Therefore, in the long run, it is recommended to replace all three parts simultaneously for better longevity.\u003cbr\u003e\nThis is the rear sprocket (wheel side).\u003cbr\u003e\nTo allow for fine-tuning, it supports tuners with a wide range of teeth and reasonable pricing.\u003cbr\u003e\nMade of highly durable chromoly high-tensile steel.\u003cbr\u003e\nSprockets are consumables.\u003cbr\u003e\nAs a general guideline, inspect the sprocket approximately every 1000km of normal riding (the lifespan of the sprocket and chain can be significantly extended by daily lubrication).\u003cbr\u003e\nThe larger the reduction ratio (rear sprocket tooth count ÷ front sprocket tooth count), the more emphasis is placed on acceleration; the smaller the value, the more emphasis is placed on top speed.\u003cbr\u003e\nCompatible models: RZ50 5R6\/1HK\u003cbr\u003e\nRX50 (cast wheels) all models\u003cbr\u003e\nTZM50R all models\u003cbr\u003e\nYB-1 58E all models\u003cbr\u003e\nYB-1 (FOUR) 5JE all models\u003cbr\u003e\nYB50 58E\u003cbr\u003e\nTT-R50E all models\u003cbr\u003e\n*The image is for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
