This was a Christmas present for my son. He was so excited. The lake we live at allows atvs, so we decided to get him one this year. Putting the unit together was not to bad, good thing I have been around atvs my whole life because the disk it came with did not work, but was able to get it fixed without much problem. He rides it almost everyday, even in the snow and the 125 ATV gets around pretty good. Thanks again Tuff Atv's.

Warranty is for manufacturer defective parts, not labor, if you have a part that is defective we will give you a replacement part at no charge, you are just responsible for a modest $14 shipping and handling fee. We have live technical support available to our customers free of charge by phone or email with our trained service techs for any questions or help you need. See warranty page for more details.

    Some Assembly required: The ATVs are completely assembled in the factory and fully tested. Wheels, Battery and handle bars are removed after testing. Item will be shipped in a crate, to assemble, put the above items back on. For safety precautions, be sure to check and tighten all nuts and bolts prior to use. Be sure to change your engine oil and check for appropriate engine fluid levels to ensure your vehicle is operating under the recommended conditions prior to use, any additional questions, please call our tech support.

    Remember! You are buying the smart way, factory direct, saving yourself HUNDREDS of dollars compared to a local dealer, so you are responsible for performing the setup that a dealer would normally perform - such as putting on rear view mirrors, hooking up the battery, checking tightness of all nuts and bolts, changing oil, etc. Occasionally some units may need other routine items checked/adjusted such as adjusting the carburetor idle and mixture screws, checking to ensure wires are well connected, adjusting chain slack and alignment, if needed. May we suggest that if you cannot or do not feel you can perform these tasks yourself then any small engine mechanic, (ie. lawnmower repair shop, "Joe's Small Engine Repair") should be able to help you with first time setup (normally only about $40 to $50) and for any future labor needed. Just let them know we have the parts if needed to supply them and We will gladly assist you with any technical questions.
