Botho G. Wagner then worked in various ways to promote karting. He was editor of the magazine "Karting", which was published until the 1980s. He was a member of numerous commissions in karting clubs and represented Germany in the International Karting Commission.

Since 1993, he and his wife Alice organised the world's largest annual karting fair, the IKA-Kart 2000 in Offenbach (DEU), near Frankfurt am Main, every year.

The CIK-FIA regrets the death of a very dear personality who dedicated his life to the development of karting, and sends its deepest condolences to his wife, his family and his loved ones.
