The official notice
Defect
On certain motorcycles, when upshifting between first and second gear, if the rider fails to engage second gear, a neutral condition will exist and continued opening of the throttle will cause very high engine RPM. If the rider then shifts into second gear without disengaging the clutch under the very high engine RPM condition, an excessive load can be applied to the powertrain, which can cause the drive chain to stretch and potentially come off or break resulting in a loss of motive power, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealer will replace the Engine Control Module (ECM) with a reprogrammed unit and perform drive chain inspection. Based on the results of the drive chain inspection, replace the drive chain and sprocket, if necessary.
