Two cylinders should be slightly more efficient than four, in terms of thermodynamics.
Twins have a smaller surface area: volume ratio than fours of the same displacement, which reduces the thermal losses of combustion. They are also more likely to have larger valves, reducing pumping losses during operation. -Kurt On Oct 22, 2015 12:22 PM, "roscopico13 via Nighthawk Motorcycle Lovers!" < [email protected]> wrote: > Interesting point.
