As there is a lot of excitement about acceleration. Here are the Zero 2013 numbers...
S: 5.3 seg
XU: 5.5 seg
FX: 3.9 seg
MX: 4.3 seg
I have ridden the FX, & S models and I can tell you they are real. You basically gain + 100% vs 2012 models. The FX as I pointed out in a different thread is a rocket...
And yes, I would like to know more about the 2012 controller modification/upgrade for improving acceleration. Does anyone know if this could be done just sending the controller?
