Visual Gratification - NORTON Commando 961
The Magnificent NORTON Commando 961: Reinventing Steel
Okay, if you are thinking along those lines, you sure shouldn’t read any further and maybe you can look at some other posts. But now think! Imagine a movie, a Bruce Lee movie or a Charlie Chaplin movie which has been hiding under some dark places and now discovered again and has been digitalized to give a new look. It is not a new movie, it is an old movie but you know, it has got the digital treatment, say bright colours, better sound and all. And now think of the new computer generated blockbuster movies like 2012 or Matrix or the likes. Which movie would you prefer if the ticket costs are also equal? If you would go for the Charlie Chaplin or Bruce Lee movie, than you know why Norton can afford to make a 80s bike now. This is a Norton, period. You know MV and Ducati will keep on churning out brilliant bikes in the future just as Hollywood would keep on giving blockbuster hits, but what are the chances of you getting a hold of a rare Charlie Chaplin or Bruce Lee movie?
And you know what? This Norton is just too damn good, we will get to the too damn good part, what I mean is when you talk about something like Nortons, you don’t talk about money. Okay, if you are still reading the post, I believe you are a sucker for British bikes like me and so now we are on the same page.
Norton is by far the most historic and famous brand coming from the land of the Queen with due respect to modern brands like Triumph and legends like Vincent and BSA. Although it never would have mattered which motorcycle Norton relaunches, but we are oh-so-thankful that it is the greatest bike from the Norton stables, the COMMANDO.
Watch the videos slowly and repeatedly. You will keep on falling in love all over again. I have… I have. Have you heard its voice? Oh… the legendary exhaust is back. If you think I am overdoing it a bit, then I am probably because I have not seen many legends being resurrected. Quite often, there have been talks, but nothing finally happens. And now that finally something has finally happened, it is time to rejoice. The first video is a Norton home video and its DVD is available free here and the second video posted here is covered by MCN, a British magazine which maybe partial to the Norton being a British bike. Good, because it is much better than a critic who would probably laugh off at the beauty comparing its price to what it is offering.
As you see it, this is a classic, so you won’t get the ‘equipments’ and good for it, it stays true to the memories. The Norton motorcycles were always naked and the tradition continues with no plastic fairings of any kind, no luggage carrier either, just muscles and bones, a true show-off!
The new Commando has the original authentic appearance and a mechanically similar general concept for its vertically split, air/oil-cooled dry-sump engine, with its forward-canted cylinders, pushrod valve gear and two valves per cylinder and so carries forward virtually every trait of the original including the authentic Smiths look.

Mail by Paul Wilson
Mail by Joe Schome (abridged)Hello,I was just looking at the pictures of the cafe racer, described as a 650ss project. I'm a lifelong fan of the featherbed framed Nortons and can give some information, based on what can be seen from those images.The rolling chassis appears to be Manx Norton. Definitely not 650ss. The Manx frames were made from Reynolds 531 tubing with brazed joints. The diameter of the curves to the upper rear frame tubes are Manx profile.
The forks, swinging arm, wheels and gearbox could well be Manx. I'm not sure about the front brake plate; but it does look like a nicely made item.The camshaft breather type is either Atlas, or early 750 Commando. The engine is most likely one or the other. Not 650ss. It looks as though there is a Manx type primary chain oiler, with the correct type of reservoir in the left-hand top frame tube. I didn't understand what you meant by: "....Commander crank-piston-air vents". but realised that you were referring to the cylinder fins (inclined on Commando; but horizontal on Domi/ Atlas). You can use different engine plates to achieve either with any Norton twin. The cylinder barrels look as though they are aluminium alloy; so may be another bonus with this project, assuming they are well made and in good shape inside. The Wal Phillips 'fuel injectors' are not bolt-on-and-ride-away accessories. They would take a long, long time to set up properly. Even then, they were designed for flat-out, short-track racing and would be a real problem to ride with for any more than 10 minutes!
Whoever made the saddle has never ridden a 'wideline' framed Norton! This could be a real good special; but will need a hefty wallet to finish it nicely.
