After 2000km, the bike is still good. I consistently riding it at 100-110km/h to my office and back. So far, everything is okey.
The ride is always very comfortable because the suspension is very soft. But during windy situation, you will get a bit of a wobble if a crosswind hit you. But no major problem actually.
But, my front fork (left) is leaking fork oil. I will have to send it for service soon. I wonder if parts will be available.
I will update after completing the exercise.
