RENTHAL 520R3 reinforced chain kit 13/50 — a set designed for motocross where the demands on the transmission are at their highest. This kit includes a reinforced 520 R3 chain in gold/black, mounted with a 13 tooth sprocket and a 50 tooth crown made of ultra-light aluminum with a mud-resistant profile to limit dirt buildup between the teeth.
The combination of a reinforced chain + O-Ring seals helps retain lubricant in the links and limits the penetration of dust and mud, useful on special stages and trails. The aluminum crown reduces unsprung weight while facilitating the removal of debris thanks to its mud-resistant profile.
Category: Motocross. Examples of compatibility: HUSQVARNA WR 125 (2001, 2008, 2013). Before installation, check the pitch (520) and the spacing of your model to confirm compatibility.
