Last summer, we got the GPR250R prototype version first, and also brought a comprehensive evaluation and track experience of the car to the riders for the first time.
Although this imitation small steel cannon was released at the Xi'an Motorcycle Expo, the manufacturer waited for a long time before it was officially released in the near future. The reason is that naturally the first batch of test media for everyone to be a guinea pig, the manufacturer through our test feedback, collected a large number of modifications, the vehicle state continues to polish and improve.
Just after the Arrival of the New Year, we also received a free shipping "express" from Foshan again - the mass production version of GPR250R.
I haven't seen him for half a year, and I miss it very much. Waiting for a long time is a greater improvement in details.
Although it seems that there is only a slight difference in the decal from a distance, after getting closer and getting started, the details of the GRP250R have improved to a higher level. This article focuses on adding the differences between the prototype GPR250R half a year ago, and the same part will not be repeated.
First of all, the power part, the factory told us that although the appearance of the GPR250R engine is no different from before, it has been re-optimized in the process, and the engine running quality has been improved to a certain extent.
Of course, no matter how the single-cylinder engine is optimized, the vibration sensation is still relatively obvious. Although there is a clear sense of grain at low speeds, the amplitude of the optimized 250cc ARC engine does not increase significantly when it continues to increase the speed, but the frequency gradually increases with the throttle. So in the high-rover part, the GPR250R's running quality is better, it seems to indicate: come on, if you want to cool, don't loosen the throttle.
The most typical change occurred in the windshield part of the front of the car, when we proposed that the windshield material was too soft and the back of the instrument was exposed, which was completely solved on the production car. In addition, after the windshield was changed from transparent to translucent black, the speed warning light on the instrument was more eye-catching when leaning down to accelerate.
The production version of the GPR250R front wheel fender and the side panel surface under the saddle have been modified from simple matte black to imitation carbon fiber embossing, which also makes the whole vehicle more process texture and sports atmosphere.
In the previous test, we have said that the GPR250R instrument has a speed reminder light and navigation projection function, Xiaobian believes that the more practical function of this instrument is still the custom display bar under the main interface.
In order to adapt to the most intelligent and information-rich instrument at present, the GPR250R mass production version abandons the original set of universal handlebar switch assemblies. The new switch assembly not only improves the feel of the keys, but also adds a set of three-dimensional arrow keys, which is easier to understand and more user-friendly to interact with the instrument. Now you can switch the speed/mileage and AB time, top speed and fuel consumption displays in the custom display area by directly flicking the left-handed switch switch on the left-hand handle switch.
Regarding the main update of the GPR250R mass production version, we will first say here, in fact, there are many details such as shell seams, clamping lines and other places have been optimized accordingly. Overall, the previous test sample car is still lacking in terms of completion, and the current updated mass production version has made up for the lack of texture before, the image is a little metaphor, the current GPR250R is more "aprilia".
At present, many physical stores have already arrived at the store, you may wish to explore the status of the new mass production car for yourself.
Attentive riders will find more than one GPR in our pictures. Yes, the manufacturer "buy one get one free" also shipped a factory car used in the "GPR Unification Race".
At present, the domestic lightweight imitation racing market has become more and more hot, whether it is a joint venture brand or a number of domestic independent brands, whether it is a single cylinder or a double cylinder, the range of choices for riders is becoming more and more abundant; in fact, the real selling point of the imitation racing model is inseparable from the word "race", the real hardcore in this level of models, really has a strong competitiveness on the track, GPR250R is still unique. Starting with the 125-era GPR/RS4, the series has accumulated a lot of data on the track, and then continuously optimized and improved the frame and suspension system according to this continuous optimization. From this GPR250R factory car, we were able to find some of the modification experience that is already being applied on the track for GPR owners.
As a racing car rather than an imitation race, the GPR250R must first eliminate some of the parts that affect safety or excess on the track, such as rearview mirrors, side braces, lighting systems, occupant pedals and ABS systems, which not only do not play a role on the track, but even cause safety hazards in the event of a fall and affect other vehicles competing in the same field.
