Sounds reasonable. None of those parts are technically challenging to install but is does take some time to put all of that on. The $140 labor is a fair price. The only thing you might have problem with yourself if you're a novice wrench is a couple of bolts for the skid plate that hold the sidestand mount and then getting the spring on the center stand. If you do the crashbars, only loosen one end of a motor mount at a time.I've decided to keep my 2008 wee. I'm in need of and have priced the following:centerstand ($170), crashbars($160), skid plate ($220) plus ($140) installation, totaling $717. Too much?
