keep in mind, bikes are lightweight and not really designed for consistant speeds over 25 MPH.. 35 MPH is really pushing your luck..

anyway. a 2 stroke will have more HP per CC, it's just there nature, but they have less torque and they have a smaller powerband than a 4 stroke.... a 2 stroke would greatly benefit from a SBP shift kit to keep it in the power band, but you would need a multi speed bike and an alloy hub
