losing the back under front braking...sometimes?

[Val]

Just a thought, are you changing down as you do this?, the rear will lock up quite easily due to the strong engine braking.

Nope I rarely do that. If I change down usually I don't use the brake until last few meter before stopping, because the engine braking is very strong on MT09.

That happens only when I need the brake - something happens and I need to use the front brake in a sharpish way.

Update today I was overtaking few cars with 70ish or more and I was in the opposite lane while doing that. The lane was straight and free more then 500-600 meters ahead. A car has popped up from a driveway in front of me in the lane. Luckily there was enough distance. The front brake was pulsing hard at the lever when braking from speed and the whole front was jumping like going through speed bumps.

Any ideas?
