Normal Tooth Warranty
This extended warranty applies only to the normal wear that will occur to the tooth profile geometry on the rear belt sprocket. Normal wear is considered wear that occurs when the protective hard coating has worn away exposing the underlying aluminum, changing the profile of the sprocket tooth significantly. Warranty is for five years from date of purchase with unlimited mileage. Warranty claims will require a dated receipt showing proof of purchase from an authorized Harley-Davidson Dealer. Warranty only applies to original purchaser of the sprocket. Original owners name must appear on the receipt.
All applications of the sprocket require installation of upper and lower original equipment belt guard or Harley-Davidson accessory belt guards where applicable. Warranty is voided if these items are not installed.
Excessive chips found in the tooth profile due to abnormal riding conditions will void warranty. Occasional chips in the tooth are to be considered normal and should not be considered a warranty issue.
Decorative external chrome carries the standard parts and accessories 90 day warranty. Staking the flange on the backside of the sprocket will pierce through the chrome, this is to be considered a normal process and should not be considered an issue.
All warranty claims must be pursued through your authorized Harley-Davidson Dealer.
