En 125 motorcycle, what is the tire pressure before and after?

The front wheel is generally 170- 180 kPa, and the rear wheel is 200-220 kPa.

General motorcycle repair shop electric pump will be fixed at about 3 kg air pressure. When the sound of air flow disappears, it means that the air pressure of the tire is the same as that of the pump (the air will not flow). Motorcycle tires are heavily loaded on the rear wheels. You feel them swell. Press hard, just a little.

Air pressure is the key to tires. Too high or too low will shorten the service life of tires. If the air pressure is too low, the deformation of the carcass will increase, cracks will easily appear on the sidewall, and buckling and deflection will occur at the same time, which will lead to excessive heating and promote rubber aging.

Extended data

Harm of long-term high tire pressure;

If the tire pressure is too high, the damping stroke of the tire itself will be shortened, thus reducing the comfort when driving. In short, if the tire pressure is high, the car will become very bumpy when driving, reducing comfort and easily inducing safety hazards.

On the other hand, the tire pressure is too high, the contact area with the ground is reduced, and the proper grip of the tire itself is reduced. Riding in rainy or bad weather is easy to cause sideslip or even rollover. Therefore, before driving, you must test whether the tire pressure is enough by hand, or you can pat it gently with a wooden stick according to the elasticity of the tire. The most accurate method is to measure with a pressure gauge.
