As far as I've been made aware, if you are going to court for the ticket it will not show up on record. If you lose and are convicted of the charge, then it will show up. So, if the insurance company asks if you have any convictions, assuming this is the only one, you can say no since it still has to be decided in the courts if you're guilty.
I'm wondering if I should buy the bike pay for insurance now since I don't know what the outcome of my trial is going to be.
Well if this is your first ticket, it will make little to no difference in your premiums depending on your insurance company. If this is your 2nd or 3rd ticket in the last 3 years, you may have issues (Once again depending on the company).
