I used to buy Motorcycle and Motorcycling in the 1960s. They did not tell me much. And I don't speak or read Italian. That is where the real motorcycles were made.
I was offered a genuine Aprilia 250 production racer but I did not appreciate what it was., My friend raced it against a fast 250 AIR Kawasaki and was right up there with him - the guy who held the lap record at Calder Raceway.
 
Back in the 1960s, very few people shared information which could make you go faster. Theoretically you could build a race bike which was faster then the works racers, These days it is different, no privateer is going to build a bike which is quicker than an R1 or a Fireblade. That is why classic racing is better than racing moderns. I don't care what anybody knows, if I can help them to go faster, I will just have to ride faster.

Id be worried if I was ' obsessing ' about stamped out two bit toy ones .

we Must've missed the Norton commando's 50th Birthday Celebrations . ! ?
Its only about 30 years younger than a SPITFIRE or HURRICANE .
The Spitfire aceptace test was all out climb to 20.000 feet , ( or whatever ) trim check , full speed dive etc . they seldom ' let go ' .
So this ' unreliable old trash ' epitah is rather drivle . The POTENTIAL was often nullified by neglect incompatace and ignorance .
http://www.spitfireperformance.com/spittest.html antiquated geriatric irrelivancies . ( they tent to give the veterans ful stick in NZ )
Post 60s stuff was not neccesarally designed for a Anual ' De-Coke ' , so SERVICEABILTY was a Pre Requistte then .
Also Harley Davidson wasnt stupid enough to believe the insolance and abuse of the ( bribed - how unusual ) inebrite press ,
on their machines antiquity , obsolecence , and irrelivance .
they dont seem to be doing to bad , with their third ? generation redesigns of their Original Concepts . tho we worrie about the new lot at the helm . they seem to be discarding H. D. Signature Componentry .
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As far as our antiquities , in ' Their era ' the snaps prescented ( of Commandos ) are Period of the TOP LINE outfits . Id assume anyone ignorant if unfamiliar with their results . ( Could always put the Tri one on )

Your's for $ 7 . an Original renior . or you can have a Print for 20 quid .
On TRACK . back then .


At one stage , Triumphs ( and Nortons ) were made by highly skilled master craftsmen . When they wernt on the turps . Current stuffs stamped out all the same , like jap stuff .
Hence one is appaled at people blowing up and wrecking 50 year old irraplaceable ORIGINALS . Racing for kicks theres plenty of cheap trrash available .
If you want to set up a original Norton or Triumph , DO IT RIGHT . Or dont blame the bike for your ignorance or ineptitude . And dont butcher it . A lot ' non stock ' are better .
And some nit wits restore them to ' off the shelf ' and then sit them on one . History destroyed - for the sake of a conversation piece .

World Champion follows P W , 750 Hemi Head Combat , Reworked Stock Chassis . 155 mph .

On TRACK . back then .


Bottom Left . The Commando Short Stroke Hemi , Combat Cam with 1 m.m. off the Base Circe . ISOLASTICS . Beat All Comers at the I.o.M. F-750 ( Before Yamaha screwed the PRODUCTION BASED Race Class )
and before the took all the lumps & bumps out of the CIRCUIT . So THEN it was a test of the ultimate Road Holding . Whereas now is of the riders lack of sanity & depth of wallet .
On TRACK . back then .
 
Of Course , These things held the World Motorcycle Land Speed Record ( and many class records ) for years . Thrown together from largely STOCK Triumph Componentry .
And STRONG enought to STAY TOGETHEr if assembled by competant and carefull fitters / tuners .

On TRACK . back then .


Of course these old dungers only did about 10.5 rpm & 160 / 175 mph .Aron slight , who obviously wouldnt know anything , thought better to ride than Soichiro's finest .

On TRACK . back then .


Theyre so Heath robonson , anybody'd be advised to give em a Wide Berth .
On TRACK . back then .


And as for these , anybody'd STAY WELL CLEAR . THEY VIBRATE SO MUCH HALF THE PARTS'VE FALLEN OFF IN YOUR DRIVEWAY . BEFORE YOU EVEN GET TO THE LETTER BOX .

On TRACK . back then .

When you build a four-stroke race bike, you make a choice. You can get more power by revving higher or you can increase torque and use different gearing and end up in the same place. If you choose to rev higher, you need a cam profile which has gentler lift and closing rates, and less total lift. When Norton used the Combat cam, which path did they choose ?
 
It was a new model for the times like ag bikes that had the lever for hi and low ratio gearing, flick the switch for 4 or 2 stroke as well for smoke screen and rotten gas fumes.

Some of my mates, back in the day, didn't need the bike to make rotten gas fumes. They were pretty good at it themselves! But not me!;)
