If you’re serious about wrenching your Harley, you’ll always be looking for that special part that makes all the difference. Introducing the legendary Mag Wheel.
When in the 60s car drag racing started to move from being a pastime of a few aficionados to serious motor sport, equipment got ever more important. Among other things lightweight and truly round wheels capable of taking hard loads got popular. And there it was, the magical wheel, the dragster front wheel, cast from magnesium alloy. It was called mag wheel. Not long, and the first chopper jocks tried to bolt these wheels to their rides. A favorite ever since: the 12 spoke variety.
The mag wheels of yore with their respective sizes of 15” and 18” are extremely rare by now and about as easy to find as an Ironhead Sportster that starts on the first kick. Even if one of those beauties can be unearthed, it should be clear that time has never stopped nibbling away at the metal — and the task of making them compatible with Harley brakes and axles is another story.
That’s why W&W had the Cannonball MAG-12 wheels cast using the latest technology and state-of-the-art aluminum alloys which guarantee long-term trouble-free service. The hub design was changed, too, in that it accepts special adapters which allow for the installation of common H-D drum and disc brake systems.
The Cannonball MAG-12 takes its styling cues from the originals, but is certified to take loads of 350 kg per wheel, and engineered to be compatible with a variety of Harley brake and sprocket setups. The available sizes of 16” and 19” give a wide scope of application for that next custom project.Choose from wheels with a barrel polished or MAG finish. For the latter the barrel polished wheels are finely bead-blasted to achieve a dull magnesium-like appearance.
Cannonball MAG-12 wheels for models thru 1966 require 17 mm wheel axles.
Unlike with stock type spoke wheels Cannonball MAG-12 wheels require the drum to be bolted to the hub from the front side. Special bolt-on brake drums can be ordered as accessory. If you plan to keep your stock brake drum the mounting bolt circle needs to be enlarged slightly, including counterbores at the existing central grease deflector so the bolt heads clear the deflector. Drill templates to perform this job are available separately.

MAG-12 Wheels for Drum Brake
Each wheel comes with pre-installled wheel bearings and spacer. The version for FL/FX 1967-72 also includes both bearings for the brake drum.
Drill Jig Kits for Stock Brake Drums
Unlike with stock type spoke wheels MAG-12 wheels require the drum to be bolted to the hub from the front side. The existing grease deflector, however, demands the bolt circle to be enlarged slightly so the bolt heads clear the deflector. This task can be performed precisely and easily with this template in any workshop equipped with a drill press.
