As the Guy officially not in charge. Of the motorcycle tag, of course you can!
I'm actually jealous of your cbr-125. In the US bikes that small were not available until just a year or two ago. I'd lobe a 125 for putting around on and also for getting great gas mileage. My bike may go fast but I can barely pull 40miles per gallon.
Welcome aboard, and keep the rubber side down and the shiny side up.
