You're are not the only one who is seeing people riding. I had an officer notice I was riding as well today.
While riding back from work today on my cafe I had a police car pull in behind me and follow me a from near the CN center, up 15th and all the way down tabor to 5th. The light at 5th and tabor was red so the cop pulled up beside me to turn. He stopped and looked at me then drove into the intersection a bit then put the car in reverse and backed up so we were side by side again. Rolled down his window and got my attention.
officer"those look like straight pipes to me"
my internal voice was telling me to congratulate him on his great eye sight and keen understanding of a straight line but my better side got a hold me
I yelled through my helmet and over the earth shaking, ear drum rupturing, clearly deafening purr/hum of my 400CC parallel twin tamed and occasionally missing engine.
Lucky for me my header painted didn't cure where I put in baffles so I had the rust to prove that my bike did have baffling.
He drove of and told me to ride safe.
