Cylinder Works

Does your motocross bike, enduro bike or ATV need a new cylinder at the next engine rebuild? Cylinder Works makes replacement cylinders and cylinder kits for off-road motorcycles and ATVs, so you can rebuild the engine without hunting for OEM parts. Here you'll find standard bore cylinders, big bore kits and complete kits with piston and gaskets.

Cylinder specialists for off-road

Cylinder Works specialises in one part of the engine: the cylinder. The brand is aimed at riders and mechanics in motocross, enduro and ATV, where engines are ridden hard and need regular rebuilds. Instead of reboring and replating a worn cylinder, you can fit a new one that's ready to go. The focus is on precise fit for each model and a durable cylinder wall coating, so the engine keeps its seal and performance over many hours of riding.

Cylinder Works' key products

Standard bore cylinders have the same bore as the original and are the obvious choice when a cylinder is worn or damaged. Big bore kits increase displacement for more torque and pulling power, typically together with a matched piston. Cylinder Works also offers complete kits where cylinder, piston, rings and gaskets belong together, so you have everything for a top-end rebuild. See each product for model and year fitment.

Frequently asked questions

When does it make sense to replace the cylinder instead of refurbishing it?

When the cylinder is scored, the plating is worn, or you want to avoid waiting for a rebore and replating. A new cylinder is ready to fit and makes the rebuild more predictable.

Does a big bore kit require other parts?

It depends on the model. A big bore kit may require adjustment of fuel injection or carburettor, and sometimes different gaskets. Check the description on each product and contact us if you're unsure.
