These are really well built machines - my 2005 P250 has over 28,000 miles and still runs both efficiently and strong. Like most pieces of modern machinery, if you take care of it, it will take care of you. The only real problem I had was with the Kenda tires which came on it. They were hard, slippery and developed a crack on the rear at about 6,000 miles. I replaced them with Avon Viper Venoms and the world changed! When I smoked a few sport bike riders on a twisty road in Wisconsin, it proved the point to them and made my day.
Good bikes Kymco ... change the oil, check the tire pressure at least weekly and listen to the engine and drive train at least once a week (without your helmet on). That is the early warning device.
