I have a system that uses 4 spherical bearings, 2 on each side. The specifications are 3/4" ID for your 2002~current pivot shaft. These bearings have a 1,020 load x (4) =4,080 pounds total load and a side load of 50% or 4,080 pounds & sells for $114.00 total including S&H USPO with tracking # & no signature required or insurance.
FYI the stock bearings have 314 pounds total load & 157 pounds of side load for both.
Call or write me including your exact year and model motorcycle. Allow 4~5 days for delivery anywhere in the CONUS.

Here are the specs on the Aurora bearing. They are not the complete specs as the Forum wouldn't allow more than 20 images a post. The radial static load capacity is 137 kN. Converted to pounds it is 30,798 lbs. This is a plain bearing. When they talk about the ball they are referring to the inner part. It rides on a Teflon barrier that makes it self lubricating against the outer part of the bearing. Considering that the MOCO used to use cleveblocks, this may well be a real upgrade even from ball or roller bearings. I will certainly try them this winter when I'm doing upgrades.
No, those are not the bearings.... those are similar to the factory bearing. No seal, and use what I believe is a nylon sheet as the "lubrication" point which would be too soft and deflect almost immediately causing more play than the factory setup. Note the media says it is a "plain" bearing. Not sure what that means.
The best bearing for this application is the Aurora bearing that I specified. It is durable, high precision, and has seals on it. As to fitment years, I will look that up in my parts manual later today and post back here the factory part number. If your bike uses the same part number then it will fit yours too! If not, Aurora makes a host of different sizes and I'm sure you could source the correct one.

Indeed, it is why we use Aurora bearings in our race cars. The load rating on their products is amazing (and hey being made in America instead of China is such a welcome change).
Imagine, you are going to replace the factory crappy sphericals with new ones that are rated at 30,000 lbs EACH... now remember that there are two of them in the swing arm, then you have over 60,000 lbs of bearing load capability. When we use these in race cars I can tell you, they just do not fail! I have been using Aurora now for 15+ years and I can tell you quite simply, there is no better product out there. If there was, I would be using it!

No affiliation, just a happy customer :-)
Your 2003 came factory with spherical bearings only, no Clevie blocks. Prior to 2002 the FL's & other models had Clevie blocks. I do not have time to give the part numbers of both models. The pivot shaft on 2002's & your bike is 0.75" or 3/4" and not 25mm. Am I reading your drawing wrong? Please help.
