Continental today announced a voluntary tyre exchange program covering approximately 170,000 Continental 120/70 ZR 17 and 120/70 R 17 motorcycle tyres. Market feedback indicates that a very small number of these tyres have exhibited a condition in the tread and/or belt which may lead to separation and possible air loss. Continental has not received any reports of accidents or injuries in connection with this condition. The exchange program is being initiated to avoid any potential risk to road-users. The affected tyres were sold to original equipment and replacement customers worldwide between 2007 and 2014.
