Frequently Asked Questions

What's the difference between this and a traditional stone hone?

The nylon flexhone removes microscopic peaks left by stone honing without enlarging the bore — it creates a plateau finish that helps rings seat faster.

Can I use this on plated cylinders?

Yes — this brush is safe for both plated and cast iron bores.

Do I need special equipment to use a flexhone?

You'll need a drill motor or honing machine that can run at proper RPM. Always use the brush wet with honing oil and follow Wiseco's speed recommendations.

Is this for high-performance builds only?

While ideal for performance engine building, any rider doing a bottom-end rebuild can benefit from the superior plateau finish for better ring seating and compression.
