The OS SPEED 19XZ-B motor with a capacity of 3.1 ccm is the perfect competition motor for the offroad M 1:8 class. With the smaller motor capacity, it saves around 10% fuel compared to the OS SPEED 21XZ-B, whilst providing more than adequate power. This is the key competitive advantage in the battle for tenths of seconds. Depending on the course duration, 1 or 2 refuelling stops can be saved. The OS Speed 19XZ-B makes savings in terms of consumption, but there is no compromise on equipment. The ceramic bearings used and the specially coated crankshaft ensure reliable running characteristics and longevity in conjunction with maximum efficiency.
