RE: Troubling observations about brushless . . .
My brushless pede is very keen to flip. Due to cogging problems, I did not get a chance to really evaluate the suspension, but the speed is just absurd, even geared 16/86!
I have spacers with the stock white springs: thickest in rear, second thickest in front. Wheelies are not the problem I thought they were going to be with brushless, but the previous owner may have had the slipper clutch a bit too loose. I actually wish I had a bit more torque down low. With the stock motor and IB4200 cells, I get massive understeer with the hammer down, and it flips with a quick lift of the throttle in a fast corner, even when I try to counter steer.
