Crazy Englishman / Verrückte Engländer, 1000 miles on a 1958 SR2!

No problem, Tom. You must say: 1,5 horse power, 1,8 , 2,3 or I must need special tools to bring it to "heaven". I mean... ...Formula one- like.

2.3?! Wow, the power! My face is the same as my avatar. Would that still be under 50cc? This is the only rule for this journey.

Did you want more pictures and details of my SR2 or the red and white one?

Tom, 2,3 PS and official 50 ccm is not a problem. The old mopeds from simson called "Spatz" or "KR50" had haved this engines. The same engine like a SR2. Only a little bit a diffrent cylinder, carburator and so on. From outside you can`t see this diffrent. But its a little bit more "fire under the backside tire"

Other thing: If you have on your long way in example a distance "flat land" use a chainwheel with 17 edges. On hills use 13 ore 14 edges...It helps and is a work of 5 minutes to change.

Cool! I might even go faster than the toilet bowls with their restricted top speeds.

I will add a couple of different sprockets to my shopping list.

Yea, sproket was the word I`d have forgotten. fuckin english...

Most English people wouldn't know that word!

I had a bit of a play with the Simson this afternoon. Removing a few parts just to get a better idea of what lays beneath. I also calculated that a full restoration would cost somewhere in the region of 1500 Euros! I'm tempted to just do a mechanical restoration and keep the patina and character of the original parts.

COOL !!! A SR 2E ! It has 1,8 horsepowers .
The Spatz (Sparrow) has 2,0 hp with "Rheinmetall"-Engine, with "Simson"-Engine 2,3 hp .

Do you have the right carburator for your SR 2E ?

I have an SR2E?! Great! Though I thought they were made from about 1960 onwards.

The carb is an NKJ123-4. It also has 6/1 written on it. Is this correct?

I'd love to make it look like this:

We have here the user "BlueKr50". He can bring your motor parts to a finsish like the pic.
The carb NKJ 123 is the right one for your engine Rh50 II. The Number 123 say 12mm of airhole through and the 3 ist the Number of series. Its standard.

It is possibil to do anything inside of the little engine. Than it works (with a bit of more power) also with a carb 134 (13mm airhole). Always 50ccm!! The compression is higher, more fuel (air/benzin) gos inside and so on...

If you would know the correct date of building, we must know the framenumber. Also the enginenumber. The framenumber is on typplate and on rightside underneath the saddle on frame on top.
The motornumber is on leftside the motor on top in near the left pedalarm.

You can also have a look a the list of SR1/2/2E from the user.

(click on the link at the end of statement and open the excelfile). Search a number in near your framenumber and you can find your date of production.

It is a good idea, your SR keep in original style. The mecanical upgrade is expensive enough...

edit: Bevor you buy anything of spareparts, ask here!!! The reason why is: not all of spareparts are working well. Anything of this are chinese "Schrott".

Thanks, here's photos of the numbers:






When I bought the bike, I negoitiated into the deal that it would come with a letter from "The Vintage Motor Cycle Club" to prove it's date of manufacture. This is needed as part of the registration process here. The letter states it's a 1958 as does the plate on the frame. This looks to be correct in your spreadsheet too.

Would the different numbers suggest that the engine is not the original one? Unless of course there were 10474 Simsons that didn't have an engine!

Oh, oh . You've still got a SR 2 . But it has the new front fork of the SR 2E .
In 1958 was the SR 2, not yet SR 2E !
SR 2E cames since 1960 !

You have an SR2 -> its engraved in the small black Plate unter your seat (your last pic)

hagen

Its 58 and the engine is the original! Its absolutly normal, we have a diffrent between frame- and motornumber. Round about is this the factor 1,03.
Alex, I think, the front fork (and any other parts) are spare parts a little bit later. An accident or so...
Its normally and often seen. Look at the diffrent colors.
Also this engine can been upgrad to (50ccm!!) more power. Its a little bit a diffrent, what you need: topspeed or power in low rotation. Together is not possibil.
My intension is always "power" because you can work with diffrent sprokets (Ha, I have a new word in fuckin english ) Without power you can`t go well on hills and you get also nothing of speed. Without power your are always a sleeper....
