One thing I've noticed over the years is a Norton's vibration RPM points and just vibration in general is all over the place depending any number of variables. On a nice cool day with elevated humidity a Norton seems happiest with minimal vibration at any RPM. On a warm day vibration RPM points and magnitude float all over the place, or it seems to me! :lol:
 
Nahh!
Mine vibrates nicely at 2500rpm, everwhere else ain't bad.
 
With lightweight pistons - everything is smooth. The sun always seems to shine and the rain and cold doesn't bother you.

Vibes!
 
In my opinion, Norton Commandos are contrary, cantankerous bastard things and they directly reflect the mood of the rider which is why they can be Oh-so-wonderful and intensely irritating on the same trip. Mine shakes more and handles worse once my shoulders become tired and stiff at the end of the day.
 
Smooth flying is by far the most important Commando feature that keeps me interested. Next is the Supremo Handling I've found possible and just a hair less vital to me Craving Commando under me. Ms Peel had both and flat disappeared from pilot sensation. I'm trying half her set up in Trixie by getting her chassis straight enough for alignment and clearance to assemble w/o truama-injury and trim front iso's to almost one half the rim thickness via bench grinder. But of course engine set up and balanced tune matters too. There is a whole another level of jiggles-jostles and vibes that have Nothing to do with engine even turning in bike, just from all the slack in various areas that road pilot and wind induces but is sensed as normal until full rods eliminate it for uncanny sense of huge loaded Goldwing inertia smooth.

Its also educational to take cycle air borne for a second or so and feel how suspension and isolastics and bike mass concentrations inter react w/o the complexity of road loads. Peel feels like loose biplane wings and propeller till she lands on rough Gravel-Pasture again at speed. My other bikes just the opposite. Flabbergastingly Fabulous. You can also study effects of wheel and crank gyro's to discover their contributions to stability or extra momentum to control or avoid.

W/o full rods and combos on-off / tight slack, its got whole motorcycle industry confused on what is doing what as everything so splish-splashy together. Ms Peel isolated every nuance of notice to its obvious source but was essentially transparent to them, passing them through w/o bothering anything. Flabbergastingly Fabulous!

Also level-interval of loads by power, lean &/or bumps can also eliminate some annoyance and if loaded enough w/o crashing - pluz can isolate phenomena into spearted contributors instead of combined to hide real interplay. Flabbergastingly Fabulous

More $$$$ fixes everything! :D
 
You could even buy a smooth 6 cylinder BMW Bob (Oh dear!) :oops:

And BMW found a way to put their 6 cylinder in a bike. My sons still driving my old BMW 328i 6 with 290,000 miles! :shock:

BMW are bringing out a 6 cylinder K1600GT bike.

And it's the same width as a 4 cylinder inline. Gonging to be pricey tuneup! :roll:
 
Smoothest of all is the Norton rotary/wankel.

If it would just burn clean.

Pretty sure if you put your hand by the exhaust it would get burned clean off. :mrgreen:
