aftermarket motorcycle speedometer tachometer

Our company can provide aftermarket motorcycle speedometer tachometer 2 in 1 gauge. Please see below picture:

Speedometer and tachometer are two different things. They can only be coincidentally consistent at a certain speed, not at every speed. Moreover, at the same speed, they are not consistent at all times. For example, at the same speed, different road conditions, gears, loads, acceleration or constant speed will affect the speed and engine speed. For ordinary motorcycles, the speedometer may be "consistent" with the tachometer only when they are running at the highest gear and medium speed, but this "consistency" is not really consistent. The unit of the speedometer is km / h, and the unit of the tachometer is 1000 rpm. For example, there is only 6 for 60 km / h and 6000 rpm, but it is not "consistent".

The rotational speed and the vehicle speed are not consistent. They represent different data. Only at a certain speed can they be "consistent". Because of the vehicle speed, gear, load, different driving stages and other reasons, the speed of 50 km / h does not necessarily correspond to the speed of 5000 rpm. After instrument replacement, due to different instrument settings, there may be deviation from the original comparison. This is normal, indicating that the replaced instrument is not exactly the same as the original instrument.

The first gear of the motorcycle climbs 10-20 yards. 20-30 yards in the second gear. Third gear 30-50 yards. Fourth gear 50-60 yards. The fifth gear is over 60-100 yards. Take the ordinary 125 motorcycle as an example, the average speed of 50-60 yards per hour is the most fuel-efficient. Don't let the engine work at low speed and high speed. You can't shift to third gear until the second gear is 40. This will increase the speed a bit. This will increase fuel consumption for a long time.

If the several lines mentioned refer to the lines of the gear display switch, there should be 6 lines in the car with the 5th gear, because there is also a neutral line that needs wiring. Five forward gears plus one neutral line is 6 lines. The first gear is the starting gear, and generally the second gear is the starting gear. After the first gear is started, the second gear will be changed to the third gear immediately. Therefore, the second to third gears are equal to the climbing gear, and the torque is large. The third to fourth gears are used when people slowly queue up.
