Service bulletin KTB2606

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

KTM North America, Inc. has determined that a defect which relates to motor vehicle safety exists with certain model motorcycles listed above. On certain motorcycles, water could enter the throttle (e-throttle) control unit and cause it to fail. A loss of engine power increases the risk of a crash. To remedy this defect, the original e-throttle assembly on all affected motorcycles must be replaced with the new e-throttle assembly that is now available.
