What you don't know about the shock absorption knowledge of Zhang Xueji's car

Held at the Portimao Circuit in Portugal WSBK（ In the World Superbike Championship (World Superbike Championship) in Portugal, the 820 independently developed by Zhang Xue Motorcycles RR-RS racing winning streak SSP Winning the first and second rounds of the category, achieving two consecutive championships, creating a history of Chinese motorcycle brands in top international events. It has become the focus of discussion among many domestic motorcycle enthusiasts recently, and has also attracted the attention of many laymen. We should not only see the success of Zhang Xue’s motorcycles, but also understand his ability to WSBK Some of the efforts behind winning the championship can be compared to vehicle shock absorption.

Zhang Xue Motorcycles has completed comprehensive optimization, upgrades and performance verification for the shock absorption systems of many of its models. The main aspects are as follows:：

In terms of core configuration, the damping systems of each model achieve precise adaptation. 820 RR The series is equipped with fully adjustable KYB Shock absorption, the front shock absorber supports multi-dimensional adjustment of preload, compression and rebound. The rider can fine-tune it in real time according to weight, riding style and road conditions. The rear shock absorber also has the preload adjustable function, and the inner shock absorber tube adopts DLC The coating effectively reduces friction, reduces the probability of scratches, and significantly improves durability. For the model customized and modified for flying over the Yangtze River, the front fork is equipped with an adjustable damping titanium alloy insert shock absorber, which can achieve millisecond-level switching of damping between full and empty fuel conditions, greatly easing the rigid rebound during landing. ；

The retro cruise model unveiled at the Motor Expo replaces the original cylindrical shock absorbers with exposed spring structure rear shock absorbers. It not only fits the muscular style of American cruisers, but also has better adjustment space and durability. Performance test data shows that the upgraded shock absorption system performs well in multiple scenarios. During track test drive, 820 RR The shock-absorbing system can accurately filter road bumps and provide riders with clear road feel feedback, helping to achieve a "human-vehicle-in-one" control experience.；

When testing on non-paved roads, the multi-link shock absorption of all-terrain models can effectively disperse impact forces and maintain vehicle body stability. However, the initial suspension setting of the engineering test vehicle was too soft during street driving, and the front fork stroke was compressed deeply during braking. Subsequent production versions have been adjusted and optimized to address this problem.

In the future, Zhang Xue Motorcycles will continue to rely on the advantages of Chongqing's complete motorcycle industry chain, combined with user feedback and event data, to further polish the damping response speed and continuous cornering stability of the shock absorbing system, providing a better riding experience for riders with different needs.
