March has arrived, Chunfeng new SR model as promised, today Chunfeng released the latest version of 250SR, but also the single rocker arm version that everyone is most looking forward to, Chunfeng called the 2022 track version, priced at 21980 yuan, only 300 pieces more expensive than the 2021 track version, too fragrant!
The Chunfeng 250SR single rocker arm version can be said to be the "ultimate version" of the 250SR that domestic riders are most looking forward to, basically giving everything that should be given at this level. Whether it is appearance, configuration, power or pressing, almost all of them are arranged in place, and the competitiveness of the 250SR has reached an unprecedented height.
The single rocker arm is the focus of the 2022 Track Edition upgrade and the most compelling configuration in appearance. This single rocker arm not only breaks the shackles from the structure, but also has a qualitative increase in rigidity. The bending stiffness is increased by 89%, the torsional stiffness is increased by 97%, and the weight of the vehicle is reduced by about 3.2 kg. By reducing the total weight of the frame and tires by 8 kg, the curb weight was reduced to 157 kg.
Another change in appearance is the dingfeng wing, as a domestic 250-class sports car is rarely equipped with a fixed wind wing model, the 2022 track version of the 250SR after adding "small wings", so that the sense of combat of the whole car soared rapidly, and the original fixed wind wing does not exist in the embarrassing situation of being judged to be modified.
The new model has also been upgraded for the instrument, the new TFT fully fitted instrument provides a brightness comparable to the mobile phone screen, in the strong light can also clearly see the screen display information, recognition has been improved a lot, but also through the APP projection screen to achieve simple navigation function. With the 2nd generation T-BOX, it brings a better human-computer interaction experience.
The power part, or the 249cc displacement single-cylinder water-cooled engine, comes standard with a sliding clutch. However, compared to the existing model of the 250SR, the power is increased by 5%, the maximum power is increased to 21.5 kW, and the peak torque is increased to 22.5 N·m. Combined with a lightweight new design, it brings a more interesting driving experience.
Other changes include an increase in rear disc diameter to 240mm, which improves rear brake performance. The upgraded rear shock spring has increased stiffness, reduced damping and better support. The new model has also improved the vibration suppression, coupled with the structural adjustment of the plastic parts, which has greatly improved the abnormal noise during the ride. The well-received KYB front and rear suspension on the track version has been retained, as well as the dual-channel ABS.
In the face of the fierce competitive environment in the 250cc sports car market, Chunfeng launched the track version of the 250SR in 2020, and evolved again this year according to the opinions of riders, launching a stronger 2022 track version of the 250SR, completing a comprehensive upgrade of nine rises and one drop, and the competitiveness is stronger.
