Running in almost done so now I can report that the little SYM is going very well. The engine is willing to rev up to 9000 rpm and close to the red line. This gives it an indicated top speed of more than 70 mph with a following wind but I haven't kept it on full throttle for too long yet. Realistically it will cruise at a genuine 60 except on long hills where it sticks at about 50. I have done the first oil change and the old oil came out very clean. Mesh filters had no debris whatsoever.

Brakes are some of the best I have experienced without making any changes to pads. ABS is reassuring and unusual on a 125. The fuel tank is very big and with consumption being around 100 mpg the range is well over 200 miles.

Minor complaints are that all distance recording is in Km and can't be changed. Running boards are a bit high and cramp knee joints a little even though I am of only average height. The big fuel tank takes ages to fill because of restriction in the filler neck. There is a strange characteristic in the throttle response from rest which makes it hard to take off really quickly for the first second or two. This could be a deliberate safety feature or maybe just something which improves tyre life but there is no actual traction control.

It's great that the engine is performing well, reaching those 70 mph speeds with a tailwind. The fuel economy is impressive too, giving you a solid range. Glad to hear the oil came out clean and the brakes are top-notch, especially with ABS on a 125.

The small annoyances you mentioned, like the KM readings and the high running boards, are understandable, but they don't seem like dealbreakers. And yeah, that throttle hesitation at first could be a safety feature—probably better for smoother riding and less stress on the tires.
