I have never experienced the hill start, so no comment on its practicality, but I read somewhere in this forum that it’s only a software program as the bike comes with all the necessary hardware, so why not having it if it’s there for free!? Even if it’s just a marketing wow.
After all not everybody who buys the RR is buying it for tracking purposes, so the hill start would make more sense to them (including myself).
And I agree, if someone can’t manage a hill start on a liter bike (honestly it’s easier on these bikes than smaller ones due to their power) then they have no business sitting on a liter bike, for the rest, enjoy the cool option as it’s built to make our life one step easier.
Sometimes I miss the kick starter of my first bike! ... only sometimes.
