Do you really have to be 100% honest with your motorbike insurance company?
I think you need to be guided properly on insurance claims. There are many disadvantages of not reporting some damages that your bike encountered and you have cited some of them. So what is the point of not telling them? They will find out anyway so you might as well report these incidents to them. They may be helpful in the future. I suggest you talk to cycle claims to learn more about insurances on bikes. These consultations are completely free and you need not worry. A professional and expert on bike claims will attend to you as if you are a paying client. This is a service they offer their new clients.
