We Can Now offer a final Drive Rebuilding Service for AirHead R Series , R1100 & R1150 Paralever , K100’s & K1100’s , also the later type R1200 /K1300 Final Drives
For Thread Repairs (Timesert ) not inferior Helicoils
We Only use Genuine BMW Bearings and seals they are different to even aftermarket FAG & INA Bearings its to do with tolerances and seals are directional.
R1200 & 1250 Liquid cooled Final drives currently only have Genuine seals available no Bearings, only aftermarket ones which we find are not good enough quality for us to use and guarantee our work. So currently the only option is a Genuine new unit at an eye watering £1500 Inc vat (02/2022) .
If your bike is under 5 years old with a full service history, you maybe able to persuade BMW into a good will gesture.
This is the proper tool
