    • Customer Review

      Excellent Service, Excellent Manual

      Great service, manual arrived quickly through Aus. Post. Very extensive. Can do basic service and a bit more with My limited experience. Suits the professionals too, I assume!

    • Customer Review

      Digital version a great bonus

      Being able to have access to a manual on my phone or laptop is extremely handy, so being able to get that as well as the hard copy for the same price is great. It turns out my bike came with an official manual, but this still has useful stuff for on the spot repairs.

    • Customer Review

      Happy Customer

      Having recently purchased a quad bike and wanting to know how to repair and maintain it, I was pleasantly surprised to find a company that provided a manual and online version for the exact make , model and series. Couldn’t have asked for anything better.
