Well, my ST4S has remotely adjustable Ohlins already so i did not add that. Alloy swing arm sounds nice, with a better method of adjusting the chain. Scott Oiler? Can't there be something better than that.
RED, YELLOW, SILVER and DARK GREY
Finally, just to make it more fun, an adjustable heads up display like in the Corvette (which also includes a G-meter!) that can be programmed to one's own driving preferences. More carbon and alloy parts to reduce weight, especially in the wheels.
