What is included in the Cylinder Works Big Bore Cylinder Kit?

The kit includes the big bore cylinder, a hand-matched Vertex piston, and a complete top-end gasket kit with o-rings. This provides the essential components for the cylinder upgrade.

What material is the cylinder made from and why is it important?

The cylinder is made from a high-quality 2618 aluminum alloy. This material is chosen for its superior strength and durability, which is important for handling the increased performance and heat generated by a big bore engine.

How does this kit improve my Honda CRF 250 R's performance?

By increasing the engine's bore size to 81mm, this kit effectively raises the engine's displacement. This generally results in increased horsepower and a more potent power delivery, making your bike feel stronger.

About this part

Product Details

This is the Cylinder Works 81mm Big Bore Cylinder Kit, designed for the 2004-2009 Honda CRF 250 R. It's built to give your bike's engine a noticeable bump in power and displacement, making it feel more potent on the trail or track. The kit aims to provide a performance upgrade that looks similar to the original cylinder but performs significantly better.

Inside this kit, you'll find a Vertex piston that's been carefully matched to the cylinder for a precise fit. This attention to detail helps ensure smooth operation and reliable performance. The cylinder itself is constructed from a strong 2618 aluminum alloy, chosen for its ability to handle the increased demands of a bigger displacement engine while remaining durable. By increasing the engine's displacement to 81mm, you can expect improved horsepower and a more responsive feel from your CRF 250 R.

This all-in-one kit includes the cylinder, a matched piston, and a top-end gasket set with o-rings. Purchasing these components together can offer cost savings compared to buying each piece separately from the OEM. It's a well-built option for riders looking to get more performance out of their Honda CRF 250 R.
