Continental Tire the Americas, LLC (âCTAâ) has determined that certain TKC 80 tires fail to conform to Federal Motor Vehicle Safety Standard No. 119, "New pneumatic tires - other than passenger cars." CTA has initiated a tire safety recall to remove these tires from service. The KTM models listed above were originally equipped with TKC 80 brand tires. CTA has determined that groove cracks in the tread rubber developed during internal testing. Groove cracking may appear during the tire service life and can lead to tread separation, increasing the risk of a crash. On the specified 690, 890, 1090 and 1290 Models listed above only the originally equipped TKC 80 front tire is affected and needs replaced. On the specified 250, 350, 450 and 500 EXC-F Models listed above both the originally equipped TKC 80 front and rear tires are affected and need replaced. Customers that still have originally equipped TKC 80 tires mounted on their motorcycle are eligible to have the recall tire replacement performed by an authorized KTM dealer.

On affected motorcycles there is a possibility that the bellow style gasket can be damaged caused by deviations during assembly. Damage to the bellow gasket may affect the function of the clutch slave cylinder. This could result in the rider noticing a change in shifting behavior and the clutch becoming inoperable to the point where the clutch will not disengage when the clutch lever is pulled in. To ensure the highest level of safety, performance, reliability and customer satisfaction, it is necessary to replace the clutch slave cylinder on all affected motorcycles that have a bellow style gasket clutch slave cylinder mounted (Fig. 1).
