A simple complaint of a motorcycle speeding might be insufficient; however a complaint of a motorcycle speeding on a specific roadway in a specific direction along with a description of the bike and rider along with an estimated speed is probably adequate to justify some investigation, especially if the driving approaches a level that might be criminal or could be suspicious beyond a simple traffic violation.
That is true. I was thinking about cases where a person was stopped without strict probable cause (pc) and arrested
on one or more charges. In the case I'm thinking about it was shown that the officer's pc was defective and the charges were dismissed.
I do see your point for justification in making the stop, though.
