Driveshaft disappointment

Strange question. What's in the bigger cylinder portion, and why is the Beemershop's shorter than the BMW shaft. However, the BMW shaft is not servicable, while the Beemershop's is, so perhaps is more overkill since there's no servicing. Also, what are those six cylindrical--hard rubber I think--for?

The black rubber cylindrical items are replacements for the dampener. Description from the Beemer Shop website:
R1200/1250 Ei Rebuildable Driveshaft for Liquid Cooled R12 Models Replaces BMW part number 33 73 8 531 102.
Uses grease fitting equipped extra heavy duty German made U-joints with removable circlips for easy replacement. Damper material replaceable by removal of one circlip. Extra set of dampers included. Fully rebuildable, all parts are available separately. Supported by a one year warranty.
U-joints are factory lubed and sealed, but for longest life u-joints can be greased every 30-40k miles. Use NLGI Grade 2 spec with an EP additive, commonly referred to as EP2 grease. One example is Chevron Ultra Duty EP2 grease but any lube meeting these specs is acceptable.

Different crank shaft orientation for one. Harder to use a shaft drive with a horizontal crank compared to longitudinal crank.
