Bulletins for the same vehicles and component
| KTB2106 | 2021-12-01. Service bulletin. On affected motorcycles there is a possibility that the preload force of the return spring is too low and does not meet the specified tolerance. This could result in the brake piston not being returned to its original position which in rare cases can impair the function of the front brake. To ensure the highest level of safety, performance, reliability and customer satisfaction, it is necessary to replace the front brake master cylinder piston return spring on all affected motorcycles. |
