I'm a rider to share, don't blow or talk about motorcycles.
It's on fire! The video of Mr. Wei Jianjun, the boss of the Great Wall, riding a happy XF250 motorcycle and walking around the closed road in the village, has become a hot topic among riders, and many people's thoughts and memories have been hooked up at once, and they have instantly returned to the era of recording the bits and pieces of life.
It is reported that the XF250 in the video is a motorcycle bought by Mr. Wei of the Great Wall in 1984, which has a history of more than 40 years and can be called a classic car in the motorcycle industry.
Some people say that this car is well maintained, and that is of course, for a motorcycle friend who has both feelings and strength, it is not a myth to maintain his former car properly.
Even ordinary individuals can do it as long as they have some conditions, and there is no shortage of such classic cars in real life.
The original version of the Happiness XF250 motorcycle was launched as early as March 1960, and it has gone through 35 years and has undergone many upgrades.
It was the model with the largest number of ownership and the highest localization rate of the whole vehicle at that time. The XF250A generation and Beijing Jeep were the standard and official cars of many units in that era, and there was also the Yangtze River 750.
Modern version of JAWA250
XF250 is a domestic motorcycle from Shanghai No. 2 Bicycle Factory (renamed Shanghai Motorcycle Factory in 1964, acquired by Mr. Zhou Yichu, a private entrepreneur in 1985, and named Shanghai Yichu Motorcycle Co., Ltd., and then went to the road of hanging) by imitating the Czech JAWA250, it should have five versions from the original version, and it is said that there is also an electric start version, but I have not seen it.
One of the most classic is the "ant head" that is, the happiness XF250A generation, the car covers the iron shell, in addition to tires, rubber sleeves, exhaust pipe joints, rearview mirror covers, turn signal lamp covers, almost no rubber plastic parts.
Therefore, even if you crash, there will be no damage, it is nothing more than a scrape of sheet metal parts, but the strange thing is that judging from the road conditions at the time, there will not be much damage, so it is very durable.
By today's standards for judging motorcycle style, the XF250A is a very typical retro street bike, with a simple and atmospheric shape, no excessive decorative elements, and the simplest rounded attributes to outline the full picture of this extreme retro car, even if it seems to be not outdated now. Of course, the original version is more meaningful.
The car is equipped with a 250 cc single-cylinder two-stroke air-cooled engine, which has an actual displacement of 248.5cc, a maximum power of 8.3KW, a maximum design speed of 110km per hour, and a fuel consumption of 2.5~3.5L per 100 km. It adopts carburetor fuel supply mode, battery cam platinum contact ignition, supporting reciprocating four-speed gearbox, chain transmission system.
The way this car shifts gears is very skillful, because it is completely reversed from the current international gear, which belongs to the "one pick and three steps", and you can find a neutral gear in the middle of each gear.
Of course, this is not the special design of the gearbox, but the gear gap itself is a bit large, so many riders at the time liked to "coast in neutral". It may be that the driving habits of some old drivers are formed from this car.
Here's a knowledge point. Although the XF250 is a manual clutch non-automatic transmission, it can be changed without pinching the clutch during the shift after starting.
Because there is a clutch pushrod paws reserved on its gear shaft, the clutch can be automatically disengaged the moment you press the gear lever, and then cooperate with the action of closing the throttle to smoothly achieve a smooth upshift without frustration.
In addition, the starting lever and gear lever of the car are one, press it in and pick it up, and then step on it, and the motorcycle will start. However, this ritualistic process also needs the blessing of technology, otherwise it is easy to get injured, even if you are powerful, you may not be able to start smoothly.
In fact, there are many details about this car, because I am too familiar with it, XF250 motorcycle can be regarded as my industry leader, it is its huge market holdings, so that I have the opportunity to practice maintenance skills, and then form a set of relatively reasonable fault identification methods and maintenance programs, so this issue is here first, and later I have the opportunity to talk about it and some personal stories.
