Well, first off, can you please post all pages of the PCN, and the right way up so we can read them without getting a stiff neck.
Can you appeal it ? Yes of course you can, and have the inalienable right to take them all the way to London Tribunals if necessary, but winning an appeal is another matter entirely, hence our request for the full PCN.It would also be useful if you can post a Google Street View link telling us exactly where the contravention occurred, i.e. more info on what happened to cause you to get a PCN.
Edit
The photos appear to show you turning right and then passing what is called the "Flying Motorbike" sign, (bike above car symbol). This sign means No Entry for motor vehicles, but there may be a sign below with applicable times.
