2-Wheeled Vehicle Parts

Cam Sprocket

The sprockets that drive camshafts are typically made using a combination of fine blanking and cutting processes. However, we have slashed costs by mass-producing these products using only a traditional press.

Tappet Shim

This part is to allows tappet clearance to be adjusted. Using our proprietary methods, we are able to produce 94 types of 0.025mm thick products, grinding both surfaces to within a tolerance of ±3µm and then using a YAG laser to mark them according to type.

Pulsar Rotor

We make these parts that are used to regulate spark timing for all sizes of two-wheeled vehicles.

Clutch lifter

These parts are used for engaging the clutch in small motorbikes. They are usually clipped with a pin produced on a lathe, but we have been successful in making them as a single pressed whole.

Knock Pin

These pins are used to position the cylinders and the crankcase. They are normally made by cutting a pipe and forming it on a centerless lathe. However, we have used our knowledge of press techniques to produce them with presses in a single step process.

Oil Strainer

These are oil strainers used in motorbikes.

Valve Spring Sheet

We cooperated with a motorcycle manufacturer to develop a pressing process that reduced the production cost of this part that is usually made by a cutting process.

Rocker Arm

We developed a press process in cooperation with a motorcycle manufacturer with the aim of reducing costs for this part that is usually manufactured by forging.

Shift Drum Stopper Plate

Through application of our metal-working technology, we have been able to mass produce these motorbike gearshift parts, which demand the highest level of sectional quality, using traditional pressing methods.

Brake indicator

This part measures and indicates the level of wear in the brake-lining.

Thrust Washer

This part, used in the engine and transmission, requires an extremely high level of flatness and parallelism.
