GPX does not currently offer owner’s manuals for their line of motorcycles. We are working to create resources to ensure you know how to maintain and service your GPX! Feel free to give us a call at (406)284-9985 if you have any questions about your machine. Below are some general specifications for each of their full size bikes.

Note that some maintenance parts such as air filters, oil filters and fuel filters can be found in the parts section of the GPX moto website.
