Gray iron cylinder liners and brake drums for motorcycles and for ATVs. Casting and CNC machining are done within one group, so castability and machinability are reviewed together before tooling is made.
For motorcycles and ATV. Gray iron with controlled graphite structure for wear resistance. Bore and outer diameter machined to drawing.
For motorcycles and ATV. Gray iron with controlled braking-surface hardness, roundness and runout, and consistent wall thickness.
