Well, it'll be the biggest baddest when someone gets it installed. I remember seeing an Australian bike which used a couple cylinders from a Rolls Royce V12 fighter plane engine, and it was quite a sight to see it installed.
Guess I'll have to read more. My first thought is that with that kind of torque, it probably has no gear box, so to slow down the ship or back up, it will take some auxiliary support - or maybe stop the engine, switch the injector timing, and restart.
At least with those steps down into the crank case, it would be easy to get at the crank for service. Provided they remember to drain out the oil first, anyhow. No need to pull the engine out of the ship to work on it.
