1, the car engine work environment is poor, according to the terrain, obstacles and make the different and sometimes the engine will almost destroyed, the operation of the engine's demand is simple, strong,
Therefore, although the car is based on 80,125,250 emissions mostly two-stroke, but without exception, pre-mixed lubrication methods are used, this advantage is not concerned about whether the work of the oil pump failure.
High-speed car work started in 5000 to switch over the output power, in order to reduce the reciprocating piston and ring resistance CR125 after 85 years at the factory is only one piston ring
The manufacturer of the piston and piston rings ensure that only the working life of 40 hours, more than 40 hours while on the power output curve is not guaranteed;
2 car designed to take into account the removal of the parts often need replacement, 87 years after the car engine in the right crankcase cover with special clutch assembly from the rapid removal
Co-device side cover, when you need to replace the clutch plates or assembly without having to remove the entire right side cover, simply unscrew the clutch side cover on the clutch can be easily demolished, and 87 years ago the car does not have this device;
3, the driving method, there is no gates car keys first, and only emergency turn off a switch, and no throttle adjustment screw, so when you launch the car, if the throttle back
In the end it will turn off the car, the drivers will change according to engine speed in time for an oil, so the car's ignition system is always maintained at the minimum speed on without flame, which is often used to open
Friends of the two vehicles the biggest problem: As long as the two cars hanging in the neutral gear, hands do not touch the car does not turn off, can throttle back the car as long as the death of more than 2-3 seconds to fire, and made a rush,
Arena did not touch the car novice or long time players often this phenomenon: accelerated known everything about genome turn straight, the joint brake, back block, throttle back, dead of fire, and then start the player when the front has not
See trace, the solution is often the vehicle training, understanding the performance of the car after all right;
4, the car's rear sprocket installed on the side of the wheel is a two-bearing design, installation disc tray is a single bearing design on one side, there are three within the rear hub bearings, and the two vehicles is also
Different places; 8, professional car very strict requirements for fuel, according to the actual situation at home and 97 is generally used in petrol and fully synthetic oil, a proportion of ready-made jar, the best
If not, must be very precise configuration of mixed oil, so as not to cause inaccurate because the ratio piston, cylinder damage, recommend the use of syringe cylinder and configured according to the ratio of 40-50:1.
5, racing for the race, asked the body weight, engine horsepower torque output of large, good shock absorption properties, so different from the ordinary civilian vehicles, in appearance canceled
Race has nothing to do with the signal system and lighting system, leaving only the ignition system and engine rotor be as small as possible, to reduce the magnetic motor inertia is beneficial to the engine output horsepower,
Enhanced throttle response agility. In addition, because the car's ground clearance Large, shock stroke length, so the car's seat height of 91 cm or more generally, the new car seat in about 1 m high, which is not very high for tall drivers is a problem;
6, the car's frame divided into the main frame and sub-frame of two parts, removable to facilitate replacement shock assembly. The main frame for different car manufacturers and different materials,
97 years from the beginning as Honda, CR series of 125 (98 onwards) and 250CC's car main frame using high strength aluminum alloy material, and 80CC of the frame on with the Yamaha YZ series
Suzuki's RM series, as Kawasaki's KX series of high strength steel to manufacture other brands such as Europe, KTM, Hu swa that are all used to manufacture high-strength steel tube frame car,
No matter what material, which process only one purpose - ensuring the strength of the case body weight reduction;
7, car shock absorber with nitrogen gas, hydraulic, and spring means three in one, according to driver's weight, track topography, obstacles to the difficulty of different stretch of the spring, nitrogen pressure,
Hydraulic adjust, good shock absorption response commensurate with the drivers on the agility, flexibility or so before the shock can be felt slightly different;
