Changing My Counter Sprocket

I have a 2007 TTR 125 with a 150cc big bore kit. It currently has a stock 13T on it and I want to change it. I'm thinking about putting a 10T on it, and I've found many that fit but most of them say they're for pit bikes. Is it a bad idea to put a counter sprocket this small on my bike?
