Cylinders can be made to fire anywhere in the rotataion according to ignition timimg. Check out the firing order on the Yamaha Cross plane "big bang" engines sometime

I had 3 Yamaha XS 650 twins 73, 79 and 81 and they were indeed shakers. You could walk them across the garage floor by revving them up on the centerstand. Loved them though. I never saw the Yamahas crack fenders or lic plate brackets or loosen and have parts fall off like I did the British twins though.
I also had 160, 305, 350 and 450 Honda twins and a 03 Triumph Bonneville twin. The Triumph with the counter balancer was amazingly smooth. Smoother than my V65 longitudinal V4 Honda and my V4 transverse ST Honda.
