I can assure you some norton atlases DO have fearsome vibration the more you rev them the worse it gets!Norton Atlases do not have 'fearsome vibration'. The vibration they have, is much more than a CB750 Honda at low revs. The Atlas crank is balanced for high speeds. Most bikes are used at lower speeds on public roads. My friend has a Norton Atlas which he used to race in A grade in the sixties against Manx Nortons and hot Triumphs etc. It was and is excellent for that purpose. The 850 motor in my Seeley actually causes the whole bike to rock backwards and forwards while it is idling. What sold the CB750 was its smooth running motor and it's finish. As far as handling and speed are concerned, it was inferior to the Atlas. I rode a CB750 Honda when they were new - it didn't do much for me, and my 500cc Triton made them look stupid in road races. The Honda CR750 was fast, but you had to be a hero to ride one.

I suspect the balancing wasn't top of the agenda at that time
So it was probably luck of the draw what you got?
The 650s Dommies were noted a lot smoother than the 750 Atlas, bigger bores or stroke made them vibrate more???, I will find out when I pull my finger out and get back into building my hot caferacer 650 Dommie but its a ex race bike and the crank has been balanced.
Glad you liked it slimslowslider. One day i'll get around to the sequelThank you so much for this fine, all-revealing piece of historical research, Cliffa
