Update: the 40 days were just a guess by the dealer - as stated earlier "They have no clue..."
Called them in between for updated delivery time, last call was yesterday same answer: "Delivery will be befor the 40 days, but when we dont know"

Today a very excited Mr Li called, the bike arrived. A pity I left already, so it need to spend few more days in the warehouse.

Summary:
1. the delivery time for the XY250GY-2 is 2 weeks only,
2. the stated 40 days - 6 weeks delivery time is just a safety caution of the dealer because see 3.
3. the dealers have no access to a track & trace system, dont bother them, they are as clueless as you

I will be back in May...update then
