Modifications

Try common parts and see how they change your fit. The picture shows your setup over the stock bike.

Seat

Seat height0

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

Lowering kit0

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

Handlebar

Bar risers0

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

Bar pullback0

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

Footpegs

Lower pegs0

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

Move pegs back0

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

Windscreen

Windscreen height0

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