In 1953, businessman Ernst Kronreif became a major shareholder of the company, which was renamed and registered as Kronreif & Trunkenpolz Mattighofen. In 1954, the R125 Tourist was introduced,[17] followed by the Grand Tourist[18] and the scooter Mirabell[19] in 1955. The company secured its first racing title in the 1954 Austrian 125cc national championship.[20] In 1956, KTM made its appearance at the International Six Days Trials, where Egon Dornauer won a gold medal on a KTM machine.[21] In 1957, KTM built its first sports motorcycle, the Trophy 125cc.[22] KTM's first moped, named Mecky, was launched in 1957, followed by Ponny I in 1960 and Ponny II in 1962 and Comet in 1963.[23] The 1960s also saw the beginning of bicycle production in Mattighofen. Ernst Kronreif died in 1960.[24] Two years later in 1962,[25] Hans Trunkenpolz also died of a heart attack. His son Erich Trunkenpolz took charge of the company's management. As the company continued to expand, the workforce totalled 400 in 1971, and forty years after it was founded, KTM was offering 42 different models. Additionally, KTM was able to produce motorcycles for the racing industry. During the 1970s and 80s, KTM also started to develop and produce engines and radiators. Radiators sold to European car manufacturers constituted a sizable part of the company's business in the 1980s.[26] In 1978,[27] US subsidiary KTM North America Inc. was founded in Lorain, Ohio. In 1980, the company was renamed KTM Motor-Fahrzeugbau KG.[26] One year later, KTM had about 700 employees and a turnover of 750m. Schilling (about 54.5m. euros). International business then amounted to 76% of the company's turnover.[26] However, scooter and moped turnover sank rapidly, and production had to be halted in 1988.[26] Erich Trunkenpolz died in 1989. Takeover of a 51% interest in the company by the Austrian investment trust GIT Trust Holding controlled by Austrian politician Josef Taus in 1989 was followed by unsuccessful attempts to turn the indebted company around,[28] and in 1991, management of KTM was transferred to a consortium of creditor banks.
