I'm new to motorcycles and this may be a newbie question, but I figured I'd asked anyways. When I pull my clutch in (in first gear), the rear wheel still moves. When the bike is in neutral, the wheel doesn't move and shifting gears seems to works fine. If I apply to rear brakes for 10 seconds, the wheel stops moving, but once I hit the friction point again, the same problem occurs. I was wondering if anyone knows what might be causing this? I hope my explanation is clear enough.

Thanks for your time.
