Almost cabin fever time*


Recommended Posts

"The very successful twin cylinder 125cc led to the square four 250 Suzuki RZ 63, essentially two of the 125 engines coupled together. Known as ‘whispering death’ due to its ability to seize without warning, the 250 never finished higher than third throughout its career and the project was shelved."

 

Hmmm?

I don't think I did. The chain is on the other side, there are frame gusseting differences; but it's a racing machine, so who the Hell knows? I was just going on the "whispering death" soubriquet. If anything ever looked like it would sieze at the hint of a cloud in the sky, that machine is it. The Jawa looks more like it but was only ever watercooled from what I can find out.

 

Time to break out the book of Russian motorcycles.....
