Riding a motorcycle who will, but when it comes to car maintenance and parts selection, a lot of senior Mo friends seem to be small white. Motorcycle parts are many, knowledge is very wide, in the motorcycle parts competition market, there are inevitably some black merchants, sell some inferior products, some important parts and protective parts, in the purchase of distinguish between good and bad and important, good zero protective parts can ensure your safety, poor zero protective parts minutes to your life! How to measure the severity of these hazards, it depends on how important you look at life, the following three motorcycle accessories, the key time may be related to your life, teach you to distinguish the advantages and disadvantages of their products.
(1) the harm of using inferior retread tires
If any motorcycle accessories will be related to the safety of Moyou, it is estimated that nothing is more important than motorcycle tires.
However, there are still a lot of profiteers in order to pursue profits regardless of the life safety of friends of motorcycle, actually selling retread tires, friends in the purchase of motorcycle tires to a little bit longer heart, eyes to see clearly. There is a friend abroad met such a bad luck, the guy riding a tire just changed not long motorcycle on the road, open not long, tire instant peeling caused motorcycle slip tire fell car, back skin abrasion blood flow.
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 skin off the surface is a scrap tire, the grain is worn out. It is estimated that the motorcycle repair shop reprocessed the scrap tire into a new tire, and then sold it at the original price. In fact, retread tires are very common, many motorcycle shops to help customers replace the tire, will be put away the tire, and then processed for sale, not only motorcycle tires, car tires and bicycle tires are like this, so you should be careful when changing tires.
Teach you three tips how to tell whether the tire is a retread tire?
1. Look: Look at the pattern and color of the tire
First from the grain point of view, due to the inferior refurbished tire processing is not standard, so the grain groove is relatively shallow, and the refurbished tire usually put the tire color whole especially bright, and the regular new tire will not.
2. Find: Find the tire logo
(1) the brand tires produced by regular manufacturers have some protrudes on the motorcycle tires, indicating the model and performance of the tires, and the inner side is printed with the warranty date. The wear mark in the tread anti-slip groove is clearly visible.
(2) the general signs of retread tires are mostly repasted, scratch these signs with nails, can cut off the retread tires.
(3) At the same time, each qualified new tire will have a special wear mark after leaving the factory. Generally, the outside of the tire will be printed with TWI, or small triangle logo. Generally, reaching this mark indicates that the tire is more serious wear and tear, can not be used, and must be scrapped. And the inferior tire mark after renovating is workshop affikes oneself.
3. Touch: touch the lap between the tread and the side of the tire
First feel the tire side, whether all kinds of marks are complete, each tire manufacturer has the forum pattern code mark, see whether the pattern code corresponds to the tire pattern. Second, look at the shoulder of the tread and the joint of the tire body is smooth, refurbished tires are homemade tread on the old tire body, the lap between the tread and the side of the tire is not as smooth as the new tire, tire side has a combination of traces.
(2) the harm of using poor quality 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, just 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, Otherwise, failure will endanger life safety!!
The spark plug works by converting the high voltage electricity from the barb into an electrical spark that ignites a mixture of gasoline and air inside the engine's combustion chamber, allowing the engine to start and run normally. When operating, 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).
1, the use of poor quality spark plug will lead to the center electrode material is poor
The central electrode is not made of special nickel alloy material (there is no copper core embedded inside). It has poor thermal conductivity and is very easy to melt. Melting of the electrode may cause damage to the piston, cylinder and other related parts.
2, the use of poor quality spark plug will lead to poor insulation quality
Anti conductive performance (insulation performance) is poor, can not withstand the ignition of high voltage, prone to leakage, engine ignition is not normal, no ignition, vehicle jitter and other faults.
3, the use of poor quality spark plug will lead to poor anti-electromagnetic interference ability
The spark plug has no internal resistance and cannot resist electromagnetic interference. Instead, it will generate electromagnetic interference signals.
(3) The hazards of using inferior helmets
For motorcycle riders, buying helmets should not only be cheap, many of the low-quality helmets with a bright appearance are actually made from all kinds of waste plastic bags. In this way, the safety helmet, which is used to protect the biker, becomes the "killer" of the biker.
Most MOfriends do not know what the safety standards of Motorcycle Rider Helmet are, which helmet brands are trustworthy, and what kind of helmet is a good helmet. Therefore, consumers tend to follow blindly in the choice of helmet, which is not rational. Cheap, good-looking and comfortable helmets are the priority, not safety.
For your own safety and that of your family, do not buy or use inferior fake motorcycle helmets. Here are some easy ways to identify motorcycle helmets:
1, the shell is made of hard, durable, can absorb more impact energy materials; The buffer layer should be made of non-toxic and harmless materials that can absorb more collision energy and can cover the head protection area; The gasket is composed of sweat absorbing and breathable materials. Wear devices to ensure that the helmet and head contact; Goggles are made of materials that meet the light transmission performance and impact force, and the light transmission rate is not less than 85%.
2, helmet weight requirements: full helmet<1.6kg, half helmet
3. The helmet must have a fixed logo, such as product name, manufacturer name and address, trademark, product type, product model, specification, production date, product batch number or serial number.
4. The helmet is divided into three sizes according to the head circumference: large 580~600mm, middle 560~580mm and small 540~560mm. When choosing a helmet, you must choose the appropriate number according to your head circumference.
5. The helmet should be stopped after a large impact accident
When choosing the helmet, you should also pay attention to it. You should hold both sides of the helmet with your left and right hands, and then rub your head left and right to wear it. On the contrary, when taking it off, you should try to shake it back and forth after wearing the helmet to see if the size is appropriate. The helmet weight can not be weighed by hand, the correct way is to put on the head, if the neck does not feel heavy on it.
