Disappointment with new CF MOTO 450

In November 2024 Ii ordered a CF MOTO 450 from Droomers and it only arrived after I had left for two months in NZ. During this time bikes were delivered and feedback local and on websites was that at low speed the ride was jerky. From overseas ride reports it appeared all it required was an update/reconfiguration of the ECU so I (foolishly) assumed that my bike would have been updated before I collected it. I collected it yesterday (27/01/2025) and riding home (a distance of 45km) I realized that when traveling in traffic at 30-40km/hr the bike was surging a lot. It seems that between 3000-4000 rpm with a constant throttle the engine is not sure if it should be running or dropping to idle. I contacted the dealer and they have now agreed to come and fetch it today to see if they can sort it out. I WILL UPDATE THIS RATING IF THEY DO ACTUALLY DO AS THEY HAVE PROMISED. My point is that after selling the first batch of the imports where similar problems were reported at small throttle openings, and hopefully checking what overseas reports are saying, is that they would have been doing a thorough check on all the 450s before they went out.
