IIRC isn't this a bearing grease typically used for bicycles? There are certainly many other brands of calcium-sulfonate greases on the market, for more demanding applications.
When I want to know something about a specific chemical product, if I can't obtain the manufacturer's technical specification information, I often go to the Material Safety Data Sheet, e.g.
www.motorexusa.com/msds/171-620_US_BIKE_GREASE_2000.pdf These will often list out the most important constituents, temperature properties, etc. which can tell me a lot about the suitability of a product for my application.
Among other qualities, calcium-sulfonate greases are well known for their water resistance. They resist washout better than many lithium-complex greases, and can be better at rust inhibition. Is this called out for a KTM motorcycle application? Regardless, what are the "high bearing loads" you intend to use it for? Where some calcium-based greases can fall short, is temperature resistance. This not to state that there aren't reasonably high-temperature tolerant calcium-sulfonate grease products. It's all about the application.
Not really sure what information you're seeking ... I'm NOT going to state "calcium sulfonate greases are always better than lithium complex" - because they aren't. There are so many specialty lubricants available these days, and machinery has become complex to a point where there's no one-grease-for-everything. Without knowing more about what you intend to use it for, it would be difficult to address this further.
