Hey, what does anybody know about this bike? The photo came off the VintageKTM.com site with the caption 71 250. This is the only 71 250 I have ever heard of or seen and it looks a bit different from the 73 model we got as a Penton Hare Scrambler. What can you guys see thats different? One thing is the front fender mount looks like its from a steel tanker. Also the engine looks to sit higher in the frame. Neat scoot...like to know more.TTP
Very Cool Mike....you're research is first class !
Where can I buy one !
Victor
Paul,
I'm not able to find the "VintageKTM.com" site. Can you provide the link?
Dane
Thanks Victor, but the credit should go to Too Tall Paul for forwarding this pic for me to post. This bike among other are on the KTM 495 site: //www.ktm495.mxbikes.com
Click on Enter and them on KTM 70's pages under other links, then anni 68-73 for this particular pic near the center of the 4th row of bikes. Mike

Hey, do a Google search for KTM 70 years. What you will see is a foriegn site from Italy I think. If I can manuver this site anyone can. Under the photo of bikes 70-79 is this "71" along with quite a few neat vintage KTM's. Rocket said it looked like a prototype and I agree. We never got our hands on a 71 250 over here and I was hoping one of our Euro friends, Speedy, the Penton family, or anyone in the know back then could shed some light on this one of a kind scoot. Regardless I think it would be fun to build something like it. Hope to hear from yall,TTPaul
I've got to the site where the pictures are shown, and one of the interesting things that I noticed about the two pictures of the bike, are that there is no pipe on the bike in either pictures. Sort of makes you wonder did they forget to think about designing the machine with the pipe on it.
This is definitely a prototype and I'm also very sure that Sigi Stuhlberger built it.
Dane
Do you think it would run well with the way the carburetor is angled at such a radical degree?

This is s link to my website, and the 3rd pic on that page is another pic on a 71 250 "metaltanker",(the gas tank was alloy), I found the pic in a Swedish motorcycle magazine from June 1971.
The picture is "in action" from an Austrian MX event, and I think they won the Austrian MX Championship on it but I'm not quite sure. (As said before Sigi could tell everything about it).
But I really think the bike is quite cool with the alloy tank.

I just spoke to Kalman Cseh on the phone, and he told me that this machine was first built to race the '71 Austrian Championship. It was ridden by Manfred Kleer in the series. It was the first version of the 250cc engine.
The first version of KTM's own engine, was used in the '70 ISDT in Spain in 175cc displacements. There were two machines ridden in the event, one by Lars Larsson and the other by Johann Sommerauer.
The exhaust for this machine, was originally a down pipe like the Maicos of that era.
Dane
Hey, Y'all rock. I knew this bike was special and was quite frustrated when I was too stupid to get the photo posted. Thanks Mike!! This is something I wanted to share with the group very bad.
Building a replica may prove impossible. Alloy tank, non existant air box what else? Dane, do you notice the engine sits quite high in the frame. The carb angle doesn't look that much different from my 74. Downpipe too? This thing must have been a shocker when it showed up at the races. Thanks Dane and Mats, all the info is greatly appreciated and I hope we can meet in July if not sooner,TTPaul
Thank you Dane!
Did Kalman Cseh mentioned how many of these "metaltankers" they made?
In the pic from the Swedish article you can see that this bike has an "over and across" exhaust.

Looks like the 71 bike had the 125 rear hub. Boy if thats the case I bet those rubber dampers went quick!! Did you also notice that the ad from Mats site for the 73 250 has a different frame than the normal 73 250's, st least the ones in the US. It looks like a 73 Jackpiner frame modified for the conical rear wheel. Wow, all very interesting!

Hey Y'all, nobody has really ever said why the carb on this bike is at such a radical angle. Unless it is the photo which I dont think it is the carb is almost 45 degrees to what would be the intake. Replicating this bike is somewhat posible but a few parts are one off and I am not that talented. Kind of gave up on making it a mx'er too cause street legal sounds like more fun. TooTallPaul
