Cylinder Works Big Bore Kits

Cylinder Works builds big bore cylinder kits for dirt bikes, ATVs and UTVs, using advanced nikasil plating to deliver higher compression, more displacement and added horsepower. Kits bundle the cylinder and matching components so riders can fit everything directly, and many are designed as bolt-on upgrades that drop into stock engine cases without drilling or machining.

Engineered for off-road riders who want more power without changing the bike's stock look, Cylinder Works sets a standard for increasing displacement reliably. Backed by a family of established racing brands, the company is chosen by riders looking for proven, precision-made top-end performance.

Frequently asked questions

Does a big bore kit need engine machining? Many Cylinder Works kits are bolt-on and drop into stock cases with no drilling or machining. Check the listing for your engine, or send us the model and we will confirm.

How much power does a big bore kit add on a dirt bike? It depends on the displacement jump and the rest of your setup, but the extra cubic centimetres show up first as low-end torque, which is what most trail and off-road riders feel.
