I've only own a '98 Tomos Targa LX and its my first and only moped. I am very pleased with its performance and has been running great for me. People say they are getting 45mph out of it with a Turbo muffler, larger jet and a 27 tooth sprocket. I can only get 38mph out of it (after I put these parts on) and 40mph crouching down to the bike (both speeds are if the wind is blowing at my back or no wind.) Fast enough for me!
