SFR O-Ring chains achieve permanent lubrication sealing
between pin and bush, which ensures longer lifetime and
minimum maintenance. With solid bushing, high quality of pin
material and 4-side riveting, SFR offers both standard and
reinforced O-Ring chains; but we recommend reinforced
O-Ring chains, since they have even better performance
covering almost all the ranges of motorcycles.

performance High 1.5-2 SFR X-Ring chains are specially designed for use on
Running Distance high powered as well as touring bikes.
Low
Squashed With a special 4-lips seal ring, lubrication is safely
Squashed sealed inside the chain during its lifetime.
With low frictional resistance, SFR X-Ring chains
operate much softer and cooler, and engage
better than traditional O-ring chain.
At the same time, X-ring considerably increases the
lifetime of the chain as well.
