Mine will do 65 most days but will probably reach 75 in the right conditions. but I use it for comuting every day and try to keep below 55. You have to remeber they are only 125cc bikes and it don´t take long to wear out the piston and rings. However if you buy £100 quids worth of good tools includeing socket set torque wrench, allen keys (propper ones) there is no reason why you can´t keep the bike going forever. Just do your weekly checks and you will have something to relie on.
