Vertex Four-stroke Pistons:

When it comes to power and performance, Vertex four-stroke pistons are hard to beat. Forged from the highest quality 2618 aluminum alloy, Vertex pistons are perfectly suited to handle the rigors and high pressures of today's modern four-stroke engines. Plus, to aid in the break-in process and reduce wear, every Vertex piston utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt.

  • Bore size: 76.77 mm.
  • Compression ratio: 13.6:1.
  • With the purchase of a premium quality piston, every Vertex piston kit contains a complete set of nitride-coated or chrome-plated piston rings, a fully case-hardened wrist pin and circlips - all at a competitive price.

Compression Ratios and Hi comp option?
Is this the correct compression ratio? The Vertex website offers a OEM replacement (13.2:1 for Honda CRF 250R 2010) and a high compression for 14.1:1. I'm not sure where the 13.6:1 comes from but it seems like a happy medium if its correct.

If you order this piston for a 2010 CRF250R you will receive a 13.2:1 compression piston.
