Designed to equip 450cc machines like the KTM SX, this kit combines a 520 pitch transmission with RENTHAL R1 design suitable for muddy environments.
- Sprocket: ultra-light aluminum, mud-resistant profile to limit dirt accumulation and facilitate removal during rides.
- Chain: 520 pitch, gold/black color, standard quality (non-sealed), non-sealed links — regular maintenance and lubrication recommended.
- Ratio: 14-tooth front sprocket / 52-tooth rear sprocket (14/52), standard fit for motocross.
- Type: RENTHAL R1, designed for off-road use requiring maneuverability and mounting durability.
This kit is aimed at motocross riders looking for a lightweight and easy-to-maintain solution, especially on muddy terrain. Note: the non-sealed chain requires more attention to lubrication than sealed models.
