Sirris makes the following LIMITED WARRANTY with respect to its suspension products:
LIMITED TWO (2) YEAR WARRANTY ON SUSPENSION PRODUCTS
Subject to the limitations, terms and conditions hereof, Sirris warrants, to the original retail owner (consumer) of each new Sirris suspension product, that the Sirris suspension product, when new, is free from defects in materials and workmanship. This limited warranty expires two (2) years from the date of the original Sirris suspension product retail purchase from an authorized Sirris dealer or from a Sirris authorized Original Equipment Manufacturer where Sirris suspension is included as original equipment on a purchased vehicle.

This limited warranty is only applicable to Sirris suspension purchased new from an authorized Sirris source and is made only to the original retail owner (consumer) of the new Sirris suspension product and is not transferable to subsequent owners.
Should it be determined, by Sirris in its sole and final discretion, that a Sirris suspension product is covered by this limited warranty, it will be repaired or replaced, by a comparable model, at Sirris’s sole option, which will be conclusive and binding. THIS IS THE EXCLUSIVE REMEDY UNDER THIS LIMITED WARRANTY. ANY AND ALL OTHER REMEDIES AND DAMAGES THAT MAY OTHERWISE BE APPLICABLE UNDER THIS LIMITED WARRANTY ARE EXCLUDED, INCLUDING, BUT NOT LIMITED TO, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR PUNITIVE DAMAGES.

BREAK-IN PERIOD NOTE: The Sirris F43 fork is a symmetrical closed cartridge design with two independent sealed dampers. It will break-in over the first 5 hours of use with significant improvements in friction. We recommend that you don’t make significant changes to clicker positions or valving until after the 5 hour break-in period. To best maintain the performance and durability of your product under normal use, Sirris recommends that you have regular fork and shock maintenance performed according to the service intervals listed below.
It is important to remember that service intervals can vary depending on climate, trail conditions and riding frequency. Servicing your suspension requires special knowledge and tools. If you are unsure about working on your own suspension, contact your authorized Sirris Dealer for more information on general suspension maintenance.
Failure to follow these recommendations could affect your warranty.
Long term non-use: If the motorcycle has been sitting unused for more than one year, complete inspection is necessary and maintenance is recommended.
WARNING: Modification, improper service, or use of aftermarket replacement parts with Sirris forks and shocks may cause the product to malfunction, resulting in SERIOUS INJURY OR DEATH. DO NOT modify any part of a fork or shock, including the fork clamps, steerer, upper and lower leg tubes, or internal parts, except as instructed herein. Any unauthorized modification may void the warranty, and may cause failure or the fork or shock, resulting in SERIOUS INJURY OR DEATH.
WARNING: Sirris products should be serviced by a qualified service technician, in accordance with Sirris specifications. If you have any doubt whether or not you can properly service your Sirris product, then DO NOT attempt it. Improperly serviced products can fail, causing the rider to lose control resulting in SERIOUS INJURY OR DEATH.
