I ride a 1000cc sportsbike and drive a bright yellow Stagea (and a black R33 before that and a bright orange and rather loud 180b before that) and haven't been "harassed" in over a decade.
Strangely enough, the only time I've ever been "harassed" is when I was driving like a f**k wit, apart from maybe twice where I got caught in an RTA/Police operation in Lismore on Cog night. But then I should have known better than to be in Lismore on a Thursday night. So in about 17 years of driving obnoxious, loud and fast cars and bikes, generally well above the speed limit and without really giving a shit what anyone on the road thinks, I'd say twice I was "harassed" by police. The other 4,385 times I've been pulled over were fair enough and I was likely driving/riding like I deserved it.
The moral of my story? Stop driving like a f**k wit in places notorious for being f**k wit attractants and the police will leave you alone. There is no conspiracy. You're young and you drive like you think you're Fangio, or you hang out in places you think chicks hang at, where as in reality only other guys hang out (make of that what you will). You'll grow out of it one day (or at least learn to pick your times and places) and almost like magic the Police "harassment" will stop.
