On an Aprilia I didn't use "Liqui Moly", but a different French brand of oil that was 10W60. It wasn't cheap and is was Aprilia who recommended it as an alternative oil in North America. Over time I switched to 5W40 and didn't notice any difference performance, mechanics nor engine sounds. I did notice a change in the oil change cost.
Both oils were full synthetic.
