Ok, i found this thread while looking for information on mr. Lefas bike , i don't know much but i will share what i know.
The creator/designer of the bike is Thanasis Lefas (from Athanasios not Aristotle nor Archimedes, it is a christian greek name that comes from the word athanasia wich means immortality, Thanasis also happens to be my name , hence TNS)
This is a one off , it is not a frame kit, actually if you look close to it you will see that there is no frame and that the engine is the chassis.
It has hub steering, the suspension is a coil over much like the rear, that sits over the cylinder heads. (i attached the other 2 photos i have found on the net, so you'll know how it works , since i can't describe it better myself)
wilson59 commented on the aesthetics of the bike, i don't find it beautifull either, but let's not forget that it was made in the mid 90s (
AFAIK) in someones garage and if you look at it this way , then this bike is way ahead of it's time.
@spyvito the greeks that steer from the rear are in percentage at about the world average, so if you ever happen to be in Greece with a date, don't say you hadn't been warned.
I also found online an old article from a greek magazine that rode the bike and the tester praised the bike.
It is indeed a very unconventional bike, that's why i like it.
Have a nice day
Thanasis
