Bikes are not like cars where you just drive them until the wheels fall off.   A motorcycle is a high-performance machine subjected to more vibration and other adverse environments, and you need to check fittings, fasteners, tire pressure, oil level, chain lubrication, and other things on a regular basis.

If you'd like to see the recommended checks for RX3 chain and sprocket maintenance, here's a blog we did on that topic a ways back.   And here's a video with Gerry explaining things to check on your TT250 before each ride.   The concepts are the same for the RX3 and RC3.
