I definitely get more attention from law enforcement when I'm on my sporty-looking, red GTS1000 than when I'm on my GS. Wearing leathers instead of textile gear pushes things up another notch.
On the red thing - my brother used to be a cop in UK. He told me once that traffic police would occasaionally play "snooker". For those not familiar with the rules, you basically have to get a red in between every other color. In real snooker black scores highest but in traffic snooker, pink was the highest due to rarity. Red cars were therefore under scrutiny more often than any other colour, and if you were in a pink car when this game was going on you were going to get pulled over no matter what. White or silver cars were of no interest.
