No spelling error. Since the engine is a large volume two-cylinder engine, the torque delivery over two revolutions of the crank is very uneven. Therefore, S&S say that there are torque spikes of up to 1,800 Nm. It is not the average torque, but just in spikes. This, however, makes major headache when the engine is coupled to a conventional gearbox. Apparently and elastic coupling which absorbs the spikes has to be used. in the tree-wheelers I saw and heard at Goodwood, you could literally hear this coupling squeak at low revs.
I wonder how reliable that is in long-term use ...
