1986 Ayrton Senna Lotus helmet.
This amazing original Bell helmet was worn by Ayrton at the 1986 Belgian GP at Spa where he finished 2nd in the Lotus 98T, then at several other races including France. It is complete with radio system – including ear plugs, cables, jacks & microphone. There are some lovely photos of Ayrton wearing this exact helmet, including one by Keith Sutton on page 37 in the FOCA Yearbook.
Very expensive, serious enquiries only.