Regards, Paul (Devon UK)
The front brake IS Manx. Not all year Manx bikes had primary chain oilers fed from the frame, some years fed them from the oil tank, so that is not a reliable method to throw out and say "that frame is a Manx or that is not a Manx", besides, anyone with any fabricating skill can add or delete frame features at will. ...if you look at the photos closely you can see that someone went over the whole bike with #1 a bead blaster, and #2 a spray-bomb of silver paint. Notice how the tach drive and many other alloy parts look "frosted", nothing on the bike has it's stock "as cast" finish. Notice how there are no nuts holding the cylinder barrel on, bolts holding the head on, no springs on the rear shocks, No tach cable, wiring or fuel lines or cables. Bits of silver overspray here and there. Contrasting this someone put a seat on with new
upholstery.Yes there are a lot of Manx bits there, but they are beat ... and would need to be gone over by a real engineer. The cylinder is Dunstall, but Dunstall made 750 and 810 cylinders, so saying it is probably one or the other is more shit-talk. Also, Dunstall and the Norton factory, and other tuners put fittings and lines in the exact same location that the 750 Atlas breather fitting was to feed oil to needle bearing camshafts... I have been around Brit bikes ... do you want me to talk about having a featherbed Manx and at least one example of every model Norton dominator made since WWII?
Correction on a previous NORTON post
I had made a post of a NORTON 650SS restoration or so that was what I thought. Today I got some mails from Mr. Gary Parker who is the Canadian representative for the International Norton Owners Association stating that the mentioned bike is actually a Norton Atlas 750. He had justified his statement through his mails. When a person of his stature has confirmed about the Norton, than I guess, we can rest all doubts about the model. I got quite a few mails with the queries surrounding the mystery of the bike. I guess the following mail from Mr. Gary Parker will restsHello there, My name is Gary J Parker, and I am the Canadian representative for the International Norton Owners Association. The bike in the photos that are posted on the "Visual Gratififcation" blog are of a Norton Atlas 750. They are NOT from a 650SS or a Commando. There are a number of ways we can identify this.
all doubts.
1) The engine breather on an Atlas (and very early Commandos) exits the engine on the front drive side, off the end of the camshaft, whereas the 650SS engine breather exits the engine at the REAR of the drive side crankcase. As you can see from the photo of the drive side, there is an angled pipe on the front drive side which eliminates the possibility that this engine is a 650. That area would be bare if this was a 650 engine. The pipe is almost uniquely Atlas.
2) Commando top end oil feed is from the sides of the head, between the rocker spindle cover plates, google any image of a Commando and you will see the oil feed in the space between the spindle covers, whereas the Atlas has its oil feed from the top of the head, on either side of the head steady. On your engine, the area between the spindle cover plates is bare, indicating that the head at least is not a Commando head.
3) Your engine has a tach drive, which only the very earliest Commandos were fitted with. 4) Interestingly, your bike is equipped with a "Laid down" Norton gearbox, a design which was changed in 1956, all later Norton twins were equipped with the AMC gearbox, which continued till the Commando. For reference, there were no 650 or 750 motors being built by Norton in 1956. This box is from a much earlier bike.
5) Another interesting thing is the cylinder block, whch is not stock Norton, the fins are too few and spaced too far apart. This cylinder block is in all likelihood a Dunstall kit, bored out to 810 cc. It is DEFINITELY NOT Norton, but aftermarket and desirable. Paul Dunstall marketed "Go Fast" goodies and tuning kits back in the late sixties and early seventies.
Any more questions i would be happy to answer.

Well, I also thought that it may be a Commando, but Gary has very clearly put that it is not. He sent some more proof in his second mail.More: Looking again at the pics, i have come to some conclusions. This bike was originally an early to mid fifties Norton Dominator or single, in all likelihood a bike which had a catastrophic engine failure. The frame and all cycle parts are too early to be Atlas (Or 650SS for that matter)
the frame number (Located on the metal flange which is directly behind the primary chaincase) will tell a great deal but the frame is quite early, I would say 53-55, and may even be from an International or Manx OHC single. It is definitely "Wideline" or pre -1960.
My conclusion, a long time ago someone with a wideline Dommie or Inter blew their engine up and found a mid sixties Atlas with a Dunstall big bore kit and plumbed it in.
cheers, Gary
PS search for frame numbers and engine number is on front drive side of crankcase just below barrels.
