The front fork stem requires an 8 mm head pin for a triple tree stand. While a machine shop could easily take a 13 mm pin (which is the smallest stock pin I can find) and trim it down to fit, that would involve some money. I think there is a simple, effective, and no-cost way to raise the front wheel of the Zero if you need to replace the front tire for example. Here is how I would do that: First, I would use the rear stand to raise the rear wheel as I have shown. Next, I would place a 2 by 4 under the center frame support but more toward the front. Then I would place any floor jack...a car jack would do...in the center of the 2 by 4 and jack up the bike until the front wheel was off the ground a couple inches. Finally I would place additional pieces of wood , blocks, anything strong really on both sides of the jack out toward the sides of the bike, and lower the jack slightly so there was only passive pressure from the jack on the 2 by 4. Now you have support on each side of the bike in both the back with the rear stand and on both sides toward the front with the 2 by 4 wood plank. This should allow you to remove the front wheel.
