What does it mean hi-breather frame?

Hi Maurizio!

These first 2 photos are of Jeff Penton.

Maurizio,
The "high breather" frame means that the air intake for the engine, is taken in the top frame tube under the gas tank instead of under the seat or the side of the air box.

Those bikes are all Pentons, not KTM's, so I assume it was easier logistically for the Euro KTM sponsored riders to have bikes provided from Penton rather than ship them over? Did the US Trophy guys usually get their bikes from Austria for Euro ISDT races?

The reason why Maurizio wanted a photo of a '73 Jackpiner, is that on the http://rugginose.forumfree.net/ website (a very cool vintage site!), a member posted some pictures of his restored '73 175, and stated that it had been ridden in the '73 ISDT.

The frame number is 54 307 66811.
I think that it's very probably it is a Ktm 175 which had been ridden in the '73 ISDT by the Italian Trophy Team.
The bike was totally restored becouse it was in  vary bad state.

Very nice bike!  Interesting the way they ran the clutch cable, and the case saver bar on only the cluth side.

I thought it was interesting that a '73 already had a conical rear hub.

Acron Rims too Lew !! ? The only reason I don't think its a 74 is the 32mm front forks

Check again. They're 35's, I believe. Maybe an early release for the ISDT?

Very good observation, Lew.

That's was one of the details of the bike that was first discussed on the Rugginose site. If you look at the first photo of Jeff Penton's bike, you'll notice that it has a conical hub, too. I intentionally chose that photo for that very reason. By the way, the Italian word "Rugginose" translates to "Rusty".

Another detail that was discussed is that the bike has Magura ISDT lever assemblies with the orange adjusters. Here's a photo and a translated post that the bike owner posted today:
 
"Maurizio, here the photo of the departure of the ISDT USA 1973 with the KTM 175 pilots: from sx Stockemeier, Hall, Jeff Penton and Saravesi. With regard to the discuzzione of the Magura levers with orange registry, it can be seen that they had mounted to them."
