rollers need to be experimented with try fitting different 1s and see if it makes a difference my mate went through 7 sets before he was happy with the result my piaggio NRG tops out at 58 but because the rollers are either the wrong weight or need to be replaced it accelerates poorly. try adrenaline pedstop they have malossi rollers that shud fit ur ped and the postage and packaging isnt too expensive
good luck
