K, I gotta chime in here.
Some background: my wife is a police officer. I hear stories, let me tell you... That aside, and being that I'm married to a law enforcement officer, I'm a bit biased.
I have to ask the obvious question - Were you speeding? In all honesty, if you were and the officer caught you, then you're caught. Easy as that. Often times, if a rider wearing a full-face helmet is stopped, they will be asked to remove the helmet for identification purposes. It could be that you have unique enough looking eyes/nose that the officer looked at you, looked at the D/L, and that was enough for them. Officer could also have been short on time, or hurried for another deadline (impending court appointment, etc). I agree with the above statement tho - removing your gloves and helmet before you are asked does show respect, which in turn will earn you the officers respect. This goes a long way - longer than you think.
Long story short, it is the officer's discretion on whether they have enough information (your documents) and if they really want you to remove your helmet or not. I'll tell you from 2nd-hand stories, officers are always nervous about traffic stops - believe it or not, traffic stops are the most risky thing that any officer does. Until credentials have been verified, they don't know if said vehicle is stolen, driver/rider has warrants, criminal history, flight risk, violent, armed, etc... So a "nervous" officer is normal, and means they have good awareness of the situation.
My suggestion to you all: if you get stopped, listen to the officer, be polite, comply. These things may be enough to relax the whole situation, and may be enough for the officer to deem that you are a law abiding citizen and don't deserve the ticket today (remember: their discretion). Now that you have been given the ticket, you have a couple of options:
1) Plead guilty, pay the ticket. Hey, if you were legitimately speeding, you got caught. Consider it the motorcycle tax...
2) Plead not guilty, discuss it in court. If there's considerable doubt about if you were speeding, give it some thought - but it better be a believable excuse... The judges have heard it all.
3) Before your court date, go to the court house, ask to speak to the prosecutor, and plead the ticket down. Not sure if this applies to all jurisdictions, however some (in ours, for instance), you can request to talk with the prosecutor, and they may reduce your fine, and maybe reduce the points on the ticket (maybe). If it was a minor ticket - say 70 in a 60 zone, they might drop the points and reduce the fine to 70% of the ticket.
Please, please, please - and this is for all of you, if you are being pursued by the police, just stop. All too often someone has a "reason" to run - this often ends badly for the person being pursued. Remember, law enforcement officers have radios, squad-mates, and can often draw on other resources like a helicopter. And running over a stop stick (spike belt) on a motorcycle doesn't ever end well...
As well, remember that police officers are people with a job to do. There's no reason for them to be rude, unless you are being non-compliant or rude back. They're people with families, loved ones, etc - and their safety is important, so please consider their safety if/when you are ever stopped. Pull off to a side street in a well lit area where its safe for BOTH of you. Stopping on the shoulder of a busy road/highway/interstate is dangerous, and neither of you will feel safe.
If you broke the law and you get stopped, then you've been caught. How open, honest, even friendly may make your situation better, and you may have legal ramifications of getting caught. But please, please consider everyone's safety - yours and the officers. We all like to go home at the end of the work day - them too...
<getting off the soap box>
I feel better.
