Reports submitted to NHTSA, shown in the owner's own words
WHEN DOWNSHIFTING FROM 3RD GEAR, THE TRANSMISSION FREQUENTLY BYPASSES 2ND GEAR AND GOES INTO NEUTRAL. THIS IS TRUE NEUTRAL, NOT A FALSE NEUTRAL, AS THE NEUTRAL LIGHT COMES ON IN THE INSTRUMENT PANEL. THIS SITUATION IS VERY DANGEROUS AND COULD LEAD TO LOSS OF CONTROL OF THE MOTORCYCLE. WHEN DOWNSHIFTING FROM 3RD GEAR, THE EXPECTATION IS THE MOTORCYCLE WILL BE IN 2ND GEAR WHEN THE CLUTCH IS RELEASED. WHEN THIS PROBLEM OCCURS, A LOSS OF CONTROL CAN OCCUR WHEN THE MOTORCYCLE DOES NOT SLOW AS EXPECTED, POTENTIALLY LEADING A RIDER TO OVERSHOOT A CORNER, INTERSECTION, ETC. THIS PROBLEM CAN OCCUR WHENEVER THE MOTORCYCLE IS IN MOTION AND ATTEMPTING TO DOWNSHIFT FROM 3RD GEAR TO 2ND GEAR. THIS HAS HAPPENED NUMEROUS TIMES SINCE I BOUGHT THE BIKE IN 2019. WHEN I BROUGHT THE BIKE IN FOR THIS CONCERN, TWO DIFFERENT TIMES, THE DEALER COULDN'T FIND ANYTHING WRONG.
