I will have a look and see if I have some pics that show the engine mounts. Because it has made a difference. Biggest difference I noticed was at the end of the straight the bars no longer grow to twice their diameter.
Front mounts are basically similar to those found on rubber mount Evo\s. A rubber bush inside a tube.
Looking back on it the vibrations do make it harder to ride the bike. They tire you out. The bike is certainly still not as smooth as a Honda 4 or even an 850 Triumph. But it's an improvement that I would say is definitely worthwhile. I suspect that long term I will also see benefits in that fewer parts may brake from stress set up by the vibrations.
