hi my own rs125 has went to 100mph and I am fairly heavy someone light would probably take it to about 105 maybe 110 but theres noway they would go to 125 unless it had a full race engine fitted. If yours is doing 95 it must be unrestricted uk bikes are restricted but are easy to change to full power. My bike is 2001 but has a very low mileage about 4000 miles.
