More design highlights that impress you at first sight

Exquisite style

In order to achieve a sense of unified entity, the whole motorcycle adopts the design of screw-free installation. The soft sponge of the cushion which is formed into a sharp angle through the advanced internal foaming technology connects with the gasoline tank seamlessly. The assembly clearances of all covering parts are less than 0.5 mm. The premise of such process requirement, which is even rarely seen in the automotive field, is that the deformation amount of the frame after welding is almost zero.

Distinctive characters

Ingenious headlamp with cover

Transformer appearance The LED design is adopted for all lamps of the motorcycle, reducing the storage battery load and improving the penetration length in the dark. The ZT250-S headlamps can greatly lower down the lighting efficiency attenuation of traditional lamps after long-term usage.

Pretty color assortment

In order to avoid the discoloration and the peeling off of the applique due to sun exposure, split-type parts are designed, painted separately and combined as an integrated part for areas on ZT250-S which should be appliqued, which not only is texturally beautiful, but also makes it easier for consumers to change their favorite color combinations.

High-tech gasoline tank design
	Double galvanized sheet inner gasoline tank The inner liner is made by double-layer galvanized sheet to prevent the gasoline tank from rusting.
Elaborately developed dull polish paint The dull polish paint developed for ZT250-S for 3 years is much more resistant to oil and corrosion than other varieties in the market, and sprayed by robots under the sealed environment during the whole process only for the distinctive colors which are unforgettable.

360-degree positioning rotary rearview mirror

Cyclists won't be bothered by constantly adjusting bilateral symmetry for the rearview mirror thanks to the ingenious 360-degree positioning rotary design.

All-liquid crystal display intelligent digital controller
	Intelligent digital controller Fashionable and distinctive speed indicators are progressively-arranged on the all-liquid-crystal intelligent digital controller which is clear at a glance. The traditional mechanical front wheel speed line output structure is abandoned, and the intelligent processing based on the advanced electronic sensor combined with the controller chip is adopted, which not only can display accurately and react fast, but also is more dust-proof, waterproof and weatherproof.
Central control anti-theft lock The central control anti-theft lock with integrated design located in the center of the motorcycle head can open and close the gasoline tank cover and the anti-theft lock cover, and operate the front lock, the seat cushion lock and the ignition switch, which is very convenient for usage.

Cyclist-centric design concept
	Comfortable cushion Compared with the traditional process that the sponge is formed and then wrapped by the outer skin, it is a breakthrough to adopt the advanced technology that the outer skin is formed and then filled with the sponge foam. This kind of angular and exquisite cushion neither wrinkled nor deformable, is a configuration which is only possible for the imported motorcycle with a price over RMB100,000.
Central rear shock absorber The design of built-in air bag filled with high pressure nitrogen is adopted for the central rear shock absorber to reduce the hydraulic oil temperature; it can provide greater restoring damping force when cycling at high speed, while the high-pressure nitrogen in the air bag can also change the air spring characteristics inside the shock absorber; improve the cycling comfort and the feeling of fatigue during long-distance travel.

Super-wide tire

The wide tire is an important symbol of the racing bike. The 150 wide tires with a flat rate of only 55 are standard configuration for ZT250-S, which is even rare for modified motorcycles on the racing track. The weight is significantly reduced by the hollow aluminum alloy wheels, which improves the startup acceleration performance. Both the front and the rear tires are special radial tires for the racing track, with good road holding and anti-deformation performance.

Fully-automated robot welding

The fully-automated robotic welding combined with low-spatter fusion welding technology which not only eliminates the welding deformation of the frame, but also makes the internal of the tube clean and slag-free, forming a clean and natural engine gasoline tank for ZT250-S.

Strong power

High performance oil-cooling engine


Based on the concept of high performance and fuel economy and durability, a low-speed and high-torsion oil-cooling engine is tailored for ZT250-S. When the engine runs at a low speed of 5,000rpm, the motorcycle speed can be up to 85km/h. and the economic fuel consumption of 100km at a constant speed of 60km/h is only 2.8 liters. The emission of ZT250-S can easily meet the high standards of TUV EU certification thanks to the double overhead camshaft four valves with the Delphi EFI system which significantly improve the motorcycle's startup performance at low temperature, obtaining authentication certificate from the German Ministry of Transportation.	The traditional mode of lubrication that the lubrication oil is splashed by the gear is replaced by the mode of injection lubrication that areas which should be lubricated are directed sprayed by the high-pressure oil through the oil pump thanks to the unique dual-oil-pump design. After that, the hot oil in the engine is pumped into the frame for external circulation of heat dissipation, which reduces the engine temperature to a greater extent and significantly extends the engine life. The ZT250-S engine adopts the technology of all-aluminum cylinder without liner, which enables homogeneous-material thermal expansion amount between the cylinder wall and the piston, thereby eliminating the noise of the piston striking the cylinder wall after the warm up process; the ultra-thin cylinder wall is also more conducive to heat dissipation. New designs, such as the built-in balance shaft, the external engine oil strainer, the low-damping air filter, and the stainless steel silencer, etc. redouble the highlights of the super ZT250-S engine.

Why does the Shengshi ZONTES 250-S engine speed up fast?

ZT250-S engine

The running resistance of the components is very small because there is no engine oil sump in the gearbox of the ZT250-S engine. It greatly improves the acceleration performance, which is the "dry oil sump" design that only the motorcycle on the track has. The principle: after the motorcycle is started, the scarce engine oil in the gearbox is pumped out by the oil pump A immediately, and enters the frame pipe for circulating heat dissipation. The cooled oil after heat dissipation is pumped back to the countless injection channels specially designed for the engine by the oil pump B, and sprayed at each part for heat-removing directly like the shower head.

Ordinary engine

Components operated inside the ordinary engine gearbox are immersed in the engine oil sump. The running resistance is extremely large due to the viscous nature of the engine oil, like running in the water, which is slower than that in air. The oil is more viscous and the engine acceleration performance will be significantly impacted, especially in the winter.
