Crankcase Assembly

The Works Racing crankcases are fully interchangeable with original Norton parts (with the use of the Works drive side main bearing).

They are machined from the best quality magnesium castings on our own state of the art CNC machines.

Every possible effort has been made to optimise the accuracy of the parts during machining.

Each and every feature is produced using a specially produced jig and the latest in cutting tool technology.

The result is an assembly of great precision, giving smooth running, improved durability and race winning performance.
