Definitely a home hack job.... the rear wheel arch is also a give away.
I'm thinking it was some sort of popular mod back in the day as this is the third such R100/Familia I've seen with six lights. Looks really dumb.
There s a 1973 Familia GS with the light treatment at Garage Star Field-
That's a sad picture. Do you have a higher-resolution version?
you want to cry harder??
Well, I can kind of see the dash in the picture. It'd be neat to see it closer up. But it's not a huge deal!
The blog says it could be a prototype RX-85
I've no idea if the RX-85 had 6 tail lights!
Poor little R1! Damn that rear bumper looks pretty neat still! My R100 definitely doesn't have that, looks terrible.
What does the decal/sticker say under the left hand side lights?
btw you can easily tell that the extra lights are dodgy home made shit, the metal trim panel doesn't go around them...
