Yingang National IV Ninety Test Review
The retro bike marks the old fashion. In recent years, some manufacturers began to redefine the retro bikes, which integrates technological elements into the traditional retro models, but there are also some “hardcore” enterprises who stick to the pure heart of vintage motorcycles, striving to restore them from appearance, configuration, performance and feelings. Yingang ninety (YG200-8C) is one of the masterpiece among the pure retro models.
It tells you with every detail what is a hardcore retro bike: a retro appearance, exposed structure, deep and restrained color scheme, water drop tank, halogen bowl lamp, oil-cooled engine, steel wire spoke wheel, sawtooth tire, rear double shock absorbers, exposed steel tube frame and suspended engine.
As for the lighting system, the front lamp of ninety is a bowl-shaped halogen lamp, and the turn light is designed with an orange shell and a silver-plated back cover, and the tail light is an LED light.
Instrument is a single and round one, integrated with mechanical and electronical function.
The matte black water-drop shaped tank has a capacity of 12L and supports a comprehensive cruising range of up to 400km.
The caterpillar type flat retro cushion is comfortable. The U-shaped armrest provides good support.
In terms of power system, ninety carries YGF Ⅱ generation of vortex combustion balance shaft engine with a maximum power of 10.0 kW / 7,000 rpm, a maximum torque of 15.0 N·m / 5,500rpm, and a top speed of 98 km/h.
It is upgraded from air cooling to oil cooling that significantly improves heat dissipation. With Delphi EFI system, it not only meets the requirements of environmental protection but also ensures smoother power output.
This engine has undergone rigorous market validation, and its performance is mature and stable. At the same time, Yingang has made targeted adjustments to the riding habits of retro models. The overall performance is reliable.
Ninety carries a front inverted shock absorber, with an effective stroke compression of 112mm. The damping is proper with good rebound resilience. The rear double airbag shock absorbers are with the airbag nonadjustable. Overall, the shock absorption is proper for riding in the cities to deal with roads with small potholes while providing clear feedback on the road conditions.
The National IV Emission Standard edition of ninety adopts the high-quality Cheng Shin tires, and has 17-inch black steel wire wheel hubs as a standard component. The tire has a better R guide angle and a better road holding ability.
For the braking system, ninety has standard front and rear round single disc brakes. The front brake responds sensitively, while the rear brake feedback is relatively soft but adequate. In addition, the National IV edition ninety is also added with CBS that improves the safety coefficient, which reflected that Yingang pays special attention to riders’ safety.
According to the actual riding experience, CBS has an excellent performance. Applying the rear brake gently to slow down on a downhill slope, there is no front or rear wheel skidding, and its overall performance is stable.
The outline dimension is 2,050x750x1,040mm. The wheelbase is 1,360 mm. The minimum ground clearance is 200mm. With a seat height of 780mm, a rider of 170cm high can touch the ground easily on both feet. Thanks to the light body and excellent handling, the bike is easy to operate for small fellows.
Ninety adopts the international five-speed transmission. The N gear is gentle to engage in, and the power output is stable in the 1st gear. Shifting from the 1st gear to the 2nd gear is smooth and comfortable. After 3,000rpm, the power starts to increase at a uniform speed. From 2nd to 5th gear, the gear shifting is still comfortable and the overall performance is satisfactory.
Ninety’s vibration control is excellent. When it approaches the top speed, there is still no strong vibration, only slight vibration at the handlebar, and no arm numbness during long-term riding.
During urban riding, the acceleration is strong while riding at 40~80km/h, which is completely enough for use for urban commuting and short distance traveling.
Ninety shows better curve performance than common retro models, particularly while entering a curve — the rear tire has reliable road holding ability and good shock absorption relieves the rider from worrying about a rear wheel drifting. At the same time, the engine bursts strong power at 4,000rpm to 6,000rpm to make the entire curve riding process smooth and pleasant.
When testing the climbing performance, the 20° slope is easy for ninety to climb up whether at a high speed or low speed.
Ninety showed good performance in the complex road conditions, thanks to the good shock-absorbing tires, shock absorbers as well as the proper adjustment of Delphi EFI system. It can still maintain a good riding posture even while riding slowly with a passenger on, no worrying about touching the ground to keep balance or inaccurate throttle control leading to flameout.
In nearly 20 minutes’ test riding, ninety has been in the high intensity state of repeatedly switching between high and low speeds. Thanks to the oil-cooled system, the engine’s temperature does not increase abnormally, and the heat was controlled within a proper range.
For such a retro bike that sticks to the original aspiration, Yingang ninety can easily arouse a deeper resonance in the riders’ heart with both its appearance and internal details. This is Yingang ninety, a pure hardcore retro bike. (Source: WeChat: M-INFO)
