rollers (all illegal, likely to void your warranty & shorten the life of the scooter)
upgrade & buy a bigger scooter.
I rode & loved riding my Today 50 in baby blue for the 6 months I had it but the bike just doesn't feel like it has much more to give. Best to invest your money more wisely & upgrade to a bigger capacity scooter. The young guy who told me about the variator in particular mentioned that he managed 70kmph from his Today with the variator however the speedo on the scooter definitely isn't the most accurate so he was probably managing 60?
