I was going to order an oil filter wrench (76mm with 12 flutes) for the R18 today when I realized it uses the same oil filter wrench as I already use on my K1600 Grand America. Yowza - saved me a whopping $12 that can now be used for many other farkles and accessories for my R18 and other bikes. Not sure where to start but I'm sure those savings will go far! Life is good...
