Anyone can ride a motorcycle, but when it comes to car maintenance and accessories choice, many senior moyo seems to be small white. Motorcycle parts many, the scope of knowledge is very wide, in the motorcycle parts competition market, it is hard to avoid some dark businessmen, sell some inferior products, some important parts and protective parts, when buying distinguish good and bad and important, good zero protective parts can ensure your safety, poor zero protective parts to your life in minutes! How to measure the severity of these hazards depends on how important you think your life is.

Many moyo do not have too much concept of "refurbished tire", think from already won't so unlucky!! But what about the bad luck? If it is said that which motorcycle accessories will be related to the safety of moyo life, it is estimated that there is no accessories more important than motorcycle tires.


However, or a lot of profiteers in order to pursue profits regardless of the safety of the life of friends, unexpectedly sales of refurbished tires, each small partner in the purchase of motorcycle tires to a bit longer heart, brightening eyes to see clearly. There is a foreign moyo encountered such a bad luck, young man riding a tire just changed not long motorcycle on the road, drive not long, the tire peeling instantly led to the motorcycle slippery tire fell car, back skin scratches bleeding.


Back skinned man, start to climb from the ground up to check the motorcycle where there is a problem, the result see peeling tires, so serious guy is fire emit three zhangs, soon because you just change a tire, guy touched back, also found that the dye in blood, by this time the most angry is that these unscrupulous businessmen, if the speed quick consequence is unimaginable.


From the picture, we can clearly see that the tire with a layer of surface skin is an old tire with blurred lines. It is estimated that the motorcycle repair shop reprocesses the old tire into a new one and then sells it at the original price.

How to tell when a tire is a new one?


Take a look: look at the pattern and color of the tire


Look from the grain first, because inferior refurbish tire processing is not standard, so the groove is relatively shallow, and refurbish tire usually will put the tire color is particularly bright, and the regular new tire will not.


Two find: find tire identification


(1) Brand tires produced by regular manufacturers have some protruded marks on the tires, indicating the type and performance of the tires, the date of quality assurance is printed on the inside, and the wear marks in the tread anti-skid groove are clearly visible.


(2) Generally refurbished tire signs are mostly re-affixed, with nails to scratch these signs, can pull off the tire must be refurbished.


(3) At the same time, after every qualified new tire leaves the factory, there will be a special wear mark. Generally, TWI or small triangle marks will be printed on the outside of the tire. Generally, reaching this mark means that the tire loss is relatively serious, so it cannot be used and must be scrapped. The label of inferior tire after renovation was pasted by the workshop itself.


Three touch: touch the lap joint of the tread and side of the tread


First feel the tire side, all kinds of signs are complete, each tire manufacturer have forum pattern code signs, see whether the pattern code and tire pattern corresponding. Secondly, to see whether the tire shoulder tread and tire joint is smooth, refurbished tires are self-made tread sticking to the old tire, the lap joint between tread and tire side is not as smooth as the new tire, tire side has the joint trace.


(2) the hazard of using inferior spark plugs


Spark plug purchase wading deep, common maintenance shop a spark plug the cheapest ten dollars, better to dozens or even hundreds of pieces, it happened that fool some people on the Internet, still pack mail below $10, broken price.mean-while logo in one year, as a result, many ignorance of the friend is cheated, never showed in this remind you, or a failure to endanger the safety of life!


The spark plug works by converting the high voltage electricity from the pressure bag into an electric spark, which ignites a mixture of gas of gasoline and air in the combustion chamber of the engine and makes the engine start and run normally. The spark plug needs to withstand ultra-high voltage (20,000 ~ 30,000 volts), ultra-high temperature (2,000 ~ 2,500 degrees Celsius) and high-explosive pressure (50kg/cm2) when in operation.


1. The use of inferior spark plug will lead to poor material quality of the center electrode


The central electrode is not made of special nickel alloy material (there is no copper core embedded inside), which has poor thermal conductivity and is very easy to melt. The melting of the electrode may lead to damage of piston, cylinder block and other related parts.


2, the use of poor quality spark plugs will lead to poor insulation material quality


Poor conductive resistance (insulation), unable to withstand high voltage during ignition, prone to leakage, abnormal engine ignition, non-ignition, vehicle shaking and other faults.


3, the use of inferior spark plug will lead to poor anti-electromagnetic interference ability


The spark plug has no resistance and cannot resist electromagnetic interference. On the contrary, it will produce electromagnetic interference signal.


(3) The harm of using inferior helmets


For motorcycle riders, they should not buy helmets just for cheap price. Many inferior helmets with bright appearance are actually made of all kinds of waste plastic bags. In this way, to protect the motorcycle rider safety helmet, become the motorcycle rider "killing killer".

1. The shell shall be made of hard and durable materials that can absorb more impact energy; The buffer layer should be made of non-toxic and harmless materials that can absorb more collision energy and cover the head protection zone. The gasket is composed of materials such as sweat absorption and air permeability. Wear devices to ensure that the helmet and the head contact firmly; Goggles are made of materials that meet the light transmittance and impact force. The transmittance is not less than 85%.

2. Helmet weight requirements: full helmet <1.6kg, half helmet <1.3kg, left and right horizontal visual field >105°, upper visual field >7°.
