I have now put 2 small dents in the side of my Lifan (Which I bought today), as the side-stand doesn't stay down. On normal bikes, the side-stand flicks into a downward state, and stays there. With the Arizona I have, it springs back up if the bike is not leaning over, thus, when I was trying out the kickstand, it flicked up and down went the bike, into the side of my lovely Virago.
The Lifan is second hand, with a couple of modifications done to it so who knows what he's been playing around with.
