Does the motorcycle front brake need refueling? What kind of oil do you want?

Motorcycle disc brake needs oil, which is special brake oil. Brake oil is pumped into the brake pump from the upper brake on the handlebar, and the lower brake pump is controlled by the oil pipe to push the brake friction plate to brake completely. In general, there is no shortage of brake oil. As long as there is no shortage of oil through the oil window on the pump on the brake, it is generally not necessary to replace or add it.

Motorcycle consists of five parts: engine, transmission system, running system, steering, braking system and electrical equipment. The overall structure of motorcycle and the names of its components.

lubrication system

The four-stroke engine adopts splash lubrication and pressure lubrication. Two-stroke engines generally adopt a mixed lubrication method in which a certain proportion of QB gasoline engine oil is mixed into gasoline. However, no matter how the engine works, this kind of lubricating oil is supplied according to the set proportion, which increases the consumption of lubricating oil, and incomplete combustion leads to more carbon deposition and great exhaust pollution.

The new generation of two-stroke engines all adopt separate lubrication mode, and are equipped with separate lubricating oil tank and oil pump. The oil pump generally adopts reciprocating plunger variable oil supply pump, which is driven by crankshaft gear through worm gear. The oil supply is connected with the carburetor throttle through the throttle handle and control cable, so that the oil supply changes with the engine speed.
