Hi quality STEEL (not plastic like some similarly priced wrenches out there) oil filter wrench for all K1200S/R/R-Sport and K1200GT (GT models from 2005 and later only), R1200RT/ST/R/ST/GS/GSADV (non liquid cooled bikes only), F800/650 (twins), K1600GT/GTL bikes. Will fit our Mann, Mahle oil filters and our Beemerboneyard brand filters as well as the OEM BMW filter # 11427673541. PLEASE READ: BMW HAS CHANGED THE FILTERS THEY SPEC FOR K1200S/R/GT (FROM 2005), F800/650 TWINS & S1000RR BIKES. IF THE FILTERS YOU ARE USING LOOK LIKE THE INSET PIC TO THE LEFT (12 GROOVES) THIS IS THE CORRECT WRENCH. Why pay $75 for the BMW wrench or over $35 for a fancy aluminum wrench?
