I've only been able to find this reference, "rocker arms have a leverage ratio of 9 to 8 - a factor which reduces inertia loading"

Not sure if this means 1.125:1 or something else? Thanks

Nick,
I am not claiming that my Atlas is as smooth as my Trident or my Velo, just that a balanced one is not as bad as its reputation. I got mine in a basket and it was probably pretty bad from the factory. The insides of the speedo and tach had disintegrated into mush. I regularly run my bike up the rpm range and I have never gotten the handlebar vibration you are referring to. I have a few friends with Atlas's. One is a vibrator. The other one is not.
