As of 2015, repair manuals for Suzuki ATVs are not available online for free, however, Suzuki provides ATV service manuals for purchase on its website. RepairManual.com and Cyclepedia.com also offer Suzuki ATV manuals for purchase.
ATV owners can purchase service manuals from Suzuki by clicking on Motorcycles and ATV on the Suzuki home page and clicking on Manuals under the Accessories heading at the bottom of the ATV tab. Owners can then search for manuals by entering the product type, model year and model into the search engine.
Haynes also offers a DIY repair manual for Suzuki LT-Z400 2003 to 2009 models.
