The RENTHAL 520R1 13/49 chain kit is designed for motocross: a complete transmission with a refined look and components suited for off-road use. The standard quality 520 chain, in a Gold/Black mix, is paired with a 13-tooth sprocket and a 49-tooth ultra-light aluminum rear sprocket, featuring a mud-resistant profile to minimize dirt buildup during rides.
This kit is aimed at motocross riders looking for a lightweight and mud-resistant setup. The aluminum sprocket reduces the apparent weight of the drivetrain, and its mud-resistant profile helps to clear debris between the teeth. Note that the non-sealed chain requires more frequent lubrication and wear checks compared to an O-ring chain.
Common compatibility: Kawasaki KX 250 F (KX250Y) 2011–2012. Manufacturer reference: 482419.
