AS3 Performance Factory Series rear sprockets are a game - changer. They cleverly blend the strength of steel with the lightness of aluminium, giving you 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 fits various 2021 - 2023 Fantic models like XX 125, XE 125, XX 250, XXF 250, XEF 250, XXF 450, and XEF 450 (except XEF 250 Trail). Key features include a long - lasting hardened steel outer ring, a super - light aluminium inner ring, resistance to bending and damage compared to aluminium sprockets (perfect for enduro), an anodised finish with AS3 Performance branding, manufacture by a world - leading sprocket maker, testing on tough sand tracks, a 12 - month warranty from a UK company, and the sprocket you'll receive exactly matches the picture.
Using this rear sprocket is straightforward. Just install it on your compatible Fantic bike according to the standard installation procedure for sprockets. When using it, avoid extreme impacts as much as possible, even though it's more resistant to damage than aluminium sprockets. For maintenance, regularly clean the sprocket to remove dirt and debris. You can use a mild detergent and a soft brush. After cleaning, dry it thoroughly. Check the tightness of the sprocket regularly to make sure it's securely attached. If you notice any signs of excessive wear or damage, contact the UK company for assistance under the 12 - month warranty.
