4 liter jug of high quality German Liqui-Moly Street 4T Synth 15W-50 engine oil, 1.25 liters of Liqui-Moly 75W90 Synthetic gear oil, plus a Mahle oil filter, drain bolt crush washer, and transmission/final drive crush washer set. This is the fully synthetic engine oil with API-SN+ JASO MA2 rating and the fully synthetic 75W90 gear oil (GL-5 rating). This is enough for 1 engine oil change on your bike with about a little left over for topping up and 1 trans and final drive oil change. For all R18 models. At times we may be out of stock on the Mahle OC306 oil filters. In those instances we will substitute a Mann MW75 oil filter which is identical. 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.
