pulzelli Posted October 3, 2009 Share Posted October 3, 2009 hi ratboy , the problem with low power machiens like these is to be realistic as to their performance , wind resistance is your biggest problem , a low profile riding position will help , but on the flat with the engine not to stressed 60 MPH should keep you up with the cars , 70 MPH is down hill only , thats if the engine holds together !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
