I, too, can recommend a centerstand for the 919. Mine is the Honda stand with the center section of the top cross-tube cut away to the width of the exhaust collector as per WT posts. If I'm touring, I install it with the springs and use it to lube the chain easily. If I'm riding locally, I remove it. I also use it for maintenance in the garage without the spring, sort of like a center/shop stand. Versatile and easy on-off. It takes like 30 seconds to install/remove without the spring, a minute with.
I like it.
