@An Orange Crush,
to compare an AK 550 with your DT 300 or a XC 500/i takes a little bit of consideration.
The AK 550 is a complete different motorcycle, be it motor, transmission, suspension or seat comfort, not bad at all but as said different from ...
A DT 300 or a XC 500 were concepted as "scooters" in layback sense of this word.
One cylinder, CVT with rollers and belt in one casing, suspension conventionell.
Kymco produces modern and state of the art motorcycles, which all, treated properly are very reliable.
The only way to find out whether this model AK 550 suits you, is to do a test ride. MJ ..23 or ..24 ist just a question of taste and money.
