I am a car blind, intends to buy a motorcycle, give some advice!
Body parts with materials: A plastic parts: body plastic parts are generally ABS, PP and other materials. PP cheap, compared with ABS: shrinkage, hot and humid weather, resulting in deformation of plastic parts, low strength, poor toughness, paint adhesion is poor. ABS can be divided into imported and domestic materials, imported ABS plastic parts are not permanent deformation, impact resistance, paint adhesion strong, do not paint off.
Start mode: start the way to start the foot and electric start, and now a lot of cars are equipped with electric start and foot start, but the focus is different, and some car drive is not off, plus the electric start is only furnishings, electricity Start is reliable depends on the quality of the battery and the motor, a good import motor and the general price of nearly a thousand dollars difference.
Carburetor: carburetor with plunger and vacuum diaphragm type, now high-end four-stroke mostly vacuum die. Vacuum diaphragm carburetor can automatically adjust the intake air volume according to the change of the engine speed, so the fuel consumption is low, the slewing speed is smooth and the ride is comfortable. The latest technology of the vacuum diaphragm carburetor at the same time with multi-functional structure. Such as accelerating pump, inertia enrichment system, idle system, start enrichment system, heater and so on.
Igniter: There are many types of ignition, the price difference is also larger, four-stroke engine with the exchange of analog circuit CDI and DC circuit CDI, now the advanced ignition is a DC digital all-transistor ignition PEI. A good igniter can provide the exact ignition advance angle required by the engine to prevent the impact of the engine crankshaft crankshaft, increase power, reduce fuel consumption, reduce vibration, ride comfort.
. engine: the engine is the core of the motorcycle, the engine life to determine the life of the motorcycle, the engine's performance determines the performance of the motorcycle, the engine power, vibration is small, then the motorcycle ran fast, riding comfort. The same type of motorcycle price difference is the largest component of the engine, buy a motorcycle, do not just look at the style, depends on whether the engine is the same.
