It is the only kit I could find. I would probably build my own somtimes. The suspension is not very easy to hook up as the washer is between the handle and the upper part of the suspensio). The windshield works great, but not surprise there (look at the price). The handle is comfortable.
My only real concern is with the suspension system, that is not particularly easy to set up. I've had this for 2 years (I think), and nothing broke or aged badly so far.
