Seat
0

Thicker or thinner seat. Lower makes it easier to reach the ground.

0

Lowers the whole bike. Easier to reach the ground, a little less legroom.

Handlebar
0

Raises the bars. You sit more upright with less weight on your wrists.

0

Brings the bars closer to you. Shorter reach, good for shorter arms.

Footpegs
0

Lowers the footpegs. More knee room, less cramped legs.

0

Moves the pegs back (or forward). Further back feels sportier.

Windscreen
0

Taller or shorter screen. Changes how much wind hits your chest and helmet.
