Frederick John Osborn of the Osborn Engineering Company built his first motorcycle in 1901 using an MMC engine. After WWI he produced OEC-Blackburne machines, and the name later became OEC.

Hi there, Hope all is well. I came across an OEC motorcycle which I took interest in purchasing, but do not know much about it, and while trying to gain more info about it I found your site. If you could help me out in any way i would greatly appreciate it. This is the info I have according to the bike log book; Manufacturer - OEC engine capacity-197 Year of manufacture-1949 I would like to have some expert advise and more info about it. Is it a 2 stroke? How rare this bike is? Is it a valuable bike? How much is it worth paying for in the condition it is? (Attached pics). What's the value of it after restoration? Are parts available? Thanks for now and looking forward to your reply. Keith.

Purchase Informations
OEC Atlanta 500
Interrest to buy that bike. Questions: Are there Operating, spare parts manuals available?

Austria

Thank's for your effort.
What i find out at this time : OEC fitted with Matchless engines up to 1937, later they use AJS engines.
For both brands spare parts should be available.
One basically question: Did the supplier of the engines at these time ( e.g. AJS ) useing their own gearboxes or is there one manufacturer and supply different bike producer with the gearboxes?
I think the Commander with the duplex steering system is more unique than the Atlanta.
Do you have an idea how many peaces are produced from both models ?
Thanks and have a great day

I am a little bit confused regarding the OEC bikes.
On the homepage there is a 500 ccm Commodore 1938 looks like the Atlanta.
So they have build the Commander, Atlanta and Commodore with 500 ccm engines
around 1938 ?
Do you have any idea how many of them are build?
I think to look for the bike in spring next year.
In the meantime i will do some small work to finish the restoration on my
Citroen 11CV.
I wish you a Merry Christmas and a Happy New Year 2016
and a lot of fun with the old bikes.
1938 models are shown on this image:

OEC Duplex
Just some info on duplex/dual for setup. My grandfather worked for OEC and apparently the duplex set up was great for straight line speed but a dog through the corners. When they took duplex OEC to the TT the forks only stayed on for the
pictures.

Thanks for the email and sorry I've been so silent of late, but am very busy still working on the ex Sidney Kidman Thornycroft car which is progressing apace, as you can see from the attached pic.
I also spotted and have replied to the message from Paddy Brockerton whose father George rode the works Duplex steering OECs in the 1934 Senior and Lightweight TTs, retiring in both. I am restoring this Senior bike and had tried to track down his team mate Alf Brewin whose story was written up in 1970 in Motorcycle Sport, but who has long since died and no-one seems to know if he had any offspring. Finding George's son is a godsend as he has the all important pics of his father's bikes...
Sadly the Blackburne engines fitted that year were only loaned by Blackburnes and were returned before the bikes left the Island, so I am struggling to find a suitable motor for my chassis. Should be a nice thing when done though.
More power to your elbow,
All the best

Question about OEC
OEC Atlanta Duo
Hello,
I found an old book in my dad's library that had a drawing and short description of an OEC Atlanta Duo. Something about it absolutely intrigued me. I have spent the last few months searching the net for any clues as to if any of them still
exist, or if they even produced any for the public. Any info would be much appreciated. Thanks!

SCRAMBLE /MOTOR CROSS
I once had an OEC Scrambles bike which had a square tube frame and either a Villiers or JAP engine. Can you confirm that this was correct and if it was a genuine factory model. As I am now in my 76th year my recollection may be a little of
track, hence the queston I am asking

Duplex Steering System<
OEC commander
I'm trying conduct a research project on the duplex steering system that is featured on some OEC bikes (the commander I think). I was curious at whether you have any information on the system, or whether you know of any material containing
information about it.
Thanks

I can't find any information on JAP engined bikes from 1924. I do have some on OEC Blackburne bikes. I have uploaded the articles to MEGAUPLOAD in high res tif format. (!Big files)

N.F.WOOD (Fred Wood) was the designer at OEC and the inventor of the duplex forks. He was a friend of my parents, and when he died (1960?) I was given two books of press cuttings and a book of testimonials that he had from the firm.

O.E.C. - JAP 998ccm SV 1924
Dear Gentlemen,
I would like to kindly ask you for the help. So First of all let me introduce. My name is Zdenek Sevcik from Czech republic and I have same motorcycles- INDIAN, ZENITH and some Czech JAWA.
So my problem is: Last month I have found one special type of motorcycle. I hope it is the possibly the O.E.C. with engine JAP 998ccm SV, but I saw only the engine, frame and STURMEY ARCHER. The other parts are missing. According to the engine number this is 1924 year production. But I do not have any type of picture or any document about this motorcycle.
Please if you will find something for me it will help me very much. So please any type of information about Great Britain motorcycles company O.E.C. and their production from the years 1920-1930 is needed. And the picture of OEC
motorcycle with the JAP engines.
Thank you very much for any kind of information.¨
Best regards Zdenek Sevcik

No big deal on this one, just myself and a friend were looking at the JAP OEC record breaker on your web site and were trying to work out how the front steering/suspension worked. They called it a duplex fork not double as I had said.

OEC Frame
I have recently purchased an OEC Frame with Webb Forks as it is all in bits i would appreciate a photo or a drawing or anything that might help me assemble it
I intend to fit a JAP engine i have bought the engine is stamped KOZ/V i understand K to bee 500cc O to be O.H.Valve V to be 1936 but what does Z stand for,
Any help would be appreciated
Regards,
David B Gibson
Having stripped the engine and offered up the crankcase to the frame there is no way it will fit without butchering the frame, the OEC that was fitted with the 500 JAP must have been different at the bottom of the down tube so it looks like i have a frame to sell or swap i still would like help on the JAP engine type.
Regards,
David B Gibson.

Pre War Oec Motor cycles
I was employed By OEC Stamshaw Portsmouth UK in 1945. At that time two interesting bikes were stored. One a normal 1930's model 350 or 500cc with a normal size front wheel and two smaller in line rear wheels . Advertised as being able to go
where a horse could not, also a 1920's frame with I believe a Blackburn engine which I believe attempted the world speed record.
At the time we manufactured 50 speedway frames for Southampton.
Have they survived?
