hey you fools....it´s just because your bikes are derestricted....Restricted bikes can do 120 km/h ...derestricted...near 180 km/h.....it depends on the derestrictions you´ve made(or the previous owner)...there are over 3 different derestrictions...but I don´t recommend them...If you want more speed just buy another bike....this bike handles well till 120 km/h...it´s too light
