Oh, now that's a real piece of Norton history. Where on earth do you find it?

Which one is Frank Damp I wonder? :wink:

They ride those dummy sleepers pretty well I think. It's a real testament to the Roadholders that the riders can even hold onto the bars.

Looks like NV were cheating a bit though as the red bike doing the jumps is a Ranger isn't it?

Thanks for posting it L.A.B.

Cheers,

cliffa.

I love the all Silver Commando. Do my eyes deceive me or is it fitted with a smaller front wheel & tyre? It looks very cool I think.

It just showed up on Youtube. Credit must go to 'jamesedwardmeader' for posting it.

Frank would have left by then, although it says 1969 at the beginning it must be 1968.

Perhaps they were checking those too but as you noticed, there's also what appears to be a silver pre-production 'S' Type doing the jumps.

Edit: The "Ranger" RJD 45E was registered in May '67 according to the DVLA database (last taxed in '81), so must have been an early P11A, not a Ranger. Who knows what it was doing there but perhaps it was a factory hack or development bike?

You're headed out to the test track, trying to break a frame that's already killed 5 guys, and figure the proper attire is a pair of bathing trunks? :roll:
Whoa! Who's in charge here?

Those test riders were either nuts or had huge cojones! Perhaps, both were required. Norton owners everywhere owe them a debt.

Interesting bit of history there and it hints of propaganda. It starts with a statement that the boys across the pond used them for road and "rough desert" and that five died.Then you are treated to about 13-1/2 minutes of Commandos doing flying leaps and bumpy road tests. Somewhere, maybe at the end, I would have expected to see a few broken frames but we see nothing - nada.

Granted, I have no idea who compiled the video and for what purpose.

Topic is a bit near and dear to me in that I experienced it first hand. As it goes, a riding partner and good friend back in the day had a Fastback that was quite the rocket ship and he and I on my 850Commando had some spirited rides until one day he pulled it into his garage complaining about vagueness in the feel. We found that one down tube snapped off right at the junction. So there it sat on the center stand with me on it casually letting the handle bars go lock to lock, nothing violent mind you, when the other down tube drops. For some reason he was pissed at me but that did not last long.

Actually it´s an early P11 decernible by the short seat, crossbar and number plate, albeit with the P11A exhaust system, so it´s probably a development bike.

Great to see them setting off from Burrage Grove. Our house was 800 yards from there. I wonder what other films will turn up?
LAB, thanks for posting.

I was going to mention, why not flip-flops?

MY 1968 Commando had the Widow maker frame with some kind of a repair done on the backbone tube. I welded on a steel tube just to be sure. Then I tested it out with cutoffs and flip-flops :wink:

Unless my eyes are deceived by some spell (!) isn't the frame (frames?) carrying a mini tank already braced? If so, maybe the film's intended more to prove that the new frame's safe than anything else?

As I think it can be seen in the picture, the front half of the fuel tank has been completely removed, presumably so the rider could keep an eye on what was happening to the frame.
Various things were tried, such as larger diameter and thicker section top tubes before they settled on Ken Sprayson's brace tube modification, but even then, Norton apparently experimented with tapered pressings welded together to form the top tube and Reynolds were asked to produce some Commando frames to that design, however, according to Ken Sprayson in his book, they were never made and the idea was eventually forgotten.
