Pit Bike Chain - 420 Gauge
Most CRF50 style bikes run a 51 or 102 link chain depending on how you count a link.
Most CRF70 style bikes run a 52 or 104 link chain depending on how you count a link.
The pitch is 420 which fits 6mm wide sprockets.
These chains are liable to stretching and if funds allow we recommend the heavy duty chain as a replacement.
