If you only replace one of them, the worn parts that weren't replaced will prevent the new part from performing at its original capacity and durability, leading to premature replacement. Considering the long term, replacing all three simultaneously is recommended as it ultimately extends their lifespan.\u003cbr\u003e\n Front (engine side) sprocket.\u003cbr\u003e\n Made from S45C (high carbon steel), which boasts light weight and high durability.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a guideline for general riding, inspect the sprocket approximately every 1000 km.\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 setup; the smaller the ratio, the more top-speed-oriented the setup.\u003cbr\u003e\n When using for TDR50\/80, please purchase the genuine circlip (99009-18400).\u003cbr\u003e\n Compatible models: TZR50, TZ50, TZR50R, TDR50\/80, RZ50, etc.\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
