I find 5 - 10m in front of the bike is not dipped. Experiments in real darkness as opposed to Hounslow darkness show 2 - 5m works for me without blinding drivers.
Out of curiosity, have you checked yourself what it's like to be the oncoming driver with your settings? I ask because it does of course depend on beam spread etc and my magicshines aren't that tight beam and scatter a lot round the edges - but by the sound of your lumen count, so do yours.
