de Coster Roger
  

Info:

Ende der 1960er-Jahre startete Roger DeCosters Rennkarriere richtig durch. 1966 gewann er den belgischen Meistertitel in der 500-ccm-Klasse und nahm im darauffolgenden Jahr an Weltmeisterschaften teil. Der Erfolg kam nicht über Nacht. Hingabe, harte Arbeit und ein akribisches Training im Motocross zahlten sich aus. 1968 gewann DeCoster seinen ersten Grand Prix in Italien. 1969 trug er maßgeblich zum ersten Sieg Belgiens beim Motocross der Nationen seit 18 Jahren bei. Fünf weitere Male sollte er seinem Land zum Sieg bei diesem prestigeträchtigen Wettbewerb verhelfen. 1970 traf DeCoster die schwierige Entscheidung, CZ zu verlassen und für Suzuki zu fahren. Mit Suzuki erlangte er Berühmtheit. Auf einem neu entwickelten Motorrad – der RN370 – gewann DeCoster prompt seine erste Motocross-Weltmeisterschaft in der 500-ccm-Klasse. In den folgenden fünf Jahren sollte er vier weitere Weltmeistertitel in dieser Klasse gewinnen. Mitte der 1970er-Jahre hatte sich DeCoster als der größte Motocross-Fahrer seiner Zeit und wohl auch als der beste aller Zeiten etabliert. Neben seinem Weltmeistertitel trug DeCoster maßgeblich zur Popularisierung des Motocross-Sports in Amerika bei. Er kam in die Vereinigten Staaten, um in der Trans-AMA-Serie zu fahren, in der die besten amerikanischen Fahrer gegen die besten Europäer antraten. DeCoster gewann die Trans-AMA-Meisterschaft vier Jahre in Folge (1974–1977).

Events & Results:

YearPositionChampionshipBrand
2018

Roger de Coster will become Motorsport Director North America for the entire group (KTM and Husqvarna). He will hand over direct management of the KTM team to Ian Harrison.

2011

Roger de Coster takes over as Race Team Manager of the US KTM factory team with the aim of leading the brand, which has had little success in the USA, to the top. He brings Ian Harrisson with him from Suzuki to KTM. South African Harrisson started out as a mechanic for Greg Albertyn and became world champion with him. KTM offers De Coster exactly what Honda and Suzuki had denied him: complete freedom to make decisions and a massive budget.

2010

Roger de Coster's contract with Suzuki is expiring. When he asks for a meeting with Suzuki management, they refer him to Yoshimura, the tuning partner that co-operates the team. De Coster feels this is a demotion, as he works for Suzuki and not for Yoshimura. Due to the economic crisis at the time, Suzuki is acting extremely cautiously in Japan and the US and only offers him a one-year contract extension. But de Coster wants security and a budget to remain competitive in the long term. Suzuki, however, refuses to make any long-term commitments.

1995

1994

Roger de Coster becomes executive editor at US magazine Dirt Bike Magazine. He writes monthly columns ("Classic De Coster") and is also active as a test rider. He enjoys objectively evaluating motorcycles of all brands, which gives him a new perspective on the technology of the 1990s.

1993

Honda does not offer Roger de Coster a new contract as team manager, but instead wants to push him into a purely administrative advisory role, far away from the racetrack. He therefore leaves Honda.

1980
