YAMADA develops, manufactures and offers a wide range of parts for both small and large 2-wheeled vehicles, with displacements from 50cc to 1500ccs. Our product line includes pump parts, brake panels, speedometers, and gearboxes as well as transmission parts for the belt converter systems used in smaller motorbikes.

Oil pumps

YAMADA offers an abundant variation of discharge rates for its oil pumps that are installed in motorcycle engines with displacements from 50cc to 1500ccs. These pumps must be more compact and lighter than those used in passenger cars and as a result, the walls of the pump housings are as thin and lightweight as is physically possible and small size rotors that create minimal friction are utilized that lead to extremely high efficiency in pumps that are not affected by cavitation even at high revolutions. We also offer a wide variety of other small, lightweight, low cost pumps.

Water pumps

Water pumps are responsible for circulating cooling water throughout the engine in order to maintain the most appropriate temperatures for each part of the engine. Yamada has developed a wide range of pumps with a wide range of variations designed to be used in 50 ~ 1800 cc engines. Our bladed-wheel impeller in our pumps for 50 cc engines utilizes a magnet to create a magnetic drive pump that is the first of its kind in the automobile industry.

Brake Panel

Brake panels operate by pulling on the brake cable causing the brake cam to rotate. This forces the brake shoe to expand in order to create friction between the brake drum and shoe and causes the rotation of the wheels to stop.

Speedometer Gearboxes

The speedometer gearbox is installed on the left (or right) front wheel. By measuring the rotations of the wheel, the gearbox transmits this information through the gear and pinion to the speedometer where the revolutions are shown as a ratio representing the speed of the vehicle.

Belt Converter Parts

Belt converter systems are systems that transmit torque from the engine to the rear wheels via a (deleted) belt in order to automatically engage the most appropriate gear ratio with respect to the speed of the vehicle. Aside from serving as the main force operating in the transmission of motor scooters, these systems are also widely used in passenger cars, golf carts and other vehicles. Currently, our manufacturing activities of belt converter parts are expanding in Japan, Europe and China.
