Therefore, considering the long term, it is recommended to replace all three simultaneously for better longevity.\u003cbr\u003e\n This is the rear sprocket (wheel side).\u003cbr\u003e\n To enable fine-tuning, it supports tuners with a wide range of teeth counts and reasonable prices.\u003cbr\u003e\n Made from highly durable chromoly high-tensile steel.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a general guideline for normal driving, inspect the sprocket every 1000km (regular lubrication significantly extends the lifespan of sprockets and chains).\u003cbr\u003e\n The larger the reduction ratio (rear sprocket teeth count ÷ front sprocket teeth count), the more acceleration-oriented it is; the smaller the ratio, the more top speed-oriented it is.\u003cbr\u003e\n Compatible models: RZ50 5R6\/1HK\u003cbr\u003e\n RX50 (cast wheels) all models\u003cbr\u003e\n TZM50R all models\u003cbr\u003e\n YB-1 58E all models\u003cbr\u003e\n YB-1 (FOUR) 5JE all models\u003cbr\u003e\n YB50 58E\u003cbr\u003e\n TT-R50E all models\u003cbr\u003e\n *The image is for illustrative purposes only, and the design and specifications of the product shown may change without prior notice.
