Why does the system actuate if the rotor is not moving? When stationary and apply front break pressure the RG vibrates..this is my first Harley with ABS. It is annoying...

 

I would say thats an anomaly, mine doesnt do that.

 

If your analysis of what is happening is correct, something is wrong. Re-read your manual, the ABS is disabled below some very low speed so that the brakes will work when not rolling. Some people have reported an increase in vibration at idle when both the front and rear brakes are held while stopped. The frame is partially inhibited from absorbing some of the engine vibration with both wheels locked. If you hold both brakes when stopped, this might be what you are feeling. Does your ABS light come on when this happens?

 

just pressure on the front brake, no light activated.

 

That would be the vibration of the motor that you are feeling. When the front brake is not applied, the vibration in the front fork is minimized because the wheel rolls back and forth slightly. When you apply the brake, the wheel can't move and thus the vibration is transferred up to the handlebars. This is normal.

 

^^^ Exactly. Mine does this as well. Has since new. A non-ABS bike does it too

 

I had not thought of that, but I am sure you guys are on to something. The OP should shut off the bike and see if the problem continues.

 

...i don't feel it in mine, but then i try not to sit with the brake activated if i can help it. said to contribute to the warping of the rotors
