BROS160 48T-16T "represents the sprocket combination suitable for BROS160 motorcycles. The following is a specific explanation:
BROS160： It should refer to a motorcycle model with a displacement of 160cc. However, currently common 160cc motorcycles include the New World Honda Fossa 160, the Grand Theft Auto DR160, etc. There is no model directly named "BROS160", which may be a relatively niche or specific manufacturer produced model. Generally, motorcycles with a displacement of 160cc are at a moderate level in terms of power and performance, suitable for urban commuting and some short distance outdoor rides, and can meet the basic needs of daily cycling
48T - 16T： Representing the combination of teeth on the sprocket, 48T is the number of teeth on the rear sprocket, and 16T is the number of teeth on the front sprocket. The transmission ratio formed by this tooth number combination is 48 ÷ 16=3. A larger transmission ratio means that the vehicle has relatively stronger starting and climbing power when the engine output power is the same. For example, when starting at a traffic light on a city road, one can accelerate to a suitable speed relative to the speed; When encountering slopes with relatively small gradients, it is also relatively easy to climb up. However, a larger transmission ratio can also result in relatively high engine speeds during high-speed driving, which may increase fuel consumption and limit the vehicle's high speed
