Today around 7:30pm my son, who is 3 and rides a KDX50, asked me if we could ride our motorcycles in the yard. I have two bikes, a YZ250 two-stroke and a TTR-125 four stroke. Now for obvious reasons I chose to ride the TTR in the confined space in our yard. Shortly after we started riding our neighbors came out yelling and called the police stating that we were out there riding for the sole purpose of annoying them, which is obviously not true. We just didn't have the time, nor did we want to load up the dirt bikes the the trailer. Anyway When the police arrived they said that we were within our legal rights to ride on our own property but then after they talked to the neighbors in person they retracted their statement and said that they have legal grounds if the sound of the motorcycles are bothering them. Now my question and my concern with this entire situation is that my son's motorcycle is only a 49cc bike that is half as quiet as a weed eater and my ttr which is no louder then lawn mower. Have any of you had this issue with your neighbors, what did you do and does anyone know if I can really legally be charged for riding on my own property cause I know I couldn't possibly press charges on my neighbors at a reasonable hour for them mowing their lawn simply because the sound annoyed me. If I really was out to annoy my neighbors I would have taken out the 250 What are your thoughts...?
