RIEJU MR 300 2021 AS3 PERFORMANCE FACTORY REAR SPROCKET 51T RED

AS3 Performance Factory Series rear sprockets are a game - changer. They cleverly blend the strength of steel with the lightness of aluminium, offering you an incredibly durable rear sprocket. The outer ring, made from hardened steel with a nickel coating, can last up to 3 times longer than an aluminium sprocket. Meanwhile, the inner ring crafted from aircraft - grade 7075 - T6 aluminium is up to 50% lighter than a standard steel sprocket. This sprocket fits 2021 Rieju MR 300 Racing, Pro, and Ranger models. Key features include: a hardened steel outer ring that outlasts aluminium sprockets, an ultra - light aircraft - grade aluminium inner ring, better resistance to bending and damage compared to aluminium sprockets (perfect for enduro), an anodised finish with AS3 Performance branding, production by a world - leading sprocket manufacturer, testing on the world's toughest sand tracks, a 12 - month warranty from a UK company, and you'll receive the exact sprocket style as shown in the picture.

Using this sprocket is straightforward. Just replace your old rear sprocket with this one following the standard procedures for your 2021 Rieju MR 300 model. When it comes to installation, make sure to double - check that all the bolts are tightened properly to avoid any issues during use. As for maintenance, it's a good idea to clean the sprocket regularly, especially after riding on dirty or sandy tracks. You can use a mild cleaner and a soft brush to get rid of dirt and debris. Also, keep an eye on the wear and tear of the teeth. If you notice any signs of excessive wear, like teeth that are getting too thin or damaged, it might be time to replace the sprocket. And don't forget, this sprocket comes with a 12 - month warranty, so if you have any problems within that time, just reach out to the UK company.
