Harold Koehler's Phantom
This is the first load of parts from the barn. As you can see there is much to do.

            It can be said that art is an expression of the mind that cannot be placed into words. It is my opinion that if you believe that art can only be found in the form of pottery or canvas, then you truly are a savage. I believe that it was Frank Lloyd Wright that expressed that architecture is what we refer to as a “sermon in stone”. Architecture should express beauty, functionality, and be thought provoking. Many of us believe that machinery parallels this philosophy. Machines are much more than a sum of inanimate parts. To many of us they take on a status of life. At a young age I found many machines to be beautiful and thought provoking. In my eyes, the OSSA Phantom was that functional beauty.

            In 1975 I bought an OSSA Phantom from a friend of mine that had ridden it to much success during the previous season. Fortunately he had the resources to purchase a new bike every season. He was quite taken with the Phantom and was going to directly replace it with a new one of the same year and model. I had worked in the rice harvest that fall and happily purchased the bike for $800. If you have ever worked a harvest in agriculture you know that your daylight hours are spoken for. One fall night I purchased the Phantom from my friend and after work rode it in a very dimly lit equipment yard. I smiled all the way home. 

            For two seasons the Phantom was a joy to ride. It was light, fast, and had torque and horsepower that seemed to never end. My Phantom, as well as my friend’s, was in constant development. The mid to late seventies were the golden years for long travel suspension development. We laid the shocks down, installed dampening rod extenders, and built up pipes for the two Phantoms. You wouldn’t believe how excited we were when we learned of the two Phantoms that Marty Moates and Kenny Zhart were riding. And what was even more encouraging was that our Phantoms shared many of the modifications that they had.

            After time, the two Phantoms would fall prey to the typical afflictions that plagued the mount. The missed shifts, poor fork dampening, and chain problems became demons that broke your concentration. After a bone jarring, shift missing motocross race in 1977, it was decided that a change had to be made. The Phantom was retired from motocross, and was replaced by a Bultaco. However, the engine would have a future on the short track. The Phantom engine served this purpose well. As much fun as I had racing short track, career ambitions would draw me to Oregon. In 1980 I parked the OSSA, bought a new Maico and moved to Oregon. Until its recent resurrection, the short track framed engine, and the balance of parts would reside in the barn for some twenty seven years!

I hope that I would look this good after being put away in the barn for 27 years!
The beginnings of the frame rebuild. The aft end of the frame was reconstructed so as to stay within the AHRMA Historic Class 9” travel rule. I also wanted to cleanup the original modification.  
Modification complete and ready for blasting.
One final check fit.
During the restoration I believe that I have solved some of the problems that plagued the early Phantoms of the past. The early Phantoms had the transmission lay-shaft supported by bronze bushings. The bushings would wear out and let the shaft float excessively. The shaft is now supported with full needle bearings. I have also lightened up the shift drum. It was reported that the inertia of the drum caused some of the missed shifts. Mr. Newton would tell you that “bodies in motion tend to stay in motion”. The forks have been replaced with 1979 Husky forks. The rear has a full nine inches of travel with Works Performance shocks. You will also notice that the bike now has a modern style chain guide. The original was too far away from the rear sprocket, and just a bit too sloppy. The brake shoes have been replaced with modern semi-metallic shoes that actually work. And lastly, the bike is now painted with two part automotive paint that won’t blow off at the car wash. Other than jetting the Mikuni carburetor, I am proud to say that the Phantom is complete. The first ride was everything good that I remember from the Phantom of 31 years ago. And of course with the improvements, it is even better. Looking back, the bike had given me much pleasure, and deserved to be restored.

With the passing of Marty Moates I believed that it had to be done. Do machines take on a form of life? Are machines much more than a sum of inanimate parts? I would have to answer both of these questions with: Yes they do, and yes they are.

Now we are getting somewhere!
We finally have a rolling chassis. The Phantom now sports Marzochi triple clamps and modified period Husky forks as approved by AHRMA. If I had installed Marzochi or Husky forks back in the day, I might have raced it one more year.
The Phantom is about to the point that it can move on its own power. No longer will my Wife have to push me down the street while I make motorcycle noises.
The day has finally come. The last bolt and nut has finally been finally installed. Much like any bike, this will be the cleanest it will ever be again.
Here we are finally in the field.
No doubt, the Phantoms were a beautiful bike.
It doesn’t get much better on the “flip side”.
