Off-road vehicles, that is, cars that run on dirt roads and gravel roads on the desert Gobi Desert, have nothing to do with paved roads.
Buggy, riding on asphalt with big vibrations, poor brakes, no rearview mirrors, is dangerous and painful.
Before entering the car selection, the first thing to distinguish is the classification of the vehicle, here, the off-road vehicle is roughly divided into 3 categories.
The translation is,
Off-road on the grounds
Endurance off-road we also become forest trail off-road
Long-distance pull
Off-road vehicles are the only ones that still have two punches, such as street cars and sports cars that no longer produce two punches
The two-punch car has its own characteristics, after the speed is pulled up to open the valve, the pony becomes a wild donkey, the advantage is that it is not easy to turn off, so the veteran prefers to ride two punches when climbing the difficult section of the slope, the disadvantage is the brake, unlike the four-punch car can rely on the engine downshift braking, the novice really has to adapt to a while. However, if it is to play the forest road, many masters like two-punch cars, as if it has become a trend.
Domestic two punches: Kaixi, Hengjian
Kaixi: Wuyi Kaixi Sports Equipment Co., Ltd., the production of off-road vehicles, ATVs, two-punch off-road vehicles is also one of the more respected and highly reliable factories of domestic off-road vehicles. In the last issue, we wrote about (Kaixi 320 configuration, you can look at the past introduction: domestic two punches ~ Kaixi 320)
Kaixi is a very hardcore player in the field of domestic off-road vehicles, and the KN320 model released is positioned as a professional off-road vehicle. The two-stroke 320 is equipped with a self-developed 320 cc two-stroke engine that provides enough power and torque, and the compact and lightweight two-stroke model is ideal for it, and can provide a stronger low torque output.
The Kaixi 320 is based on KTM's 300 off-road engine base, in order to adapt to a variety of different tracks, the opening time of the mechanical valve can be adjusted, this adjustment can be adjusted with the carburetor adjustment state. The engine's compact size and astonishing power output provide the power output of its predecessors over the entire speed range, the engine weight is lighter than the four-stroke 125, and the net weight of the vehicle is 108 light, providing power and torque similar to that of the 450 cc engine. Horsepower is a staggering 62 horsepower
This model is equipped with a front-down: Taiwan HTW dual adjustable double-tube inverted hydraulic shock absorbing suspension system
Rear Reduction: Taiwan HTW Dual Adjustable Inverted Hydraulic Shock Absorber
Both the front and rear brake systems feature hydraulic brake calipers and lightweight wavy discs, ensuring braking performance while significantly reducing the weight of the discs. It also prevents the temperature generated by frequent use of the brakes and has better heat dissipation
The one-piece aluminum alloy swingarm is manufactured using a gravity die casting production process. This makes the car have better visual and handling
The CNC drum core is equipped with an EXCEL energy ring imported from Japan and a 7075 aluminum reducer handlebar to ensure the best stability with the lightest weight. And the use of PWK carburetor, aluminum waterproof switch, wheelbase 1500mm. ground pitch: 360MM and 9.5 liter tank
In terms of gearbox, the international grade and hydraulic clutch are used, making the clutch lighter and better to use, and the gears have been surface treated to improve the strength to match the improvement of engine performance.
Indulge in a journey
The KN320 is a typical lightweight endurance off-road vehicle, simple and clean, full of vitality, and the exclusive decal of the KN320 version also makes the car more layered. Just by looking at the shape, this slim model not only makes people feel no pressure, but also gives people an easy to approach affinity. However, after shaking your legs to sit, if you are thin and average, the 950mm seat height of the first 21 inches and the 18-inch tires will make your confidence greatly reduced in an instant...
In terms of starting mode, the KN320 is very pleasing with an electric start setting, and the abundant power of the lithium battery is enough to start the motor toss. But I feel that the electric start is a bit redundant, for this type of car, simple and reliable foot start is enough, compared to other two-stroke engines, this new domestic new technology to support the new two-stroke engine audible advantage is to run more uniformly and densely, the visible advantage is that the engine size is small, power burst.
