| Electrical System | 1100.0%ODI 11538360I was making a right turn in 1st gear and applying small throttle for traction but the engine cut off during the turn. This is dangerous for a motorcycle as friction and throttle is needed for a safe turn even during slow speeds. I have raised the concern to a local dealer prior to this incident. I called the local dealer and they stated that the open recall had already been completed so there is nothing else to do.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
