The 100,000 lb. rating you mention refers to tensile strength. Tensile strength is the measure of the amount of force it takes to pull a material apart (see video below of tensile strength test). Tensile strength is unrelated to how much a given material will flex.
To quote an article discussing the use of chrome-moly in bicycle frames:
Chromoly (Chrome Molybdenum) Steel
A workhorse of the industry, chromoly is a light, strong steel. When it is butted and shaped to take off excess weight, it can deliver a fairly light frame that will last through years of hard use.
Chromoly is responsive and offers good flex while maintaining its form.
Flex is not out friend in motorcycle frames. This is why frames have so much triangulation built in - to reduce or hopefully eliminate frame flex. Once you reduce the frame to a single tube, you can expect flex. Believe it or not, even a rifle barrel flexes when a shot is fired through it, but that is not a reflection on the quality of the material being used. There’s a reason bikes with single tube frames are known as flexible flyers.
