Therefore, considering the long term, replacing all three parts simultaneously is recommended as it will last longer.\u003cbr\u003e\n This is the rear (wheel side) sprocket.\u003cbr\u003e\n To enable fine-tuned settings, we support tuners with a wide range of tooth counts and reasonable pricing.\u003cbr\u003e\n Made from highly durable chrome molybdenum high-tensile steel.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a general guideline for normal driving, please inspect your sprocket every 1000km (daily oiling significantly extends the life of sprockets and chains).\u003cbr\u003e\n Rear sprocket tooth count ÷ Front sprocket tooth count = Reduction ratio. A higher value indicates a focus on acceleration, while a lower value indicates a focus on top speed.\u003cbr\u003e\n Compatible models: Monkey\/Baja, Gorilla (Z50J-1300017-\/AB27-1000001-1899999), Monkey FI (AB27-1900001-)\u003cbr\u003e\n *The image is for illustration purposes only, and the design and specifications of the products shown may change without prior notice.
