Wile there at it, the should get rid of bikes with single rear shocks, push button starters, water cooled engines and maybe even Camelbacks! Or maybe to make it easier, limit it to bikes built before 1967!
I drive a single seater and have no room for 8 pages of the roadbook taped to my dash or the time to buy, install or learn how to use a roll chart.
If the bike guys want to use roll charts only, they should. I don't think there's a car racer that would see any benefit.
