Hi, everything I write here is translated by google translator. I do not know English in my mouth. I also own the BMW G310R. I observe the temperature of the coolant. After the first start, outdoor temperature around 20C - 68F. By driving at a low load of 80Km / h, the temperature on the road reaches 60-65C, that is 140-150F up to 5Km. If I drive with a max load it is heated to 80C it is 176F. Then, with lower load, it cools down to 65-70C 150F. It sounds like a faulty thermostat. Your BMW g310R behaves the same way. The seller told me it was normal. Thank you for your answers.
