You can’t generalize against Vtwins like that, many are considered beginner bikes, especially since they make less HP per CC then I4.
Not only R6 is a horrible bike to learn on, it’s THE worst street/draily bike out there. Double stupid decision.
Older 600’s are OK to start on, but still wouldn’t recommend it.
The pink sticker bike was most likely Azn Jim.
You can start on whatever you want, but you can also sit there and bash your head against a wall.
Would I recommend either? No.
Does either get done by people who don’t give it to much though? Yes.
