Street Tracker builds with 19” rear wheels have been popular for a long time (more popular than floorboards certainly). If the basis for the build is a Special (16” rear stock) a problem arises as the stock side stand is about 3” too short with the taller wheel/tire combo (esp. dirt track tires).
One solution that I stumbled across to solve that problem is a
side stand from a 1998-2002 era R6 or R1 Yamaha sport bike. The length is perfect, so only minor mods and welding are required to adapt it to the stock frame. The pivot hole diameter is identical as is that boss’ thickness.
The foot on the sport bikes’ stand is small and sits at the wrong angle, so some grinding is in order to improve that and I chose to weld on some additional plate to enlarge the footprint for softer surfaces.
The other mods required are to relocate the
spring tab to the other side and most importantly a
new stop needs fabricated and welded to the stand to mate-up with the stop on the stock frame (down position). With those modifications made, the set-up uses the stock XS stand spring.
Lastly, the toe catch needs extended so you can get at it with your boot. That modification is accomplished easiest if you just put appropriate size tubing over the existing toe catch and weld it in place. The length and angle will vary depending on the header pipes one runs (mine returns to the frame rail).
