Zx14...opened box to bags n bags of small parts...yikes. Most of the work is in the area of the left rear side. Removing and installing a big lift handle. The actual install of stand is basic n easy...2 main bolts n a spring with 2 smaller bolts attaching a spring catch for the front of spring...oh and of course removing exhaust...probably took me three hrs.going slow and being careful. The down side to installing a rear stand is u must place a rubber stopper on factory exhaust attached to an already there flange with corresponding hole...otherwise stand with press up against bottom of bike without the stopper and ride against the chain till it's destroyed. Unless aftermarket exhausts have this feature to allow install of a stand stopping mechanism you can forget about installing aftermarket exhausts and also having a rear center stand. Wished I'd known this up front...been looking at all the exhausts available.
