investments in Austria asked Lefas to develop a new frame (incorporating his front design) around a Triumph engine with the intent to produce the bike. Work on the new frame had started when Lefas became aware of serious health problems. In a move to "secure" a reliable prototype for future production (as he realized his deteriorating condition), he chose to perfect the 1994 motorcycle model before attempting to complete the new development. Thanassis Lefas died in December 2005 at the age of 53. References "The last motorcycle by Thanassis Lefas", article in (Greek) R&D magazine, issue 14, June 2006. L.S. Skartsis and G.A.
