coolant motorcycle

Lovely. What does the signwriting say?

 

There never was a 750cc Jimny, but there was an 800cc 4-stroke four.

This appears to be the 537cc LJ50 2-stroke triple engine:

Oh look, Albrecht seems to have morphed again.

You're right: it was smaller. A 550.

A friend had one. We had a blast seeing just where we could take that
thing.
It would climb a pit bank, and then turn and ride around the pit
bank. It would run under water for 30 seconds or so <VBG>, but
wouldn't float.

 

It was a 500cc, I believe, and in low range would only do about 20
mph.
In high range, it would do 40.
