I had to go back in time a few years to find a NDS picture. This was how the Competition looked pre-gugificazione.
I have a theory about this.
When I first started riding bicycles, they had kickstands. Kickstands were always on the NDS. Who is going to put the kickstand up, then walk around to the other side of the bike to get on it? Once the habit is formed, it tends to remain.
