This is the regular mineral based engine oil with API-SG/SJ/SL rating and the fully synthetic 75W90 gear oil (GL-5 rating). This is enough for 1 engine oil change on you K-bike with a little left over for topping up and 1 trans and final drive oil change. For all K75/100/1100 bikes and also K1200RS, K1200LT and K1200GT bikes (GT through 2005 only). Please note: Liqui-Moly has changed their packaging on their gear oil from 500ML bottle to 1000ML bottles. This kit now contains 1.25 liters of gear oil as shown in the inset pic, not the 3 500ML bottles shown in the main pic.
