Hey Oscar, welcome to probably the best bike in the World. Ref getting it on it’s centre stand, there are two ways; 1. Put a 1” wooden block where you know the rear wheel will be when the bike is ready to be lifted.
2. Hold the left bar with your left hand, right hand ready to pull up on the pillion grip, then use your LEFT foot (instep, not the ball of the foot) on the centre stand, preferably with a heavy soled boot. Push down with your foot while pulling up with your right hand and back with the left hand.
In short, it’s a knack!
