If you only replace one of these, the worn parts that were not replaced will prevent the new part from performing as intended and achieving its full durability, leading to an earlier replacement. Therefore, considering the long term, it is recommended to replace all three parts simultaneously as it will last longer.\u003cbr\u003e\n Front (engine side) sprocket.\u003cbr\u003e\n Made from S45C (high carbon steel), which boasts lightweight and high durability.\u003cbr\u003e\n Sprockets are consumable parts.\u003cbr\u003e\n As a general guideline, inspect your sprocket approximately every 1000 km of normal driving.\u003cbr\u003e\n (Regular lubrication significantly extends the life of sprockets and chains.)\u003cbr\u003e\n The larger the reduction ratio (rear sprocket teeth ÷ front sprocket teeth), the more acceleration-focused it is; the smaller the ratio, the more top speed-focused it is.\u003cbr\u003e\n Compatible models: YSR50, RD50, MR50, YB50, GT50, OR50, GAG Pocket\/Vogel (all models)\u003cbr\u003e\n YB-1 58E (all models)\u003cbr\u003e\n YB50 58E\u003cbr\u003e\n Birdy 50 FNO.BA41A-100001~, etc.\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the products shown are subject to change without prior notice.
