Yes, advertised for years now.
Without knowing the AKL-No. everything is speculation, but I would say it is a customized “normal” AKL – but not out of the famous 27 (42) – series…the so called “original” ones. For a “normal” AKL the price is far too high.
First permission for legal street use out of 1988 and an “AKL-No” does not fit together. But have a look, it is a carburetted engine, this may explain why it is documented as a 1988 ;-) .
Further more it had/has a heater – look at the demister ……..and a glovebox (without lid).
Seats are not original - not from the "original" neither from a "normal" AKL.
