The TFT screen on my little KTM is about 6.5" inches across. So they must be getting pretty cheap. It is easy to select a number of functions using backlit buttons on the left handlebar. Yesterday I replaced my battery and naturally the clock time needed to be updated. That was easy to do once I read the owner's manual and discovered the secret. But the other thing I discovered was that the program also contained a date, which I hadn't messed with since I bought the bike in April of last year. The date set by the factory was March 3, 2018.
Once I reset the date correctly, a big yellow Service warning came up on the display. Since having the selling dealer perform the 600-miles servicing and getting hit with a $650 bill, I have decided to perform my own servicing from now on. So I adjusted the date back a couple of years and the Service warning vanished.
Not at all like my BMW that will bug you with a service warning until you take it into your dealer for the factory-approved servicing - unless you reset the service date with a GS-911 device.
Anyway, I mention this because TFT displays are becoming all the rage lately and having buttons (the backlit feature is really handy at night) on the left handlebar are a lot better than if some company comes up with a touch screen. While that might work in a car, it would not be safe on a motorcycle.
Personally, I think color TFT screens are a big improvement in readability compared with LCD screens. Provided that the programmers don't get carried away with complicated layers of information that must be accessed by diving into the different layers. I think most riders don't need to be overwhelmed with too much information regarding their bike shown on the display, especially while they are riding.
