Hi, I tried to get my F650 serviced in Darwin,the company is only setting up and is a Hyundi Car Dealership, not very helpful and blame everything on transportation costs and delays from Melbourne. I needed a 20000k service before venturing to Singapore. Run out of time and arranged the service at Performance Motorcycles Singapore! Best of Luck.
