Rear Brake 'Pulsing'

I replaced my stock brake pedal with Kuryakyn's extended version - more comfortable and better quality. However, on a brief 10 mile test run I could feel the master cylinder pulsing, as if ABS was activating, even though I was only braking gently. As the ride progressed, the point at which the pulsation started seemed to change and eventually almost disappeared - no warning light illuminated. Is this something to be concerned about; does ABS have some sort of self-calibration for the new lever dynamic and it will settle down after a few more miles? (2015 SGS).
 
How fast were you moving when the pulsating was happening. If your over 20 to 25 mph your front and rear brakes are linked together. Could also be feeling more with the new pedal that was there before with the old one.

If I’m not mistaken, the ABS doesn’t kick in until over 25 mph also.

ABS braking system is an electronically linked brake system. Front and rear brakes are dynamically linked through the electronic ABS module. "Linked" means that both front and rear brakes are applied at the same time. Electronic linking provides maximum braking for all riders while allowing the more experienced rider flexibility. Braking is more responsive and allows more balanced braking under a wider range of condi- tions.
• ReflexTM Linked Brakes is designed and tuned to provide a seamless and predictable braking response.
• Linking is electronically controlled to achieve an optimized brake balance based on the amount of brake applied and vehicle speed. The amount of linking is dynamically adjusted to provide maximum benefit in heavier braking and is reduced or eliminated for light braking and low speed.
• Linking can occur in any braking situation above 20-25 mph (32-40 kph) whether only the front brake, rear brake, or both brakes are applied.
• The amount of linking is programmed to provide a good balance of stopping and rider feel.
• Front and rear brake systems are still hydraulically inde- pendent.
• If an ABS event occurs, the ABS unit will pulse the brakes to help prevent wheel lockup.

Thanks for the feedback chaps (UK speak). I'll have a run out this weekend and put it to the test. There's no technical reason, that I can think of, so maybe it's just me getting used to a different leverage point with the extended pedal.
