A Brief History of the Marque

Germany 1949-1958
The Adler company built it's first vehicle in the 1870s, a tricycle, and made typewriters from 1895 which became well-known internationally..

Their first motorcycles appeared in 1902, and until 1910 they produced 3, 3½ and 5 HP machines.

After 1910 they ceased making motorcycles and continued with bicycles, typewriters and automobiles.

The company was notable in the thirties for their fine cars which included the Adler Autobahn, Trumpf Junior and the 2.5 litre Glaeser bodied Diplomat.

After World War II motorcycle production resumed in 1949 with a 98cc two stroke followed by improved 123cc, 147cc, 195cc and 247cc designs. The 247cc machine had a modern twin cylinder two-stroke powerplant which had some influence on early Japanese motorcycle engine design and may also have been the inspiration for the Ariel two-stroke twins.

Adler won many races with air- and water-cooled 247cc street racers, driven by Lohmann, Beer, Luttenberger, Vogel, Falk and others. Some all-terrain motorcycles like the Adler sixdays were built up to 1957.

In 1956 Adler merged with Triumph (TWN). The business was taken over by Grundig in 1957, and motorcycle production ceased in favour of office equipment, notably typewriters.

Adler 98ccm Mf
I`m the owner of what I belive might be an Adler MF 2 or MF3. It looks like an Adler MF1 but max load is higher. I can`t find anything about mf 2 or mf 3 and very little about mf 1.
Hanstholm DK

What year is your machine, and have you any photos?

It`s a 1938 and max load 210 Kg, As found a Villiers 9D engine was installed. I.m in Denemark now and the bike is in Norway so the onely picture I have is as found. I found a picture of an Adler MF2 and it`s not that and propably not MF 3.

Is this a good deal
Adler 350
Dear Sir/Madam

I came across this Adler Motorcycle, and was wondering if what the seller says is true, as he states that it is a 1956 Adler 350cc, and as far as I know Adler only made upto a 250, the Motorcycle is 95% all there and the seller wants £500. would you suggest I buy this Adler.

Kind Regards

I haven't seen one of them in years. Your best bet would probably to keep an eye on e-Bay as things like that sometimes pop up. I was recently able to snag one for a British 1935 Calthorpe Ivory that I've been looking for about 10 years. I don't know of anyone selling them.

Good luck on your quest. The Adler cars and motorcycles are incredible machines.. Some of the first front-wheel-drive and I'd love to get my hands on one of the 2.5 litre cars.

I have a thirty-eight adler with pedal start need parts please. -- HounddogNorton at

September 28, 2001
Dear friend,
I have just come across your web-page and saw your request for info on /about Adler. Well, the only Adler I ever saw was back in the late 50's and it was an horizontally opposed twin with plunger suspension and a separate pillion seat with a rubber grip in front of the seat. I am from Limerick in Ireland, in the 50's such bikes as the DKW, Adler, BMW, HRD etc were very rare. I used to drive a BSA A10 with a DA Side-car................ Thhhhhose were the days!!! The days of incontinent machines.

Hi I'm Ronny from Jakarta, Indonesia
I have a Classic motorcycle Adler 125 cc (1953), I want to know a history and all information about Adler motorcycle. Thanks a lot.... please send e-mail to me at Ronnykusuma at hotmaildot com

November 14, 1999
I owned a 1953/55? 250 cc Adler 1956-7 Loved. it, Cute? I mean with the semi Earles front suspension and valanced fenders and15 or 16inch wheels. .And sounded like a gunny sack full of fighting cats.

But don't let looks and sounds fool you, it would top end an R-50 taking half the time to do it. It was a quick little scooter and handled pretty good if my memory serves me correctly. As you can see I was pretty fond of it and don't remember any thing bad about it, maybe one thing, I took a lot kidding about my little motorcycle such as to leave it out in the rain, maybe it'll grow or hey Ron get off your knees--- until they learned what it could do.

Then it taught me a little about 2 strokes, it was the first "real' 2 stroke I'd been around, I was told that it was one of the first to have reed valves and that the Rodriguez brothers raced them, don't know if either of the last statements are correct.

I do know the brothers stated their racing on motorcycles then on to cars in the early 50s.they were from S. America, their careers didn't last long, they were both killed on the race track sometime in the 50s.

A little humor now. I figured with those big twin mufflers it had have a lot of back pressure, no I didn't take them off-I cut them off and made megaphones out of them. ruined my motorcycle, couldn't get a replacement set, I think I almost gave the bike away, it was loud, smoky and dead. But you see that was when I knew everything there was to know about motorcycles.

By the way, that was during the same time my friend had the Victoria Burgurmiester that I liked so well.

I am looking for some help with regard to Adler cars rather than bikes, but maybe you could send in the correct direction. My father bought an Adler car in 1945 that had been in storage during the war. I would like to find out more about the cars and the company that made them.

Saw your website. I don't know much about Adlers, but I do know I have one under my basement stairs! It's an 1955 MB250 . It needs a lot of parts but I do intend to restore it. If you know of any one who may have some used parts please let me know. I need a tank toolbox, exhaust, handlebars, headlamp and taillamp lenses, air cleaner, complete top end, and both engine side covers just for starters.
