Are you in Pattaya? there are pot holes, bumps, drains everywhere, i tried new rear YSS shocks on my Click 160 and it did FA, best solution is avoid short cuts and try to avoid bumps going slower, the other game changer for me was lower back stretches 2+ times a day, that really helped. I reckon all scooters are similar, i looked at a new Forza the other day, still big bump over speed humps