Tires are the first step in the transformation of racing, GPR250R factory racing car with SR10 competitive tires from Zhengxin CST, this tire has been widely used in larger displacement cars such as 600cc, participating in large events and continuously improving the formula can allow tires to quickly enter the working temperature; track tire design and single wire jointless technology to ensure the overall support and stability under high lateral loads in the track.
It is worth noting that the front and rear tire dimensions on the GPR250R factory car have been modified from the production version of the 100/80 R17 and 130/70 R17 to 100/70 R17 and 120/70 R17, reducing the overall size by a size. On the one hand, this reduces the weight of the wheel group, reduces the rotation inertia and makes the body tilt more agile; on the other hand, the diameter of the wheel group is reduced and the actual torque on the wheel is increased under the condition of the gearbox gear ratio is unchanged, and the car is more energetic and accelerates stronger. But on the other hand, the larger tire thickness of the mass-produced GPR250R can provide better cushioning capacity for race track tires, after all, the use environment of street pavement is much more complicated on the race track.
The front shock absorber of the factory racing car uses a set of FFC-250T fork core from the special suspension system modification manufacturer GEARS in the United States, using aluminum alloy lightweight inner tube and silicon chrome steel lightweight spring to reduce the sub-spring mass of the shock absorber, and most importantly, it has preload, compression damping and rebound damping adjustment function, which can be easily adjusted to the best working state according to the rider's weight and driving habits, reduce the body shaking caused by the over-bending action and acceleration and deceleration center of gravity transfer, and provide the most stable track support feeling.
The adjustment of track shock absorption is based on the continuous repeated testing-communication-re-adjustment of the maintenance mechanics and drivers, which is separated from the single use environment of the track, and it is somewhat impractical to require ordinary users to constantly adjust the vibration damping settings.
The rear damping also comes from GEARS, and the external cylinder shock absorber of this model, THEHILL-2 PLUS, also has preload, compression damping and rebound damping adjustment. At present, the official online store of Aprilia has opened a pre-sale of these two GPR250R special modification shock absorption, although the price is not cheap (about 12k), but after all, they are Racing-level.
For faster gears, the Quick Shifter Module, commonly known as the Quick Shifter Module, also appeared on the GPR250R factory car. The absence of clutch operation when shifting gears is only one of the functions of the fast row, the most important thing is that it can significantly reduce the time required to change gears, so that the work of the engine can be smoother and continuous when accelerating.
The fast-paced supplier of the GPR250R race car is Pointer Technology from Hong Kong. The handless aesthetic cut of the (Pointer Racing) engine cover is due to the fact that the cars are all reverse gear settings, so that the rider can quickly upshift with the lower pedaling action.
VANHOOL Jiehui Wanhu Exhaust is a Guangdong modified exhaust brand founded in 1995 in 2009, most of the early stages are oem-based OEM of European and American manufacturers, after accumulating enough experience in high-performance exhaust system tuning and production, it began to launch its own brand for the domestic market.
It was only natural that Foshan-based Zongshen Piaggio chose VANHOOL as the co-brand of exhaust systems for the GPR250R factory car. Unlike the straight-through exhaust that everyone imagines, this titanium exhaust that is tuned for this 250cc ARC engine still retains the full-section back pressure chamber design, allowing the GPR250R factory car to have a smoother engine response while maintaining a fairly good mid-section torque.
For the average rider, racing seems far away from us, but when you think about it, it's not. Since the GPR car series entered China, Zongshen Piageo has spared no effort to promote the development of domestic motorcycle sports, and the activities of "GPR Circuit Academy" and "GPR Unified Race" have emerged a group of talented racing teenagers represented by Zhang Xuhao, who is only 14 years old.
As the closest stepping stone to our approach to motorsport, the GPR250R does offer more possibilities. If you are still fighting, why not try it, whether you are that piece of material!
