Another very rare German bike to pass into my collection is a ADLER ‘SPRINTER’ in the last years of Adler motorcycle production Adler tried to boost sales by up-rating their MB 250 model first to a swing arm version called the ‘FAVORIT’ and finally to a version in September 1958 called the SPRINTER .The Sprinter power output was increased to 18 BHP from the Favorit’s 16 BHP simply by upping the compression ratio to 6.6 and fitted a larger main jet.Top speed then increased to 126 KPH (82 MPH) Outwardly the only visual change was to a 18 inch wheel size and a small increase in the length of the front forks It sold for 170 DM more than the Favorit only about 320 were made hence they are very,very rare i think there are only 3 in the uk?? also to buy one from Comerfords or Avon Auto’s would have set you back £262/10s/6D They came in 2 colours which was metallic Green or metallic Cobalt Blue but not Black as below !! I think a Ariel Arrow cost about £190 at that time. So pictures below of a rare bird a Eagle in fact!! just a bit more info
Adler ‘Favorit’ made 360 frame number 500,000 to 500,751
Adler ‘Sprinter’ made 320 ” ” 500,000 to 500,751
Adler sixdays made 20 ” ” 500,000 to 500,751
Adler Moto-Cross made 50 ” ” 5000,000 to 500,751
as you can see all 4 variants were given the same frame numbers so a total off 750 were made. There is also more of a mystery relating to ‘what is a Favorit or a Sprinter with frame numbers covering both models the same !! i have seen FACTORY photos showing a Sprinter with Favorit forks!! I think the identification problem is when the production of both the Favorit and Sprinter was coming to a end it became a case of’ mix and match’ to use up all parts that was available!! perhaps the carb could be a clue? the Favorit carb was a Bing 2/22/28 and the ‘Sprinter was a 2/22/29 .
PS you could buy a over the counter race kit which then gave you 22BHP so many Favorit/Sprinters were turned into rennmachines/club racers.
