ATV and quad parts
Last updated
A large share of the quads sold in Western markets are Chinese-built around a handful of engines — the same GY6 and horizontal-single families used in scooters and pit bikes. Once you identify the engine, the engine parts problem is solved.
The chassis is another matter: frames, axles, hubs and bodywork are model-specific and frequently unmarked, and that is where quad orders go wrong.
In this guide
Engine parts: mostly solved
- GY6-based 150cc and 250cc quads share transmission and engine internals with scooters of the same family.
- Horizontal-single 110cc and 125cc quads share almost everything with pit bikes.
- Ignition, carburettors, filters and gaskets follow the engine code, not the quad's brand.
Chassis parts: measure everything
- Axles — length and spline count vary and are rarely listed.
- Hubs and wheels — bolt pattern and centre bore.
- CV boots and joints — by dimension.
- Brake components — disc diameter, pad dimensions, caliper mount spacing.
- Bodywork — model-specific, bulky, and the worst thing to get wrong.
Identifying an unbadged machine
Find the engine code on the crankcase first; that settles the engine. For the chassis, photograph the frame number plate and the part you are replacing with a ruler in shot, and measure the mounting points.
The brand on the plastics is frequently an importer's name applied to a chassis built by someone else, and searching it produces nothing useful. Dimensions always work.
Shipping notes specific to quads
Bodywork and frames are bulky and bill on volume; wheels are awkward; complete axles are long enough to need oversize handling. Consolidating a quad parts order with denser items averages the freight out considerably.
Questions & answers
Common questions
- My quad has no brand. Can you still find parts?
- Usually. The engine code plus measurements of the part you are replacing is enough for most components.
- Are Chinese quad parts interchangeable between brands?
- Engine parts frequently are, because the engines are shared. Chassis parts are not, and assuming they are is the common mistake.
- Can I get a complete engine?
- Yes, by sea, drained and declared. Air freight on a complete engine is rarely economic.
