So I recently spent 24 hours with a rental Diavel in TX hill country. Rode on a cold day to get used to it, then took a long ride 2 up, then a shorter ride 2 up on the third day (rental period started at 2pm).
Impressions:
The key fob sucks.
Wow, this thing is spooky in turns.
But fast!
The key fob sucks.
Pillion in a million noticed her knees weren't hurting after 4 or so hours... bonus! Neither are mine! She can see where we are going due to the seat, but all the rest of the passenger ergos are wrong: grab bar sucks, tank is too far away, seat is slippy.
This thing gets terrible mileage, and the tank is way too small.
The key fob is stupid!

Oh, that's how you switch modes... I like Sport better than Touring. I hate ride by wire throttle.
Oh, look, a red light... maybe I should see what Urban is like... Why the make the beast with two backs would I want the same bike with LESS horsepower??!! Turning this thing back to Sport at the next stop light.

In the end, I really don't want one. The key fob is the most annoying experience I can imagine living with. The bike doesn't recognize your arrival until you have dicked around holding it in various places and flicking the kill switch, pushing the starter button, pushing any button you can find, etc. for an indeterminate amount of time/dicking around.
Unless you left it in the seat lock (pointed down, under the tail, used to access the surprisingly useful tool kit - allen keys and everything) where it is likely to fall out and leave you stranded when you run out of gas 90 miles from when you filled up last. Once you get it running and start to ride off, it may forget where you put the key fob and warn you the key is back where you started... but it is really still in your pocket.
And you still have to dig this thing the size of a flip phone out of your pocket every 90 miles to put fuel in it!
The rental place was great, however. Accomodating, useful, not unreasonably priced, lots of options, and friendly. On their website, they talk about a fee for drop off on the days they are closed, but there was no talk of such nonsense when I scheduled the drop off on a closed day. If you are doing something in or near Austin and want to get your ride on, Lone Star Motorcycle Rentals was good to me.
