If you only replace one of these components, the worn parts that were not replaced will prevent the new part from performing optimally and shorten its lifespan. Therefore, replacing all three simultaneously is recommended for long-term durability.\u003cbr\u003e\n This is the rear sprocket (wheel side).\u003cbr\u003e\n We support tuners with a wide range of tooth counts and reasonable pricing to enable precise adjustments.\u003cbr\u003e\n Made from high-tensile chromoly steel, boasting high durability.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a guideline for general riding, please inspect your sprockets approximately every 1000 km (regular lubrication significantly extends the life of both sprockets and chains).\u003cbr\u003e\n Rear sprocket teeth ÷ Front sprocket teeth = Reduction ratio. A larger number indicates an acceleration-focused setup, while a smaller number indicates a top-speed-focused setup.\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 illustration purposes only, and the design and specifications of the product shown are subject to change without notice.
