If you only replace one part, the worn unreplaced parts will prevent the new part from performing optimally and shorten its lifespan, ultimately leading to earlier replacement. Therefore, from a long-term perspective, it is recommended to replace all three parts simultaneously as they will last longer.\u003cbr\u003e\n Front (engine side) sprocket.\u003cbr\u003e\n Made from S45C (high carbon steel), known for its light weight and high durability.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a general guideline, inspect your sprocket every 1000km of normal driving.\u003cbr\u003e\n (Regular lubrication significantly extends the lifespan of sprockets and chains.)\u003cbr\u003e\n The larger the reduction ratio (rear sprocket teeth ÷ front sprocket teeth), the more acceleration-oriented the vehicle; the smaller the ratio, the more top-speed-oriented it is.\u003cbr\u003e\n Compatible models: CBR250R (MC41)\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
