Therefore, considering the long-term, it is recommended to replace all three simultaneously for a longer lifespan.\u003cbr\u003e\nThis is the rear sprocket (wheel side).\u003cbr\u003e\nTo enable fine-tuned settings, we support tuners with a wide range of tooth counts and reasonable pricing.\u003cbr\u003e\nMade from highly durable chromoly high-tensile steel.\u003cbr\u003e\nSprockets are consumables.\u003cbr\u003e\nAs a general guideline for normal driving, inspect the sprocket every approximately 1000 km (regular lubrication significantly improves the lifespan of sprockets and chains).\u003cbr\u003e\nRear Sprocket Teeth ÷ Front Sprocket Teeth = Reduction Ratio. A higher value indicates an acceleration-focused type, while a lower value indicates a top speed-focused type.\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 notice.
