Can I fight this speeding ticket?

Pay it. I don't see why a judge will look favorably on you. Lets start at the beginning of the day. You got on a motorcycle which you weren't license to operate. Strike One. You speed more than 20 mphs over the speed limit. Which most states would add on a reckless charge. So Strike Two. On top of that you ran a stop sign. Strike Three. Pay the ticket.

If it is your first ticket (Your license is clean) hire an attorney. He'll get it reduced to a non-moving violation without a problem. It is not the cheapest way, but it will work. You could appear yourself, but the deck is against you. The cop schedules all his tickets for the same day of the month, and unless he blows all of them off, he is going to show. If you go that route, you better have some legalese to spout at the judge. Things like asking for proof that the gun was in calibration, that the officer has had certification/receertification on that model, etc. A lawyer knows what all these little things are. And they have to be able to produce them. But if they can't, the judge will probably grant a continuance til a later date so prosecution can produce them. If it is just you, the prosecutor will keep this up, and it will drag on for a long time, and again the deck is against you. But the prosecutors and the defense lawyers all know each other, and rather than go through all that the prosecutors will just offer the defense attorney a deal to spare all the BS. Quick word of advice: Paying a lawyer sucks, I know, but it is worth it. It will get handled right. You should fight every ticket, because you never know when there will be one that you can't get out of. And they usually stay with you for three years, and if you have a blighted record, they are more apt to slap you with the next one. I'm a trucker, and I've had a number of tickets, and I take no chances with my license, cause I need it to make my living.

THE COP SHOULD GO TO COURT

YOURE LUCKY

YOU WENT 91 AT A 65 ZONE THATS ALREADY $200 FINE

YOU RAN A STOP SIGN TAHTS ALREADY $50 FINE

AND YOUR LICENSE WASNT EVEN REGISTRATED THAT A ANOTHER $80 FINE

WOW YOURE ON CRACK

Firstly, you should have been charged with reckless operation since you were over 20 MPH over the limit. I feel safe now since I don't think I need to worry about you being on the roads for a while though. Hope your wallet is as thick as this reasoning.

You went 90 mph through a stop sign on a bike? You're lucky you weren't arrested. Or killed. That cop gave you a huge break.

bad idea since the cop has you on two other charges dude. just pay the ticket and save some time.

Yes, please do. The "I was so distracted that I was not watching what I was doing" defense will get you exactly what you deserve, the maximum penalty possible.

lol dude that was pretty funny. seriously though , you are not getting off.

you should pay your fine and do things legally like you are supposed to and you won't have these problems

Just pay it, or you'll be getting yourself into deep sh**.
