Bought a 2 year old Quadzilla 300 Auto for light agricultural work. Big mistake ............. Paid £1,500 for it then spent more than £1,000 to keep it going. Never had a Quad before so I thought a cheap Quad would be ideal to try it before spending £10K on a Honda. List of the more major problems as folloews. Gear change was useless, based on the idle speed of the engine the "clutch" engages but it proved impossible to set the idle speed so the gear change worked smoothly and the bike didnt stall because idle was too low. Cluch broke twice in 6 months, got one for free under warranty .... but not the point is it? Bolt fell out of rear suspension, suspension collapsed, crashed bike and trailer - Chinese don't use locktite or locking nuts it seems. Control panel self destructed. Main brake pedal sheared off - another crash. Rubbers and tubes perished and rotting like it was ten years old and had been kept on the beach not in a clean, warm shed, same goes for anything steel it rusted as I watched, not seen that since they made Austin Alegros out of recycled coke cans in the 70s. Bodywork rattly and missing half its bolts after a few days work. Exhaust sheared a bolt - cheap steel in a cheap head. Engine sounded like a cement mixer full of shrapnel. Good points - it did go through mud well and had some decent power but at the cost of bits falling off and breaking with regular monotony. However it has proved such an indispensible bit of kit I have happily scrapped the thing and bought a new Honda. If you are thinking of buying even a brand new Quadzilla think again, it is a waste of time and money. Terrible build quality and very inferior materials.
