there is no difference from a street bike and a sports bike....a sports bike is a street bike ur just using a different word 4 it......and the difference in a cruiser is its looks... speed... the way it handles.... you normally sit far back in a cruiser bike and the handles on the bike are higher and a cruiser with the some cc as a sports bike will win a sports bike in a race up until 70km then a sports will take over....hope that helps u bro..
