I measured the vibration (jerk) on the left and right side of different motorcycles. I tested different engine types: Boxer engine, 3 cylinder, and V4. I measured the vibration on the same route, while driving for approx 30 minutes. I take the average jerk for every measurement. For every measurement the jerk on the right side of the motorcycle is higher than on the left side. I switched my sensors, since I thought this would be due to my sensors, but the results are the same. The difference is about 5-10%.
I'd thought that the vibration would be more or less symmetrical, but it seems to be different.
Could you think of a reason why the vibration differs?
Due to comments and answers here is some additional information:
- I ran the experiment with different participants on different motorcycles
- It seems that the difference of jerk occurred while standing, as well as driving (I cannot measure new data right now - but evaluated my existing datasets)
- This is the route I used
- The motorcycles used in this experiment are regular ones you can buy at any retailer
