AS3 Performance Factory Series rear sprockets are a game - changer. They blend the toughness of steel with the lightness of aluminium, delivering an extremely durable rear sprocket. The outer ring, made from hardened steel with a nickel coating, lasts up to 3 times longer than an aluminium sprocket. The inner ring, crafted from aircraft - grade 7075 - T6 aluminium, is up to 50% lighter than a standard steel sprocket. This sprocket has 48 teeth and fits a wide range of Kawasaki models, including 1992 - 2008 KX 125, 1987 - 2008 KX 250, and many more. Its features include a long - lasting hardened steel outer ring, a lightweight aluminium inner ring, high resistance to bending compared to aluminium sprockets (perfect for enduro), an anodised finish with AS3 Performance branding, manufacturing by a world - leading sprocket maker, testing on tough sand tracks, a 12 - month warranty from a UK company, and you'll get the exact sprocket as shown in the picture.

Using this rear sprocket is easy. Just follow your bike's normal installation process to replace the old sprocket with this AS3 Performance one. When riding, you'll notice the smooth performance and better durability right away. As for maintenance, regularly clean the sprocket to remove dirt and debris. Check for any signs of wear, especially on the teeth, every few rides. Lubricate it occasionally to keep it running smoothly. Remember, although it's very durable, avoid extreme impacts that could damage it. And if you have any issues within the 12 - month warranty period, contact the UK company for support.
