CBR150 is a 150cc motorcycle under Honda, and "428-47T" usually refers to the specifications information related to the sprocket and chain of the motorcycle
428 "represents the model of the chain and is a commonly used chain specification for small displacement motorcycles. Among them, "4" indicates that the length of each section of the chain is 4/8 inches, which is 12.7mm; 28 "indicates that the inner width of the chain is 2.8/8 inches, approximately 8.9mm"47T" means that the sprocket has 47 teeth. Here, the sprocket generally refers to the driven sprocket (the sprocket on the rear axle), and the driving sprocket (installed on the engine output shaft) usually has fewer teeth than the driven sprocket. Different gear combinations can affect the transmission ratio of motorcycles, which in turn affects the vehicle's power output and speed performance. For example, a larger ratio of the number of teeth on the driven sprocket to the number of teeth on the driving sprocket will result in a greater torque for the motorcycle during starting and climbing, but high speeds may be subject to certain limitations; On the contrary, a smaller transmission ratio is beneficial for improving the vehicle's high speed, but the starting and climbing force may be relatively small
