I have a pitbull rear stand and vortex swingarm sliders. My question is how much weight can be put on your bike when it is on the stand. For instance could you sit on your bike when it is on the stand. I ask because I just signed my mom up for the riders edge course at the harley shop, but it starts in about 3 months. In the mean time, she wants me to put my bike up on the stand and let her sit on it and practice going through the gears with the engine on.
