There could be three probable reasons for this:
1) The Speedometer Cable is lacking in lubricant. This causes the cable inside the sheath to get stuck momentarily, get some torsional twist, then get enough torque to break free. This causes oscillations to occur where the speedometer would read in excess of a given speed and lower then a given speed. This may also only occur at certain speeds.
2) The white plastic insert in the front wheel is slipping.
3) A combination of 1 & 2.
To fix the cable, I've seen people pour antifreeze down the cable to lubricate it or replace it.
To fix the white plastic insert slipping, I've wrapped a small amount of tape on it to wedge it tighter. Do this at your own risk, as the counter argument to this is it was designed to slip easily to prevent breakage elsewhere.
