THIS VEHICLE HAD A FAILED STATOR WHICH CAUSED THE VEHICLE TO SHUTDOWN COMPLETELY ON THE HIGHWAY. THE VEHICLE WOULD NOT RESTART. THE STATOR IS THE CHARGING SYSTEM. THIS IS A KNOWN DEFECT AS APRILIA HAS ISSUED AN UPDATED PART #. JUST ONE DEALER IN THE US HAS SOLD 185 OF THE REPLACEMENT NEW PART # STATORS. THIS EFFECTS ALL 2011-2015 TUONO V4 IN THE US WHICH THERE IS APPROX. 1000 UNITS IN THE FIELD.

THIS COMPLAINT CONCERNS THE STATOR (CHARGING) ASSEMBLY FOR THE APRILIA TUONO V4. IN MY EXPERIENCE, I HAVE HAD TO REPLACE MY CHARGING SYSTEM, AT MY COST, BECAUSE THE STATOR BURNED ITSELF UP, PREVENTING THE CHARGING OF THE BATTERY. IN READING A FORUM FOR THIS BIKE, IT IS A WIDESPREAD ISSUE AND HAS CAUSED MANY TO BE STRANDED. MY STATOR BURNED ITSELF UP WITH MY ODOMETER SHOWING 8,113 MILES. APRILIA HAS PRODUCED A NEW, UPDATED STATOR AND ROTOR ASSEMBLY, BUT REFUSES TO RECALL THE MOTORCYCLE TO CHANGE THIS $350 ASSEMBLY. THE VEHICLE WAS STATIONARY WHEN I ATTEMPTED TO START MY MOTORCYCLE AND THE VOLTAGE WAS LESS THAN REQUIRED FROM THE BATTERY. MANY OWNERS BELIEVE THE BATTERY IS THE INITIAL CULPRIT AND REPLACE IT ERRANTLY.
No injuries · No fire · No crash
THE STATOR QUITE CHARGING AND VOLTAGE DROPPED TO BELOW 10.2V ON 6/28/2015 11,236 MILES STALLED ON HIGHWAY. DEALER REPLACED UNDER WARRANTY BUT ON 5/24/2016 @15,500 MILES STATOR HAS FAILED AGAIN.
