Triumph - TWN Motorcycles
Made in Germany
Triumph TWN History
A native of Germany, Siegfried Bettmann founded the Triumph factory in Coventry in 1886 where he built bicycles. A decade later he built another Triumph factory in his home town of Nurnberg. The English factory built its first motorcycles in 1902 with the German plant following suite in 1903.
The German factory built machines with the same engines as, and otherwise very similar to, the English bikes up until 1929 when the economic and political climate in Germany forced a change to home-grown components. Subsequent models were produced with MAG and Sachs engines. During this interwar period there was a legal wrangle with Triumph UK which resulted in some German models being badged as Orial, but after complaints by a French company of the same name the company settled on TWN - Triumph Werke Nurnberg.
After the second war the factory was merged with Adler (in 1956) and German-built Triumph motorcycles ceased production.It is likely that rebadged Hercules mopeds were marketed as Triumph during this period.

DKW RT125 Deluxe 1939
Trying to find a engine for my Triumph b125 which looks like it used the same motor as the DKW RT125 deluxe 1939. Mine is a 1940 built in nuremburg, Germany at this time the triumph factory was taken over by the german gov. and the motors seem to be very hard to find and information is also hard to find. I have searched for hours upon hours for a motor that would work and it needs a right hand drive gear setup 125cc motor and the DKW motor is perfect. Do you know of anyone who has this motor for sale or knows where I can get one. Thanks Tony R.

TWN "Prior" Motor Scooter
Hello, I have just purchased a PRIOR Motor Scooter that I believe was made by TWN and looks exactly like the Contessa. However, my Prior has a Sachs 200cc 2stroke engine almost identical to the KR200 and 201 Messerschmitt's engines (of which I own one of each). I assume it is of 1956-1960 vintage but cannot find anything on the Prior on the internet, only contessa with the two pot engine. Any help or contact with other owners would be appreciated.

It's nice to hear from another lover of older motorcycles and scooters.
I forgot to mention I also had a Cushman Husky right before I purchased the Tessy. I mowed lawns and carried one of our local newspapers, to pay for the two scooters.
I'm not to sure if I have any photos of either the Tessy or the Norton. Well, that is actually not true, I have one photo of the Norton right after I was in an accident in January of 1967.
I know, riding a motorcycle in January her in the U.S.A. is a little, strange, but if you have ever lived in a climate where we have snow in the winter, you would understand the word "strange".
I will have to look through my photos and I'll even ask my mother if she may have saved any photos of me with the to putts I mentioned.
The accident I mentioned, was in January of 1967, a automobile ran me off the road. Needless to say, the driver of the auto did not stop or even slow down.
You might want to check back with me to keep me reminded to look for the photos.
homebrewer-02 at yahoo.com
I did find one old photograph of my old Tessy. It's not a very good photograph, but it is a photo that you requested.
I would like to say, that that little scooter would run the pants of a Vespa scooter or even the Lambretta (spelling, not sure).
I would even use the Tessy to deliver my newspaper route, it was very quiet and a lot of fun.

1954 TWN Information
My father owned a beatiful 1954 TWN German bike. 350 cc 2 stroke, 100% ORIGINAL. I don't know the model; maybe a BOSS, since I'm not where the bike is right now. It is still basically intact and there are some major spare parts that came with it, but it needs some work. It hasn't run for about 15 years. He used it to travel from Uruguay to the U.S. between 1955-1956 documented). I'd like to know if there is anybody interested in purchasing for a collection or the current price for one of those. I will post a some photos pretty soon.

Just surf in at your web page and find my bike at your site. I'm the owner of the bike at the top of the page. It's a TWN BOSS 1954 350cc two-stroke, this picture was taken for Swedens largest magazine of old bikes, and the picture was used in a calendar of old bikes in 1995.
I began to restore the bikes in 1990 and it was finished the next summer. I also have a original Steib LS 200 sidecar for it too.
I made all the work by myself for ex. the paint job, some welding, and I have to made some new parts for the bike too. The rear silencer on both side and new pistons etc.
I also bought some parts from a German dealer, he has a lot of spare parts for these bikes.

I'm from Belgium and I own a TWN Boss 1953. It started as quite a wreck (only 75% original, bad shape, been used for motorcross (I think it had crashed several times), lots of rust, ...).
Nice points were that it did have a sozius and original documentation. By now it has been totally rewired, most original parts have been restored (I don't really replace or reproduce original parts) and most of the non-original parts (like front light, wheels and such) have been replaced by parts I've found in Hamburg (a guy there has the army-stock for TWN BDG250 which has a lot of parts in common with the 350 Boss (BTW: I'll look up the name and address of this guy and post it later on)).
I'm still looking for exhaust pipes (the end parts) and hope to find them soon (maybe at Motorrad-Stemmler).
Some questions for the group:
1. Anyone know how to connect the speed-cable on the rear-wheel?
2. Anyone experienced with attaching a side-car (Steib)?
3. To James Wolf: How come you show your first pictures on http://www.narma.org/euro/brands/triumph-twn.htm and the final result on http://www.fen-net.de/joachim.fritz/triumph/t-boss.htm ? Nice result and very fast (started only in april???), congratulations!

I have a rare one for you all!
I own (what I believe to be) a 1937? TWN B200 E. The reason I believe this is, the only Photos that came close to my machine are of this particular model in my 6 yrs of research. The only difference is, the front forks have been replaced with the more modern tube style forks, the front fender is from an Austrian Puch and finally a BMW R35 pannier rack was altered and added to the back. However, all the other parts/featuers match up exactly. The frame, engine (vertical cylinder not angled forward) the motor casing and dymamotor, hand shift, Flat bottom tank and emblem, even the 2 piece rear fender! If I add a photo, can anyone help me identify this machine so I don't go nuts? Is it possible to perhaps locate the proper front fender, (Forks maybe) and I need TIRES and TUBES badly. The tires on this machine now are Reise tires dated 1941 and are in really good shape but getting dry (19 X 3,00 front and 19 x 3,25 rear). HELP!!!!! I really want to restore this machine properly, oh and it does run,,, like a top!
Thank you everone!!!!!

Now this is preety cool...like the stories of a dusty classic waiting in some barn for the collector to discover.
Well It happened to me today, a once in a lifetime find.
Its a 1955 TWN Boss Motorbike, it is 99% original condition, (the rear brake light looks odd).
TWN stands for Triumph Werks Nurnberg, there a very few of these. Triumph (British) built in a factory in Germany from 1951 to 1955. It is all class and beauty, brass badges, chrome tank, hydraulic brakes...a beautiful piece of design. You can just look a it for ... like art, it is art, industrial art. All is there and original, seat, brass emblem badges, levers not bent or scratched (never been dropped), German glass lamp lens, exhaust pipes, on and on, I pulled the caked in dust and rust thing out of a garage and delivered it to my home this morning. I washed it off and she looks...well...not to bad (for her years). This is what restorers look for, a classic that is all there and not altered or rebuilt. I will have a total restoration done (here, for the price of a couple of New York diners) and she'll be like new. One day I hope to send it home. It could certainly be a museum piece. I want to share the excitement with you.
This it the TWN I got today.
This biker will look like the one above when restored...
Whatta nice classy classic.
I live in saigon, and I met another American guy riding one, thought it was a beautiful bike, so started looking for one. Well, ask a few people and....was lucky.
BTW I will be reproducing parts...pipes, levers, some clutch parts....who needs what?
