Greasing the axles & wheel bearings

Greasing the axle is simple. Spray the axle with cleaner, wipe clean, and then apply a layer of fresh grease. Any standard grease is fine. Bel Ray waterproof grease works for a lot of MC needs (and trailer, and car, and bicycle). If there's too much, it'll get scraped off. For streetbikes that live indoors this shouldn't be a major concern.

As for the wheel bearings, you just pry off the dust cover and then force as much clean grease into the bearings as possible. Some people like to clean them first (flush with parts cleaner) but just having grease in there is FAR more important than having clean grease (so long as the dust covers stay intact). Anyway, you force the grease in with your fingers. It's messy (wear nitrile gloves) but simple.

Another thing that needs greasing are the spacers for the rear wheel. We have seen several which have visible wear, even though they are not supposed be a load-bearing item.

Also, pull the sprocket carrier and fill/pack the bearing with grease every time the wheel is off. This is a semi-open bearing.

Grease suggestion: Look for a waterproof grease in a lithium soap with molybdenum disulfide, preferably with the words "needle bearings" and "extreme pressure" on the package.
