Cannonball Parts - New Horizons for Big Flatties, Knuckles and Pans

Cannonball Parts - New Horizons for Big Flatties, Knuckles and Pans

If you’re one of them lucky fellers to own and ride a big Flathead, Knuckle or Panhead you probably know that fear of being on your own if something goes wrong inside your half-century old mill. Where do you get essential parts without breaking the bank? Do an online search and wait till three in the morning to be outbid by some avid collector? Good luck with that. Try the swapmeet? If you got all the time in the world, why not? Use NOS from a reliable source? Not bad, IF the NOS part that made it unused across half a century onto your bench is still servicable.

Here’s the good news: To make the good old Big Twins purr again, parts and components by Cannonball are now available for Flatheads, Knuckleheads and Panheads.

IN ERWIN’S TRACKS.

The Cannonball brand is a homage to record setting Erwin George ’Cannonball’ Baker, who in 1914 crossed the continental USA from coast to coast in then unheard of eleven days on his motorcycle. He would surely agree, that words alone get you nowhere.

That’s why we take all our parts, test them, install them, optimize them, put them in a chassis and let them take all the punishment we can find on thousands of road miles. Hundreds of hours and many meltdowns later, when everything is flying like a cannonball, they’re ready for all those Flatheads, Knuckles and Panhead Big Twins out there.

Sidevalve engines determined the factory’s model policy for many decades and it wasn’t before 1973 that the last Servi-car with Flathead powerplant rolled off the production line. To make sure that these legends will continue to eat miles, miles and more miles, Cannonball crankcases and cylinders provide that any tired sidevalve Big Twin can be put back into service.

Knucklehead Parts
Knucklehead Parts
A true legend and without a doubt one of the milestones in the history of Harley-Davidson. Introduced in the year 1936 the ohv-engined models proved to be a huge success for the Motor Company, because customers quickly realized the outstanding qualities of this design. Consequently the Knucklehead became the prototype of the distinctive Milwaukee Big Twins, that influenced all successive models to the present day.

Panhead Parts
Panhead Parts
When the Motor Company introduced its latest ohv Big Twin engine in 1948, almost immediately nicknamed Panhead for obvious reason, it was accepted enthusiastically by all H-D aficionados until its production end in 1965. However, it started a second and probably more important career in 1969 when it starred in the cult movie Easy Rider as the powerplant of Dennis Hopper’s and Peter Fonda’s choppers. The rest is history.
