Yeah, chain is a minor hassle that we put up with. I've actually gotta do mine today; it'll take me no more than 10 minutes but I do miss not having to do it at all. On the other hand, my chain never snaps, and it takes a lot longer to swap a broken Zero belt than it does to me to oil my chain every year.
Again correct on the motor. The large oil reservoir/sump shown in Sam's video is gone. Most of the coolant has been switched to the reservoir that was, previously, just for the inverter. The new EMCE motor and inverter now share the same water/glycol coolant mix that is easy to flush and is recommended every 26,000 miles. There is a small reservoir of the ATF like Sam had to do that lubricates the gear reduction. There's a lot less to it now, less fluid, and it's recommended every 18,000 miles.
While the deep blue original SS9 color is my favorite, I'm really liking the new color options they recently offered. Good luck on your decision!
