4 liter jug of high quality German Liqui-Moly Racing 4T Synthetic 10W-40 engine oil, 1 liter bottle of Liqui-Moly 75W90 Synthetic Racing gear oil, plus a Mahle oil filter, drain bolt crush washer, and a final drive crush washer/O-ring set. This is the synthetic engine oil with API-SL JASO MA rating (can be used in the wet clutch on K1200 series bikes) and the fully synthetic 75W90 gear oil (GL-5 rating). This is enough for 1 engine oil and 4+ final drive changes on your bike with some left over for topping up. We will include enough final drive washers, etc for 4 changes. For all K1300S/R & K1300GT bikes. Please note: Liqui-Moly has changed their packaging on their gear oil from 500ML bottle to 1000ML bottles. This kit now contains one 1000ML bottle of gear oil as shown in the inset pic, not the 500ML bottle shown in the main pic. Compare to BMW's retail price of $100 plus and save here!
