke machines with unrestricted displacement and with technology similar to supersport. And so-called “classic machines” like the Z 1000, which, however, can be largely revised.
Unlike the original, the running shop window of the Kawasaki Z restorer has a TechnoFlex central spring strut, an adjustable swing arm pivot point and a WP upside-down fork. The 180-kilogram racer can put itself in the limelight thanks to its cutting-edge 145 hp, even though the engine block of the 1100 is 16 years old.
The financial side is also not from yesterday: The material value is 37,750 marks, plus around 500 working hours. Master Lenden prefers not to reveal his hourly rate.
At the other end of the spiral of costs in the club sport scene, there is also a very successful concept: Frank Borkovsky’s Kawasaki ZX-R 400, overall winner of the four-stroke challenge in 1998 and 1999. “The ready-to-race motorcycle is worth no more than 7,000 marks,” the man from the Lower Rhine amazed. The small racing ZX-R is based on a 1993 accident machine and has a good 80 hp at around 145 kilograms. The used separator puts the new Clubsport Trophy in the Open Challenge class for four-cylinder four-stroke engines up to 400 cm³, two-cylinder four-stroke engines up to 600 cm³ and two-cylinder two-stroke engines up to 250 cm³ with rules similar to Supersport.
In addition, single-cylinder four-stroke engines up to 800 cm³ start as Challenger. The SoS racers have all the constructive freedom of real racing machines. An example of this is the Pami-BMW from designer Gottfried Michels from Trier, who also used the victorious BMW engines of the Dakar ?? Cairo rally went. He combines his hot single aggregates for the asphalt slopes with British Tigcraft frames to form lightning-fast reindeer under the drivers Manfred Kehrmann, second in the 1999 four-stroke challenge behind Borkovsky, and Thomas Schmitz, fourth overall.
With a price of around 25,000 marks, the 80-hp and 130-kilogram stews are a lot more expensive than the low-budget Kawa. But fans of extreme racing technology cannot ignore the single racers in the club sport world.
The Clubsport Trophy has reserved two classes for the disciples of the pure teaching of the Twins. Machines with four-valve engines compete in the premier league. But to slow down hyper-expensive, disguised superbikes like Ducati 996, Honda VTR 1000-SP 1 or Aprilia RSV mille SP, a sophisticated handicap system applies.
Due to these rules, the Honda VTR 1000 built on the old, more civil version, such as the motorcycle from Honda dealers that has been refined with Moriwaki parts, have dominated the vehicle Wellbrock from Lillienthal near Bremen – also a frenzied market of possibilities. The maximum version has a good 145 hp at 165 kilograms at a price of more than 45,000 marks.
Four-stroke twins with two-, three- or five-valve engines drive in BoT Formula 2. And the DMSB Clubsport Trophy is completed by the Open Street Bikes, street legal three- and four-cylinder four-stroke engines with no engine capacity limit, but limited top performance.
The new sports club offers a colorful variety in the starting field and certainly plenty of fuel in the dispute over the most varied of machine concepts.
