As mentioned in previous posts, I didn't have the time in our production schedule to make another run on more "trailer" balls and didn't know when I would. As an alternative, I flipped the project off to the lead-machinist that would actually be building the balls. I provided the material/machines/drawings and he provided the time and expertise. Therefore, I am kind of out of the loop on the trailer balls. If others can get the motorcycle specific balls, I'm happy. If the fellow building them can make a little for his time, hopefully, he will be happy, as well.
The pic below is a comparison to the Rivco anodized aluminum ball (left), a ball from a production run I had made some time back (center) and the newest generation ball (right). The new ball is slightly taller with an even smaller "shank" or "neck" (0.750" OD) than the previous generation to allow even more swiveling clearances. The balls are constructed from 17-4PH material (171ksi...twice as strong as commercial heat-treat 4140 steel) and will never rust, peel, flake or the like. You could pick up your motorcycle with this ball and shake it hard without a ball issue.
The limited clearance for the Rivco ball is what got me started building balls in the first place. Rivco makes a top-notch hitch, IMO, but their balls didn't work out so well for me. This was after a flying trip across the Cherola Skyway...ball/coupler would run out of clearance in hard cornering and thereby, I was torquing the trailer's suspension to get the bike over far enough to make the high-paced corners. Not for the faint of heart.
The fellow building these balls does not tow a motorcycle trailer. He bounced the idea of building these balls off some of his friends and word got out. He has already sold several to some local GoldWing riders. This is the balls I will be pulling all my trailers with as of next week.
I am not participating in the finances, order-taking, shipping, etc. for this project as I don't want to mix business with my hobby, however, I will assure you and guarantee that if you order the ball, you will get the ball. They have set up a PayPal account (trailerballs @ yahoo.com) which is, also, their email address. A young lady named Jennifer (who is, also, an employee here) will be the one processing the orders. From past experience, I can say with confidence that she gets stuff done promptly and efficiently.
The price for the trailer balls is $50 flat-rate shipped anywhere in the United States. A good price considering the raw 2" material is over $24 per unit. I'm sure they would be more than glad to ship outside of the US with an adjustment in shipping cost. Shop now while quantities last.
If I can answer any technical questions on the balls, I will gladly do so. If you have any questions about purchasing, shipping, etc., please direct them to Jennifer at the above email address.
