Barrell & Piston Assembly

The Works Racing piston and barrel are fully interchangeable (together or independently) with
original Norton parts.

The piston crown profile is as original but the undercrown and skirt utilise the very latest piston
technology.

The pin bosses are "strutted" or "cross braced" giving increased stiffness and the skirt is coated
using state of the art low friction tribolgy.

The CNC barrel is machined from solid alloy.

The bore is then Nicasil plated and honed with great precision.
