Some good points. TBH I just find the Japanese 125s a bit boring to look at and my original interest was piqued by more retro stuff.
Benefits of new Chinese is that I know nothing and dont want to tinker, so new, and warranty is ideal. Getting a Honda say is more money and used.
But you are right, one of three things will happen:
1. I dont like it so want to sell, Chinese = harder sell and depreciation. A Honda may get me 90% of spend back
2. I do like it, too much and want to move up to a 350/400/600 bike, so similar scenario to 1
3. Its fun but happy with it and no desire to upgrade, would probably be happy with Chinese as wont be riding too much, garaged and dont plan to ride in rain!
