First silly question: The red button the the right side hand grip (same position as the horn button on the left side) - what is it for? I can't seem to find any function that this button performs. Is it just a "dummy" that's not used in this particular model? (Hey! How about we use that switch to control regenerative braking on-demand?)
Next silly question: The rear brake rotor has already warped and is creating a very annoying "chirp chirp chirp" as it moves the caliper back and forth on it's alignment pin. The rotor is way too thin to even think about machining it like you can turn a automotive brake rotor. I would have thought that since the factory rotor was drilled that it would have disipated heat fast enough to prevent warping - but obviously not the case here. Personally I feel that a thicker rotor would be more appropriate, since the extra metal mass can absorb (and release) the heat of braking without distortion. I have never played with cycles before, so I really have no clue how to go about looking for different size rotors/calipers/brackets that would be appropriate for this machine. Can anyone help with guidance on a possible solution to this?
How about others helping to chime in on this topic with quirks/fixes for their XM3K?
