What advantage in a parallel twin-cylinder motor does a 180 degree crank have over a 360 degree one?In: Motorcycles |
[Edit] |
Answer
A 180 degree setup will allow for two power pulses per revolution, and thus a smoother power delivery. Additionally, there would be lower side loading on the crank due to the counterbalancing effect of one cylinder travelling the opposite direction from the other at all times.
A 360 setup will give a larger power pulse half as often, similarly to a large-displacement single cylinder engine (commonly referred to as a "thumper"). This can be advantageous in soft ground for avoiding wheelspin.
