2t engines are more fun (for me) I have a 2005 Kymco ZX50 that is modified for LSR racing. To date the best run was 87MPH.

So yeah... They have more HP/torque out of the box BUT the same CVT mods will apply.
These bikes are made/built for general purpose commuting, and were designed in countries where people weigh much less than us fat, lazy Americans.

Bottom line?
2T bikes are better suited for the US market but the CVT needs the same mods I listed for the 4T machine.
2Ts are also MUCH more finicky, and require much more maintenance. Buy only the best 2T oil, frequent spark plug changes, fuel, and air filters are bought by the dozen, and fresh fuel is a must. If the bike sits for three months... change the fuel.

4Ts require much less maintenance. Oil changes, and valve adjustments are about it.
Fuel, and air filters are about half as critical, and a spark plug may well out last any/all of us.

If you like to tinker w/ your engines a 2T is great fun. If you can't be bothered... 4Ts are better.
