I am a very satisfied owner of a 1995Yamaha XJ 900 Diversion motorcycle.The vehicle is absolutely trouble-free but due to its age, the swingarm bearings had to be replaced.I purchased a set of Tourmax bearings.The bearings and the simmering rings supplied in the set matched perfectly which made the replacement a pleasure.Now my equipment rides like new again.I would recommend this set to anyone who has a similar fault to eliminate in their equipment.If all the parts were made with such accuracy, I could boldly become a mechanic ;)
