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.

Wonderful technology and brilliant design

Full core quality and ultimate experience

Keyless control system The carry-on keyless system transponder can unlock the motorcycle through inductiveness within 1.5m from the motorcycle (the transponder can be placed in a backpack or pocket, and the cyclist doesn't need to take it out), and vice versa when the transponder is outside the range of 1.5m from the motorcycle. It is simple and convenient, which eliminates the cumbersome of using key to unlock the motorcycle. The whole motorcycle adopts the electronic lock, which presents the cyclist more wonderful experience.

Electric function

The electric gasoline tank cover, the electric cushion lock, and the electric motorcycle head all make the traditional keys seem pallid by comparison. The buttons are distributed on the left and the right handlebars, which facilitates the cyclist to press at any time.

New rubber pedal The air-cored rubber pedal is used to block the transmission of vibration onto the sole of the foot.

Central nitrogen 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 during cycling at high speed,

and the high-pressure nitrogen in the air bag can also change the air spring characteristics inside the shock absorber. The overall design is comfort-oriented, the spring preload is small, and the movement stroke is increased; improve the cycling comfort and the feeling of fatigue during long-distance travel.

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-R.

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.
Integrated inner water baffle and chain case cover The splash-proof function is greatly improved.

Uniquely designed rear license plate bottom case

When the license plate bracket is installed on the rear water baffle, the original bracket mounting hole under the rear seat can be sealed, which is beautiful and seamless.

Readjusted and recalibrated engine

It is smoother at medium and low speeds, with lower vibration, lower fuel consumption and longer endurance mileage at higher speeds.


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-R. 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-R 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-R 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-R engine.

Start the mechanism of decompressor The motor load is higher when the engine without a pressure reducing valve is started. When the engine with a pressure reducing valve is started, the top column of the closed pressure reducing mechanism opens the exhaust valve slightly, and the start-up mechanism does not need to compress the gas in the cylinder. The start-up load is smaller and it is easier to start the engine. When the engine roars, the pressure reducing valve is open and the top column is retracted, which does not affect the normal operation of the engine. Advantages: the startup resistance of the engine, the abrasion of the parts of the startup mechanism, and the energy consumption of the instantaneous power supply of the storage battery are reduced, and it is easier to start up the engine under the cold state.

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

ZT250-R engine

The running resistance of the components is very small because there is no engine oil sump in the gearbox of the ZT250-R 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.
