I know this has been asked before but what is the difference in speed from a ZX200 to a ZX225 to ZX250. Really thinking of switching back to a Skeeter. I use to have a 2008 20I(really liked it) then went to a Triton and now in a Ranger. Just wondering what the speed difference is and at this point in my life cant justify the price difference in the FX model. Thanks Guys in advance on any input.
