SPROCKET ALU MSE BMW 41T BLK

The 7075 T651 aluminum we use for these sprockets receives an extra tempering which reduces distortion and provides optimal thickness vs. typically thinner 7075 T6 sprockets

100% machined, no stamping or grinding

Optimal tooth thickness results in maximum tooth and chain contact

Fits BMW ’08-’12 F650, ’08-’18 F800 GS models w/ 10.5 mm bolts.
