Very Cool KTM 50

[Chakka]

I stumbled across this photo and many more of this bike a few nights back looking at European enduro sites. Any ideas what components it uses? Looks like a custom frame, conical ft hub, but standard MC style gas tank, seat & swingarm. Way Cool!

KTM made some 50cc Sachs powered bikes.  I believe it is production. There were no Pentons made like this as the Americans didn't go for the ultra small bore bikes.

This is a KTM 50 GS ,build by Heinz Brinkmann (sitting on the left).The same Heinz B. who won the ISDT in Italy OVERALL on a 50cc.
His Son Thomas is now riding this bike in the German Classics.

Ktm built only two prototypes of 50 cc but never ktm 50 was sold.
These are the only original ktm 50 bikes (they never were sold):

This  bike is in the court of the factory in  Mattighofen, I think it was aboout 1971/1972




In the motorcycles fair of Milan (Italy) in 1973:



Bernhard Brinkmann built some ktm 50 special bikes, but Brinkmann's ktm 50 bikes aren't original ktm. The ktm are built in Austria and not in Germany!

Maurizio,

   It is good to hear from you again. You say that only two 50cc machines were built and you have posted a picture of one, this may possibly be the other.

  The picture was taken at a display the POG assembled for the KTM dealers annual meeting in the USA.

Can you possibly get the frame and engine serial number from the one you have a picture of?  Is the 50cc machine you have pictured still at KTM?

Also, have you ever seen the proto-model Penton or do you know where it is today?


Thank you.

Back during the Penton era, as the Japanese companies began to build "mini" bikes, (I don't actually know who) somebody from Penton Imports tried to get KTM to build a "mini Penton". KTM did build two different versions of "smaller", but not actually "mini" sized Pentons. The bike in the picture that Paul posted, was one version and is still over here, but the other version, the first one that Maurizio showed, was here too but went back to KTM at some point, though I don't remember when.

The 50 that is still here, is more of a version of the steel tank frame machines and the one that went back to Austria, was a CMF version.

Hi Paul,
thank you for the kind words, I'm very happy to talk to you again.
I don't know the frame number, I think it's improbable that proto-models have the frame number.
The proto model- Penton or Ktm I think was lost.
Perhaps it's possible that there is still some ktm 50 of
the official Ktm Team. Infact the italian rider Arnaldo Farioli raced on a ktm 50 in the 1965.
In the pics you can see the ktm 50 from the ktm official team (I think 1970):

I phoned to Franzkappa, the best italian Ktm expert, he told me that an original ktm 50 is in Italy in the city of Padua.
The bike has regular italian title.
The lucky owner should not ever sell his rare ktm.

I'd kill to get my hands on one of those 50's with the MC5 style frame....such a neat bike! Thanks for all the great photos Maurizio. If I ever get proficient at welding maybe I will try and build my own.

Can anyone tell us what is "wrong" with that last KTM 50 that Maurizio posted? I definitely know that there is something wrong with it.

Missing exhaust shield?

The countershaft is exposed which will allow dirt and water to enter the tranmission.

Dane ,
 The cylinder and head are different. Is it an 80 cc? Dwight it
 looks like they plugged the tranny shaft with a brass freeze type plug
