Quad bike pistons and rings

Match the engine and size details

Check whether the listing is for a two-stroke or four-stroke engine, where stated. Compare its bore, piston size and standard or oversize details with the information for your engine. A similar bore figure or model-family name alone does not confirm fitment.

Check the kit contents

The range includes kits as well as rings, pins and circlips. A piston kit, ring set and individual component are different listings; check the unit and contents to see what is supplied.

If compression or other engine specifications are shown, compare them with the requirements for your build rather than using one figure alone. Browse gaskets and seals for related engine components, checking each item against its own application.

Can I choose a piston using model and year alone?

Use those details to find the application, then confirm the size required for the cylinder. Where size grades or oversizes are offered, have the cylinder's condition and measurements checked by your engine builder before ordering. Engine capacity or the marking on an old piston alone does not confirm the next size to buy.

How do I choose replacement piston rings?

Match the rings to the exact piston specification and size, using the piston or ring manufacturer's application information. A matching vehicle name or bore figure alone does not confirm the correct ring set. Browse piston rings once those details are established.

Does a piston kit include the pin and circlips?

Read the stated contents for the exact reference; do not infer them from the word “kit”. Use piston kits to compare kit listings or wrist pins and circlips for separate components, checking their own application and quantity.

Where should I look if the cylinder is also being replaced?

Browse cylinders and parts and check what is included with the chosen cylinder or kit. Agree the cylinder and piston specifications together before ordering so that a model match does not stand in for the required measurements.
