I know some people have said its NOT the ABS, but I disagree. 43k miles into owning mine and I have noticed this exact same thing, only when at low speeds and only on occasion. Mostly it happens to me on my commute when either there are damp patches and I'm coming to a stop, OR I hit some painted areas, OR I hit some slight dirt/gravel, or metal, or oil, all of these scenarios while coming to a slow stop.
It's never consistent and it almost always happens with cold tyres and cold brakes in town, never at high speeds
