Compatible with several small displacement models, this kit is offered for models such as RIEJU SMX 50 PRO (2008/2009) and RIEJU RR 50 (2005). Ideal for urban and city use, it will suit riders looking to replace their chain and sprocket with a "racing" oriented set. The XS-Ring seals contribute to better lubricant retention and increased sealing compared to standard seals, while the steel sprocket emphasizes durability.
Before installation, check the 13/52 ratio to adapt it to your geometry and follow the adjustment and maintenance recommendations (tension, lubrication) to maximize the lifespan of your transmission.
