Scottoiler are great. I wouldn’t have a chain driven bike without one. Not sure what the current range is like as my newest one is 15 years old and going strong, but the double sided nozzle is worth considering. My TDM had a Scotty from new and had first chain and sprockets changed at 28k miles, second at 48k miles and still ongoing. One thing I did notice both times was that it was the front sprocket that had worn. Rear and chain still looked relatively unworn by comparison. I use X Ring chains without issues.
