Not true. Much more going on here than badge engineering. Please Google a photo of a Downtown 125. It is a much different bike than an Agility 125.....nearly 10" more wheelbase & 100+lbs..
Some countries can buy maxi sized scooters with small engines.
No expert, but doubt a 300 engine will slip right into the place of a 125. Hopefully a Downtown owner will help you with your original question regarding an engine swap.

Thanks, I Googled a photo and I have never seen a 125 Kymco like that before. I guess that model has never been imported to South Africa before.
I was not aware of the longer wheel base - always thought the manufacturer only slapped on different fairings and stickers for marketing purposes. Having said that, the manufacturer did make changes to the scooters without bothering to change the Owner's Manual. My owners manual is proof of that.
The image of the gearbox at the manual looks different from the gearbox on my scooter....so who knows, maybe some 125cc models came with different gearboxes....
Anyway, I guess most of us are still learning.
