Therefore, considering the long term, replacing all three simultaneously is recommended for better longevity.\u003cbr\u003e\nThis is the rear sprocket (wheel side).\u003cbr\u003e\nTo allow for precise settings, it supports tuners with a wide range of teeth 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 approximately every 1000km (regular lubrication significantly improves the lifespan of sprockets and chains).\u003cbr\u003e\nThe 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\nCompatible models: NSR50\/80 All models\u003cbr\u003e\nNS-1 All models\u003cbr\u003e\nNS50F All models\u003cbr\u003e\nNSR MINI\u003cbr\u003e\nNSR50R\u003cbr\u003e\nXR50 Motard AD14 All models\u003cbr\u003e\nXR100 Motard HD13 All models\u003cbr\u003e\nAPE50-D (FI model) AC18 All models\u003cbr\u003e\nAPE100-D HC13 All models\u003cbr\u003e\nNSF100\u003cbr\u003e\n*The image is for illustration purposes only.
