Description
You wanted a big street - here's a big street for you.
This is an ultra-modern enlarged street bike and it is much larger than its younger brother - the CR6z model.
In size, this bike can be compared to the popular street from Benelli TNT300 or its updated version 302s.
That is, Geon Stinger 250 - full-size, "large" and is suitable even for people of outstanding size. Such a medium-sized "hyper-Naked". Although for a short rider Geon Stinger is also suitable. Because Geon Stinger is a street bike and its landing is not high, and the ergonomics are classic.
Its design is painted in a very modern faceted style with clear lines and a moderately aggressive expression of the headlights.
Engine and cooling
The main feature of this motorcycle is the engine - it is unique and very technological.
The engine has a total of 249 cubic meters. In terms of power, the Geon Stinger motorcycle is much superior to most oil-cooled 250-ok, and has a light weight. This gives the motorcycle incredible handling and balance.
The designs of a head of the block of cylinders, the piston, a connecting rod, a cranked shaft developed on modern technologies considerably reduce vibration and noise of the engine. The lightweight mechanism of the cylinder head significantly improves the acceleration characteristics.
The engine is redesigned based on the concepts of high performance, fuel economy and durability. Fuel consumption per 100 km is only 2.8-3 liters.
The environmental standards of the engine meet high standards, thanks to a double upper camshaft with four valves and a modern carburetor with a flat throttle, which significantly improve the performance of the engine as a whole.
The Stinger 250 engine uses the technology of an all-aluminum cylinder without a sleeve, which provides uniform thermal expansion of the material between the cylinder wall and the piston, thereby eliminating the noise of the piston against the cylinder wall. And the thin wall of the cylinder increases the efficiency of heat dissipation. The engine runs very quietly and smoothly.
In addition, there are such features as a built-in balance shaft, external engine oil filter, low-resistance air filter.
Lubrication system
This engine uses a channel pressure lubrication mode, in which oil is supplied to the areas to be lubricated through a high-pressure oil pump, thanks to the unique design of the double oil pump. After that, the hot oil in the engine is pumped into the frame for external heat transfer, which significantly reduces the engine temperature and extends the life of the engine.
Advantages of a dry crankcase
The running resistance of the components is very low, as there is no oil bath in the gearbox of the Geon Stinger engine. This significantly improves the acceleration characteristics - the design of the "dry sump". While components running inside a normal engine gearbox immersed in an engine oil bath meet additional viscous oil resistance. And this significantly affects the consumption and acceleration characteristics of the engine, especially in winter.
Starting mechanism with decompressor
The load on the engine is higher when the engine is running without a pressure reducing valve. When starting the engine with a pressure reducing valve, the system slightly opens the exhaust valve, and the starter mechanism does not need to compress the gas in the cylinder. The starting load is less and the engine is easier to start. Advantages of this solution: the starting resistance of the engine decreases, wear of details of the starting mechanism decreases, and also power consumption of a power supply - the storage battery decreases, and it is easier to start the engine in a cold condition.
Cooling system
Geon Stinger 250 has a very advanced and efficient oil cooling system. The frame is part of the engine cooling system - engine oil is pumped into the frame to remove heat. At the same time the big radiator of oil cooling which provides effective cooling of engine oil is established also. The lower fairing of the engine draws up air and directs to additional cooling of the engine.
Chassis and suspension
The entire Geon Stinger 250 frame is robot-welded and made of high-strength steel. Much attention is paid to this. Because there should be no cracks on the frame even in the event of an impact. After all, the frame is part of the cooling system.
Front fork Stinger inverted type - diameter 37 mm, shock absorber stroke 116 mm. The fork is quite powerful for this class of motorcycles and provides good feedback and controllability of the motorcycle in combination with effective damping of irregularities.
The design of the rear shock absorber with a built-in gas tank filled with high pressure nitrogen is adopted to reduce the oil temperature; it can provide greater restorative damping force when riding a motorcycle at high speed. The overall design is focused on comfort. The shock absorber provides a good level of comfort and significantly reduces the feeling of fatigue during long trips. Stroke of the back shock-absorber - 45 mm. Has adjustment of a spring preload.
