Chain kit standard
for Model: BMW F 850 GS ABS (4G85/K81) 2019
Here you get the chain set in the standard version, i.e. sprocket, chain wheel and chain in the ratio as it was originally delivered.
In our configurator you can select the sprocket and the chain wheel if you wish, the chain length is calculated on the basis of the selected sprocket or chain wheel.
Conversion Chainset Configurator
Here you can get a Conversion Chainset with the original gear ratio.
In our configurator you can select the sprocket and the sprocket wheel, if desired. The chain length is calculated on the basis of the selected sprocket and the sprocket wheel.
It is possible that an exact match of the selected gear ratio with the chain is not possible and the chain may have to be shortened, but you will never get a chain that is too short.
The conversion kit deviates from the original chain kit pitch, which is very popular, for example, for race track use.
A chain with a higher tensile load is always used as the standard chain in the conversion kit, as a (smaller) chain is usually used here.

D.I.D X-ring chain 525VX3/122 with rivet lock
- The X-ring DID drive chain differs from the DID chain with O-ring by improved sealing of the chain link plates by means of an inserted X-shaped sealing ring.
- An "X" is formed in the cross-section. This ring seals at 4 contact points and thus achieves even better protection against contamination and leakage of the grease filling from the inside of the chain.
- This results in an even longer service life of the chain and thus of the complete motorbike chain kit. With proper care and average use, the chain kit usually lasts around 25,000 KM or more
Technical data:
525 pitch / 122 links / running index 4000
Tensile strength 4524kg / with rivet lock
Advantages:
- improved sealing
- very high running performance
- up to 50% less friction compared to an O-ring seal
- Perfectly equipped, you are well equipped against dirt and water
Scope of delivery
1 x D.I.D. X-ring chain
