I bought my 900lt last year and put on 6000km. I also replaced the ECU to fix the stalling problem. I love the handling and smoothness of the bike. I also had the same experience that the bike lack power on take off. I had to increase throttle to smooth out the transition. I don´t know what´s the expected top speed but it appears the power flatten at around 140km/hr. I had not discuss this with my dealer yet but I will soon. Does any one else had the same experiences?
