100 ML bottle of genuine Magura "Blood" red hydraulic mineral oil. This is the fluid Magura recommends for use in their hydraulic clutch systems found on all 2005 & later K1200/1300S, R, S, & GT bikes and also the new K1600 bikes. Not for use on the R1200 Hex/Camhead or water-cooled bikes. Also not for use on older bikes which have their reservoir caps marked "DOT4 Fluid". One bottle is enough for one clutch bleed with some left over.
