The valves of the front and rear wheels of motorcycles are different.

Yes, the front and rear wheels of motorcycles have different valves. Generally speaking, the valve of the front wheel is shorter and the valve of the rear wheel is longer. This is because the rear wheels of large-row motorcycles bear more load during driving and need more air to cool the tires and brake system. The valve of the front wheel is relatively short, in order to reduce air resistance and improve driving stability and handling performance.
