My Kawasaki 250 Ninja calls for lubricating the swing arm bushings and the Uni-Trak bushings every 6000 miles, and the folks on the Ninja forum strongly suggest doing so. They say Kawasaki is none too generous with the grease on initial assembly, and when I did mine I found that was the case. It might be placebo effect, but mine seemed more compliant after I lubed it. It is a real nuisance, because everything has to come off including the swing arm. God forbid they should put Zerks on it.
My Yamaha 250 Star called for lubing the swing arm bushings at 4000 miles. Once again, the swing arm has to be removed. It definitely needed grease. See above comment about Zerks.
I tried to remove the swing arm on my S40, but didn't have enough muscle to loosen the through bolt. So I settled for moving the swing arm through its (limited) travel, feeling for play and roughness. Based on my other two bikes, I strongly suggest removing the swing arm and greasing the bearings. They probably need it.
Good words from Char, as usual.....
It's been my personal experience (with my old motocross bike) that, after you get in there and do the swingarm/linkage lube job right, using a robust, high quality grease, you may never need to do that job again. I suggest using a high quality, water
proof aluminum-complex grease. Lithium-complex greases are typically just water
resistant and will emulsify in the presence of water.....not a good thing.
For applications not calling for a moly content, I like this stuff:
If the application DOES call for moly grease, I like this:
