I own 4 bikes and have been trying different oils for the last 10 years. I have not yet found a way to accurately compare different oil brands. That stated, the two factors that seem comparable are the effect of oil on shifting and how it looks after each replacement. Using Motul 7100 has substantially improved shifting, and the during replacement, the oil looks cleaner than any used before. Adding this limited experience to the few online published tests would seem to indicate it is one of the best oils available. Until further evidence points elsewhere I will continue to use this oil.
This stuff works so well. Its so sticky that when putting it on the airfilter, as the filter expands from a squeezed ball, it makes thousands of sticky strings. That is what I want holding up all the dust particles that try to make it through the airfilter. This stuff has never let me down. Its tough to clean airfilters though, but that is a good thing! If any oil is not removed during the cleaning, well its so sticky it will keep doing its job the second time around too.
