I remember posting a question a while back wondering if the Empulse would trigger inductive loop sensors used at stop lights and the IL Tollway due to the amount of conductive metal used int he motor. After two and a half solid months of going through two toll booths every day I have been charged a total of 0 times. That's a better record than I get with my all-aluminum SV. It's possible a few months from now I'll get a slew of picture tolls, but usually they catch up after a month. So the moral of the story is that the motor won't trigger the sensors. The motor must be shielded to protect the nearby electronics, and that blocks the sensors from picking up the bike.
On one had that sucks for people that need the bike to trigger stoplights. On the other, it lets cheapskates like me not pay tolls.