I am very familair with the Norton Dominator/Atlas/650SS/Mercury series of bikes, I own two and have restored a couple more.
cheers, Gary
I recieved another mail from him with his final thoughts.OK, More conclusions. Sometimes it takes quite a few looks to get familiar with something. Some things are obvious, some things must be inferred by context and "Feel".
Engine: 750 Atlas engine, 1963-68, fitted with Dunstall overbore kit, possibly 810cc. will be stamped thus: 20 xxxxxx or something along those lines, followed by the letter "P". Possibly stamped N15CS xxxxxx (xxxxxx indicates actual serial number) If the latter is the case, then the engine, while identical to an Atlas, came from a Matchless/Norton hybrid scrambler, made between 65 and 68.
Gearbox: pre '57 "Laid down" Norton box, 4 speed. Carburetion: Wal Phillips Fuel Injectors, rare nowadays, period aftermarket "Go Fast" goody commonly used in the sixties, difficult to find now.
Frame; Looking more and more like a Manx or Inter OHC single frame, the key is the curve to the rear of the engine, the twin frames had a tighter bend, frame number if found will tell. Definitely pre -1960 which eliminates as noted any likelihood of it being a 650SS. This baby is a true "Bitza". Frame number, as previously noted, will be found on the flange to the rear of the primary thus: 122 or 14 or something like that, the 122 if present would indicate a Domi 88 500cc, the 14 indicates a Domi 99 600cc. These are model deignations, the actual serial numbers follow. If the frame is a true Inter or Manx, instead of 122 or 14, the horizontal number will be either 10, 10M2, 11 or 11M2. Let me know what you find, I'm curious. The frame, although early, is not TOO early, being post 54 as the rear section was bolted on prior to that, not welded as in this case. The shocks are Armstrong, not Girling, so mid fifties is what I'm thinking. the rear brake has been heavily altered and may not be Norton at all, it has a bolt on sprocket, which Norton roadsters didn't have at the time. the front wheel (Or at least the hub) is conical, possibly Manx, but there is also the possibility it might be late Triumph, but I'm betting on Manx or International. The front guard is Inter or manx pattern.
My conclusion then, the bike was a racing Inter or even a Manx (again, without numbers it's very difficult), the engine blew or was removed for some reason, and a modified Atlas engine was installed in its place, complete with the Wal Philips rig.
you have a very interesting and unusual bike here, rather a bitza but a good one. Incidentally, the bike in the background in the picture of the timing side is a 57-59 Dominator i think but it isn't clear enough to tell.
cheers, Gary
The third letter had me dumbfounded. There was no question of doubt even after the first letter, but the second and the third... the third was actually too technical and a lot of things flew over my head. I read it thrice, still... I could only capture some ideas what Gary was saying. And I am sure lots of us will feel the same.
This man is a genius on Nortons, what an amazing amazing techno person. Any person on earth having any doubts on his Norton can mail him at atlas65@shaw.ca and I bet even if you have a mudguard from a Norton, Gary will be able to recognize the model!
Thank You Gary, you are amazing... REALLY!
Before any gentleman get to having second thoughts on certain things Gary had mentioned, please note that his comments are guesswork based on experiences with these machines. After reading the post, he specifically mentioned to add a few more notes to clarify things.

JAMES ML125 & NORTON 650SS - Restoration
I recieved a mail with these photos and absolutely no text at all. just the attachments. it came from a gentleman from Brazil, that i got to know from the email pituco.com@uol.com.br. All the images came under the name of Navio Motors. A frantic search on the google for Navio motors ended up in a possible link which was directed at Flickr, but the link had no motorcycle images. Pituco.com also was kind of a dead end.
Okay, I got another mail from the guy who actually wants to buy this ongoing restored bike but he is not sure if it is the NORTON 650SS. The frame definitely is from the 650SS. The engine... to what I feel can also belong to a Commander as the Commander crank-piston-air vents are slightly inclined than the more straight 650SS. But then I could be wrong. Anyone with any more insight? Email pituco.com@uol.com.br or diesel@aol.in
