RIGHTS RESERVED: Zipper’s Cycle, Inc., hereinafter referred to as Zipper’s, reserves the right to make changes in design, materials and specifications on products, engines and kits without incurring liability or obligation with respect to similar products previously manufactured or sold. Our R&D program never stops; improvements may be made at any time.


Zipper’s has always been a leader in the manufacture and sale of the highest quality performance parts for Harley-Davidson based motorcycles. We continually strive to provide products and services in support of racing and high performance, which reflect our reputation and ongoing efforts at improving the sport of motorcycling.

Zipper’s warrants all parts and accessories produced for and by Zipper’s to be free from defects in design and workmanship. Should the parts be found to be, or become, defective during any stated warranty period, Zipper’s will, at its option, repair or replace any, or all, defective parts. Zipper’s will maintain no obligation under the terms of this warranty in the event the parts become defective as a result of improper assembly, installation, break-in, maintenance or use, or any other misuse or mistreatment of the parts including, without limitation, operation of the parts with fuels, oils or lubricants not conforming to specifications published by Zipper’s or continued operation of the parts after a defect or malfunction occurs, is identified or suspected.

Zipper’s will have no obligation under this warranty for parts defective due to alteration including, but not limited to, chroming, polishing, powder coating, painting, removing and modifying components, shot peening, bead blasting, modification, repair or unauthorized service, even when such services or modifications may be performed by Zipper’s at the request of the end user.

All items not manufactured by Zipper’s are warranted to be free from defects under the terms outlined by the specific manufacturer. Any parts determined to be defective will be repaired or replaced, at the option of the manufacturer, in a prompt and just manner.

Determination of obligation under the terms of this warranty will only be made once the components or assemblies have been received and inspected by Zipper’s or the third party component manufacturer.

Parts identified or intended as racing components, or identified with the word “Magnum”, carry no warranty, regardless of installation.

There is absolutely no warranty on the following:

  • Any parts used in a racing application
  • Any part that has been physically altered, improperly installed or maintained
  • Any product used in improper applications, abused or not used in conjunction with the proper parts
  • Any product that has been placed into, or continued in operation, without proper setup, to include but not limited to carburetor jetting, ignition timing or lubrication
  • Any product that has been damaged by ingestion or introduction of foreign matter or objects through the intake, oiling system or other source

All items sold, for installation by the end user, are considered by law to be customer assembled items and carry no liability to the distributor or maker.

This warranty does not cover any consequential, incidental, or special damages arising out of the use of, or inability to use the parts, components or vehicle to which the parts or components are installed. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion may not apply to you.
