Dazzling headlight design
The newly-designed LED headlights have higher brightness and longer life. The sharp-shaped LED position lights, turn signals, and daytime running lights are not only energy-saving, but also durable, and give a strong visual impact. Wonderful combination of the headlight and decorative light are very attractive to passersby's eyes, when it runs, it will became the focus on the road.
Large-capacity fuel tank design
Large-capacity fuel tank design, full shape and strong endurance; the overall design, workmanship, and quality of the whole motorcycle show your tasty , galvanized inner tank to prevent oil filter cotton from being blocked due to rust and fuel tank leakage.
Electronic instrument
In addition to the functions of the original ordinary electronic instruments, EFI electronic instruments also add the following functions: 1. Add an EFI fault indicator,tell us whether the EFI system is normal follow its instructions.
New upgrade configuration
The newly upgraded black shrink tube with a short handle, a matte black direction pressure block, and the front disc brake cup main pump is made of aluminum alloy. It is independently developed and has a novel and fashionable shape.
CBS Disc brake
When the rear brake is individually controlled, the CBS system can redistribute the rider's wishes reasonably to the front and rear wheels, allowing the motorcycle to slow down and stop in the shortest distance; the delay valve added to the system upgrade can better make both wheels can get proper and effective braking force.
Front shock absorption
The newly upgraded 32mm-diameter upright sleeve front shock absorption can deal with sudden bumpy roads during driving. The stability and strength of the whole vehicle will be improved to ensure driving safety.
Non-slip tire
Famous brand Cheng Shin Tire, let you calmly cope with complicated road conditions
New chain box
Fashionable new chain box, the triangle plate with full of energy.
Muffler
Double exhaust muffler port makes exhaust smoother, its speed faster, and the sound thicker and more powerful and without noisy. Newly designed one-piece anti-scalding board, which not only improves the insulation effect but also looks more beautiful.
Square tube rear fork
Equipped with 4 bearings and 4 oil seals to solve the problem of shaft wear, improve service life and vehicle comfort.
Air filters
The newly design enlarges the air filter, the capacity reaches 4.0L, and the air inlet is located under the seat cushion to solve the problem that the dust is easy to enter from the side of the air filter.The air filter element separates the air filter into two internal cavities to filter the air more fully.
Guard bar
Advanced shape, beautiful and practical of the guard bar make you safer while driving.
EFI system
The EFI system uses the latest generation of EFI systems for motorcycles developed by Continental Germany. It uses the latest control strategy of Continental and adopts an integrated design. It has the advantages of high cost performance, high control accuracy, and strong system stability. It can pass the national emission regulations, adapt to the harsh environment requirements such as high cold, high heat, and plateau, and has outstanding performance in terms of power, fuel consumption and driving feel./div>
Sprocket seat
The internal structure with Newly designed, tightly matched with cushioning rubber, reducing the movement problem of aluminum wheel and sprocket seat, to increase product life.
Simple and generous rack
The simple and generous racks take place of old cage steel tube design. The toughness of the racks has significantly strengthened the carrying capacity and fully meet daily needs.
Taillight
The simple rear taillights, the shape and the vehicle style fit together, LED is more eye-catching.
TBF250 Engine
Integrated cooling cylinder cover
The avant-garde integrated cylinder head cover, the rocker arm and the rocker shaft are directly mounted on the cylinder head cover, the rocker arm seat is saved, and the mechanism is simplified.At the same time, an improved thimble pin-type start-up decompression device is used, which is easy to be assembled, has good reliability and low maintenance cost.
Multi-channel cooling cylinder head
The unique multi-channel cylinder head increases the heat dissipation efficiency, which fully improves the heat dissipation characteristics of the engine, so that improve the working performance of the it.
Large heat sink cylinder block
The large-blade cylinder block enlarges the blades on the basis of the ordinary cylinder block to take away the heat, fully improves the heat dissipation characteristics of the engine, and thereby improves the engine performance. The new design enlarges the structure of the blade cylinder, and the appearance is more beautiful.
Enhanced crankshaft
The crankshaft is optimized and adjusted again. The optimized crankshaft has lighter weight and better balance effect.
Lightweight piston
The piston assembly adopts a lightweight design, which not only improves the reliability of the engine, but also reduces the reciprocating force of the engine for a better comfort experience. At the same time, a number of advanced technologies such as three PVD piston rings are used to greatly improve the reliability and air tightness of the piston, making it more wear-resistant and more durable.
Optimum Design of Oil and Gas Separation Maze
Aiming at the problem that the large displacement engine is used for a situation of high temperature and high speed at a long time, the oil in the box is ejected from the exhaust hole of the box due to the sharp increase in the air pressure in the box. The novel structure of the oil and gas separation labyrinth inside the box is specially designed to ensure the long-term safe use of large displacement engines.
Geared oil pump drive
The original NT-type chain-driven oil pump structure has the problem that the chain is easy to stretch and fall off, which causes the oil pump to be unable to pump oil. The gear oil pump with optimized double-chamber structure is now used to greatly improve the oil durability of the oil pump.
