Title: SOLVED: si_023 - AWO/Simson - RS 260/6 - 1957-1958
Post by: sichel on August 05, 2021, 04:50:00 PM
Who is able to recognise the engine from this small picture?

Which manufacturer? Which model? Construction period? For one point.

I would like to try something for such difficult puzzles:
As long as there is only the small picture, two points are awarded.
When the change into the black hole is imminent, there will be more pictures and and the score is reduced to one point.
I am curious to see how do you like it.

All I know about motorcycles is that most of them seem to have two wheels.

But I like the idea of two points offered, and half-price beyond the sell-by date!

Overhead camshaft, I guess;....did the manufacturers also build single-cylinder versions of this design?
Title: Re: si_023
Post by: gilescooperuk on August 16, 2021, 08:01:41 AM
Is the engine manufacturer the same as the motorbike it sits in?

I.e. Honda engine in Honda motorbike
Title: Re: si_023
Post by: sichel on August 17, 2021, 06:00:27 AM
@ FrontMan: Yes there was a closely related single-cylinder version.

@ gilescooperuk: Yes, frame and engine have the same roots.

No. FrontMan, you are dirctly looking at an overhaed-camshaft, MZ only built two-stroke engines and some experimentell wankel-engines.

I am grateful for the information :grad:;....is this machine from the 1960s ?
Title: Re: si_023

No, a little earlier.

Title: Re: si_023
Post by: sichel on August 21, 2021, 09:35:56 AM
Good Idea, but unfortunately wrong. Neither Imperator nor Horex. But there were even more four-stroke racers in Germany.

Double overhead cam (DOHC) chain driven?

Yes!
Title: Re: si_023
Post by: fromwien on August 29, 2021, 11:39:48 AM
Has the company built this engine only for race use or has ever existed a street-bike with this engine?
Title: Re: si_023
Post by: sichel on August 29, 2021, 11:46:51 AM
It was a thoroughbred racer!!
Title: Re: si_023

Mid-50's? 1955?
Title: Re: si_023

A llittle bit later.
Title: Re: si_023

1957?
Title: Re: si_023

Yes, that was the starting year.

Simson RS350/7?
Title: Re: si_023
Post by: D-type on August 29, 2021, 04:38:58 PM
Was the engine used to power anything else in addition to a motorcycle?
Title: Re: si_023
Post by: sichel on August 29, 2021, 05:25:49 PM
@ fromwien - Simson: Yes, RS 350/7: No
@ D-type - Not that I know of
Title: Re: si_023
Post by: fromwien on August 29, 2021, 06:31:56 PM
so it is a Simson with 250ccm, right?
Title: Re: si_023
Post by: sichel on August 29, 2021, 07:51:05 PM
Yes, locked for you to find the model.
Title: Re: si_023
Post by: fromwien on August 30, 2021, 03:35:11 AM
The Simson RS250/5 was equipped with a single-cylinder DOHC-engine,..
the cams of the 350/7 were spur-gear-driven(?), not chain-driven (?) (my fault with an previous answer????),.. the only missing twin is in my opinion:
Simson AWO RS250/6 (by Werner Strauch)?
Title: Re: si_023
Post by: sichel on August 30, 2021, 07:28:20 AM
it is indeed the Simson RS 250/6. Therefore you have earned the two-point bonus first  :applause: :applause:
To the different versions of the AWO/Simson RS: RS 250/5, this single-cylinder version is accompanied by another small contribution in a moment.
RS 250/6: First version had a triangular chain driven camshafts, like the single-version. There was a late version with king-shaft-driven inlet-camshaft and connection through spur-gears to the outlet-camshaft. There should also be experiments with desmodromic valve control.
RS 250/7: This was the last Version of Somson 4-stroke racers. So, there could also be used the king-shaft / spur-gears version of camshaft driving. But I only found pictures with pure chain-drive.

And no some pictures of the AWO/Simson RS 250 single-version (pctures one to four). You can see the same development of the race fairings as with Adler or NSU (see si_034).
Also three pictures (five to seven) of RS 350/7.

There has been a very good article in Oldtimer-Markt-magazine 06-2005 about Simson 250/4 to 6. I remembered that fairly, but I couldn't find the copy of this mag in my library! Hope, I haven't lost or borrowed it to somebody. I can't remember
Thank you for the double-point. I hope, you will not forget to award me as last time?  ;D

I know exactly in which grid square I have this booklet in my attic...
"I hope, you will not forget to award me as last time?" - The feeling is mutual   ;)
