The RENTHAL 420R1 14/50 chain kit is designed for motocross riders who want lightweight, understated, and easy-to-maintain equipment. Comprising an ultra-light aluminum sprocket with a mud-resistant profile and a gold/black 420 R1 chain, this kit offers a racing aesthetic while minimizing dirt and mud accumulation on the sprocket.
This kit will suit motocross riders looking for a simple installation and lightweight transmission. Note that the non-sealed chain requires regular maintenance (lubrication and tension checks) to ensure longevity. The ultra-light aluminum sprocket helps reduce unsprung mass, and its mud-resistant design limits dirt accumulation on the track.
