The aluminum sprocket reduces unsprung weight for a more responsive rear wheel behavior, while maintaining a racing aesthetic thanks to the golden hue.
Known compatibilities: particularly suitable for YAMAHA YZ 450 F (CJ18 2014, CJ15 2013, CJ10 2009). Check the number of teeth and pitch before installation for a precise fit.
