I have heard good things about the Demon X pit bikes and when I got mine I wasn't disappointed. I'm new to the pit bike scene so I went for the Demon X DX110cc to get me into it knowing that I could upgrade with a bigger engine and better spec suspension later but the frame and swing are the same for all their models which is what I wanted. After using the bikes for a few weekends now I'm quite happy with the power of the 110cc lifan engine and at my level of riding will probably just stick with this engine for the time being. They only bad thing I can say is it looks so cool I don't want to get it dirty. My mates are selling their pit bikes now to get Demon bikes lol Peter Smith