The rear pendulum is lightweight - made of high-strength aluminum alloy using the latest technology. It also has a great effect on handling and comfort on bumps.
Brakes
Hydraulic disk brake systems. Diameter of a forward disk is 300 mm, behind 230 mm. The hoses are reinforced. Everything is strict and functional.
Paint and varnish coating and body kit.
To avoid discoloration due to sun exposure, the parts are painted using a special advanced technology. The paint specially developed for this model is much more steady against influence of aggressive factors, and is sprayed by works in the tight environment.
Installation of a plastic body kit is made on technology without use of screw connections that provides the best integrity and density. Mounting gaps of decorative parts are less than 0.5 mm. A prerequisite for this result, which is even rare in the automotive industry, is that the amount of deformation of the frame after welding is almost zero, again due to the latest technology.
Wheels and tires
Springless masses Geon Stinger 250 are significantly reduced due to the hollow disks of aluminum alloy, which improves the acceleration characteristics at the start and has a positive effect on the controllability and the passage of irregularities.
Both front and rear tires - radial with top compound - with good traction and anti-deformation characteristics. Wide tires are an important attribute of a good street. At the rear is a fairly wide for this class 150ka with a profile of 55. On the asphalt hook will be enough.
Ergonomics and comfort
The position of the driver on the Geon Stinger while riding a motorcycle makes long trips more comfortable thanks to the classic landing with a straight back and relaxed arms. In case of unevenness of position allows to transfer weight quickly (to rise) on legs, thanks to a classical arrangement of footboards of the driver.
When actively maneuvering, the Geon Stinger provides plenty of room to move thanks to the large seat - both in length and width.
The soft seat sponge is made on special foaming technology - provides higher comfort and is most harmoniously combined with the form of a tank for the maximum convenience of landing of the driver. And also much longer retains its properties of absorption of vibrations or shocks. The whole design concept focuses on driver comfort.
The steering wheel is installed through the vibration absorbing inner cores, which significantly reduce the transmission of vibration to the driver's hands when driving a motorcycle. Rubber footrests with an air core are similarly used to block the transmission of vibration to the feet.
Stinger 250 mirrors provide very good visibility and are easily adjustable and securely fixed thanks to special convenient swivel hinges.
Intelligent digital instrument panel. The digital LED display is clear and easy to read, it displays all the necessary information. Easy and intuitive to read at a glance. The panel is dustproof and waterproof.
The anti-theft lock with the integrated design opens and closes a cover of a gas tank and a cover of the anti-theft lock, and also controls the main lock, the seat lock and the ignition switch that is very convenient for use.
Geon Stinger 250 has excellent maneuverability, which allows you to quickly and easily overcome city congestion, etc. The light weight of 144 kg makes it easy to handle. That's what motorcycle you can really get high from control!
Other buns
Headlight Geon Stinger 250 is fully LED, like all lighting. Diode lighting reduces the load on the battery and provides high efficiency lighting in the dark. The headlight has a much higher lighting efficiency compared to traditional lamps and increases its advantage after prolonged use, as it serves and maintains high efficiency much longer. A gel battery is installed as standard.
The volume of the Geon Stinger fuel tank is 13 liters. Fully automated robotic welding in combination with low-spray fusion welding technology, which not only eliminates welding deformation, but also makes the inside clean, without slag. The fuel tank is made of two-layer galvanized sheet to prevent corrosion. Remember that this solution can be a lifesaver for the fuel system and for the engine in long-term operation.
Chain slider - wear-resistant and durable, well prevents possible noise from the chain.
Built-in internal mudguards and chain cover are installed for better protection of the driver and motorcycle from dirt.
The muffler is made of stainless steel. Effectively complements the picture of engine performance. The heat from the muffler is reliably isolated by the thermal screen which will definitely protect you and your passenger from unnecessary heat.
The maximum speed of Geon Stinger 250 is about 145 km / h, which means the approximate cruising speed on the highway about 120 km / h with a speed of about 8000 rpm,
In addition to the engine, the main feature of this model is - the overall level of performance, which I want to call nothing but high-performance! If you are given this blindfolded motorcycle then you are 100% confusing it with someone with a gorgeous Japanese four.
