Therefore, for long-term economy, it's recommended to replace all three at once, as they will last longer.\u003cbr\u003e\n This is a front (engine side) sprocket.\u003cbr\u003e\n Made from S45C (high carbon steel) for lightness and high durability.\u003cbr\u003e\n Sprockets are consumables.\u003cbr\u003e\n As a general guideline for normal driving, inspect the sprocket approximately every 1000 km.\u003cbr\u003e\n (Regular lubrication significantly extends the life of both the sprocket and chain.)\u003cbr\u003e\n Rear sprocket tooth count ÷ Front sprocket tooth count = reduction ratio. A higher number indicates a focus on acceleration, while a lower number indicates a focus on top speed.\u003cbr\u003e\n Compatible models: RZ50 5R6\/1HK\u003cbr\u003e\n DT50 3LM all models\u003cbr\u003e\n TZM50R all models\u003cbr\u003e\n Mate 50 3AC1-9\/4AT1-9\u003cbr\u003e\n Mate 80 4AW1-4\u003cbr\u003e\n YB-1 (Four) 5JE all models\u003cbr\u003e\n TT-R50E all models\u003cbr\u003e\n TT-R90 5HN1-4\u003cbr\u003e\n *Images are for illustration purposes only, and the design and specifications of the actual product may change without notice.
