Now that the H2R has set a record or two:

it's probably worth thinking about some of the the engineering behind it.
If that bike was making about 240kW (presumably at the crank), that is a lot of heat to get rid of, but not all the heat made makes the crank turn. Only about 1/3rd of the heat made creates the mechanical power we want.
If we are generous and say that 40% of the heat made creates H2R crank power, that means the H2R is shedding (240 X 1/0.4)kW, or 600kW of heat out the exhaust and radiators and off the power unit surfaces.
A typical little fan heater at home makes about 2.4kW of heat at full blast. The H2R would be making total of about 600/2.4 or 250 fan heaters worth of heat. Imagine what that would do to your electricity bill.
Assuming half of the heat is going out the exhaust pipe, that leaves the cooling systems to deal with about 125 fan heaters or 300kW worth of heat.
That is a lot of heat for a compact cooling system to deal with. Imagine the size of the radiator a 240kW car would have.
I have to wonder whether the H2R cooling systems are capable of sustaining full power indefinitely. I guess we would have to set up a dyno inside a potent wind tunnel to really test it, not that there are many places you could actually ride one at full blast for long anyway.