Although I was mentally prepared, I was still struck by the ferocity of the KN320 while driving - the small single cylinder with a 320C displacement has amazing explosive power, and the speed of the rotational speed is amazing. It can be said that if you are not familiar with the character of the car, it is a big throttle, and the final result is that the person flips on his back, even if the power output mode is adjusted to delayed output. The engine's operating vibrations are almost negligible, coupled with the exhaust sound of the valve opening, it will make you lose your vigilance when twisting the throttle, and the rapidly gushing power will free the front wheels from gravity...
Therefore, even if you are a veteran of playing off-road vehicles, when you first contact the KN320, you can not take it lightly, you must be familiar with it lightly for a while and then gradually let go of the run, this simple and rough two-stroke engine low twist is not weak, high transformation, extremely sensitive throttle response will play the two-stroke power characteristics to the fullest, not to mention, the net weight of the car is only 108 kg. How to describe it? Beyond the power of the 400CC class, below the weight of the 125cc class, with the performance of the car.
Obviously, the KN320 is a model that you need to take seriously, whether the ferocious power output exceeds the <国内>high-end configuration of the same level, as well as the flexible performance of the lightweight body, it will exceed your expectations. And the premise of you owning it is not only money, but also the strength to control it. In fact, this is a lightweight model that is extremely convenient to control, especially the setting of the turning radius, which will make you turn casually and freely in the tight forest, and the suspension system and performance will not be necessary to waste pen and ink to say anything...........
In short, the KN 320 is a "fierce horse", you have the strength to tame it, in order to enjoy the passion of driving...
Let's discuss briefly:
Because the lubrication environment when the engine is working is indeed worse than the four-stroke is indeed indisputable, but why do so many people say that it is easy to pull the cylinder and burst the cylinder? It has its own mechanical properties, do you operate according to its mechanical characteristics? According to the manufacturer's standards (we ordinary players can take a longer time) to maintain and replace pistons, piston rings and other most basic consumables? Naturally you don't respect it, and it will play a temper with you ~ so a strike is a normal thing. Some good foreign cars are scrapped in the country for one or two years, and some are broken and dismantled in three or four months to sell or shi body cars to sell.
Maintenance and driving style
First of all, the two-flush car has high requirements for burning engine oil (I have seen some riders also use four-flush engine oil as burning oil ~ it is really not advisable), and the fuel blending ratio is also changed due to the different driving styles of each person. There is no need to blend too much in the combustion oil (I see that some riders use the fully synthetic combustion engine oil to blend the ratio of 25/1), because the vast majority of car owners now buy semi-synthetic or fully synthetic. There is also the driving mode is consistent four-stroke driving mode is not advisable, can not be a long time under a small load in the case of high rotation (in order to output torque short time appropriate gear with load high rotation is no problem).
The quality of the product or a certain batch of products is defective
I know, at this point, someone wants to spray me again, probably because I am writing a domestic car, whether imported or domestic will have more or less quality problems (because after all, they are industrial products), defects or quality can only be said to be a matter of probability. There is also a distinction between materials and manufacturing processes, so the universal interchange of some car accessories does not mean that the performance is similar. Good genes are not interchangeable or generic.
There may also be people who compare it with the KTM300, so let me ask, in terms of price, have you made a comparison? Do you go to see how KTM costs? See how much this KN320 costs? If you feel afraid of the problem and afraid of this and that, then I suggest that you directly change the imported car or do not ride,
Of course, the problem of the vehicle is not the most terrible, the most terrible is the manufacturer's irresponsibility, what we need is an attitude of the manufacturer, the problem is normal, but to be able to solve the problem.
Manufacturer guidance
Notes:
1: The new car oil gasoline ratio is 1:40 before ten hours, 1:50 after ten hours, please strictly follow the correct proportion of oil to recommend american horse K2927 two kinds of oil
2: Please change the gear oil after 10 hours Recommended 10W40 (summer) 5W30 (winter)
3: After the new car is received, check the screws of the key parts before using it, because it is a two-flush non-road car, so it is also necessary to check the screws regularly afterwards.
4: Check the tightness of the chain adjusted to a suitable distance of 25-30MM before each use and check whether the chain interface is well connected.
5: Piston piston environmental protection time is recommended to replace and maintain for 100 hours.
6: Not suitable for road and desert use
