And this goes back to the handling thing, not everyone is good at managing a super racy bike. Turning tends to be "easy" which might also be "twitchy" if you are a newer cyclist. It usually takes more concentration to keep it straight, and you might lose a bit looking behind you! Especially if you are new to that riding style.
