Definitely low-end....but hey, if you like the way it rides......why not go on Youtube and watch some vids and learn how to tune-it-up yourself? It's easy...and you can ride that bike till and if you get sick of it, and it won't cost you a dime. I put plenty of mileage on bikes like that when I was a kid! And the beauty is, after riding that, when you ever get a "good" bike, you'll be amazed at how your performance will jump, having logged lots of miles on the heavier bike.
