Chain kit standard
for Model: BMW F 900 R ABS A2 (4R90R/K83) 2023
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.
